Use these selected concepts to connect Ontario dentists’ professional obligations with practical decisions. Start with the regulatory and ethical foundations, then apply them to consent, patient relationships, reporting, records and business arrangements. Each concept includes a resolved example and a specific error to avoid.
Regulation and professional foundations
1. Statutes and College by-laws have different functions
In Ontario, the Dentistry Act, 1991 and the Regulated Health Professions Act, 1991 govern how dentistry is regulated, while RCDSO by-laws govern how the College operates. The Dentistry Act establishes the scope of practice and controlled or authorized acts for dentists.
Worked example: An exam question asks which instrument establishes the scope of dental practice in Ontario. The correct answer is the Dentistry Act, 1991, not an administrative RCDSO by-law dealing with College operations.
Mistake to avoid: Treating every College document, including administrative by-laws, as if it were provincial legislation.

2. A registration certificate can restrict practice
A valid certificate of registration is required to perform procedures authorized to dentists. An academic certificate permits practice only in a dental faculty or school, or a formally associated hospital or facility; private practice and personally charging dental service fees are prohibited.
Worked example: An academic registrant proposes seeing patients in a private office on weekends and billing them personally. The academic certificate does not permit that practice, although the associated faculty or facility may charge for services.
Mistake to avoid: Assuming a dental qualification alone permits practice in every setting, including private offices.
Supporting reference: [18]
3. Registrar investigations do not require a formal complaint
Separate from the complaints process, the Registrar may appoint an investigator when there are reasonable and probable grounds to believe a dentist committed professional misconduct or is incompetent. Information from insurers, other professionals, public health units or other sources can prompt consideration of an investigation.
Worked example: An insurer sends the College documented concerns about a dentist without any patient complaint. The Registrar can assess whether reasonable and probable grounds exist to appoint an investigator; the informant may not learn the outcome.
Mistake to avoid: Assuming the absence of a signed patient complaint prevents any regulatory investigation of a dentist.
Supporting reference: [25]
4. Investigation outcomes include remediation and referral
After a Registrar investigation, the ICRC may take no further action or, to improve practice, conduct or competence and protect the public, give advice, order remediation or education, issue a formal caution, arrange an undertaking, refer concerns to Discipline, or refer for incapacity proceedings.
Worked example: The ICRC reviews a concern and orders the dentist to complete specific education. This response is remediation aimed at improving practice, not an automatic referral of the matter to the Discipline Committee.
Mistake to avoid: Treating every Registrar investigation as an automatic disciplinary proceeding with a guaranteed outcome.
Supporting reference: [25]
5. Fiduciary duties put patient interests first
Fiduciary law obliges dentists to act with integrity, loyalty and utmost good faith in patients' best interests, avoid conflicts of interest, protect confidentiality and provide record access; business interests must never displace these duties.
Worked example: A dentist drafts an office policy discouraging record transfers because copies reduce recurring revenue; the dentist rejects the policy, recognizing that record access is a fiduciary duty owed to patients.
Mistake to avoid: Deferring a patient's records request for weeks because releasing files might reduce the practice's recurring revenue.
Supporting reference: [8]
6. Patient autonomy requires understandable collaboration
Respecting autonomy means giving clear, accurate information the patient understands and encouraging shared decision-making with the patient, or with a substitute decision-maker, family member or caregiver only when that person's involvement is authorized.
Worked example: A capable adult attends with a talkative relative who answers every question; the dentist addresses the patient directly and asks what authority, if any, the relative holds before proceeding.
Mistake to avoid: Treating a confident accompanying relative's answers as the patient's treatment decisions without checking any authorization.
Supporting reference: [8]
7. Recognizing competence limits supports referral
Nonmaleficence requires maintaining competence, recognizing limitations and referring when necessary. Prescribing is limited to dentistry's scope for patients of record, requires a logical connection to a current clinical indication, and self-prescribing is prohibited.
Worked example: A patient of record asks for a prescription for an unrelated skin rash; the dentist declines, explaining prescribing covers only oral-facial conditions, and directs the patient to a physician.
Mistake to avoid: Prescribing for a stranger's non-dental complaint, or writing a self-prescription, outside the dental scope.
8. Justice requires attention to bias and access
Justice requires services and administrative decisions free from discrimination on protected grounds under the Ontario Human Rights Code, recognizing one's own bias and preventing it from influencing care, and addressing each patient's unique barriers to access.
Worked example: Staff assume a patient with a disability cannot participate in treatment decisions; the dentist corrects this, adapting communication to the individual's actual needs rather than relying on the group assumption.
Mistake to avoid: Concluding an individual patient cannot consent because of a stereotype about the patient's disability group.
Supporting reference: [8]
9. Assigning tasks does not remove dentist accountability
Dentists remain responsible for meeting their legal, professional, and ethical obligations whether they assign tasks to staff or other health care professionals, or work with an organization or other party while practising. Delegation cannot transfer that accountability away.
Worked example: A dentist hires a marketing contractor who publishes misleading claims about the practice's services. Because the dentist remains accountable for obligations arising in the course of practising, she must correct the misleading information and address compliance herself rather than relying on the contractor's involvement.
Mistake to avoid: Assuming an employment or service contract eliminates professional responsibility.
Supporting reference: [8]
Consent and treatment decisions
10. Consent must fit the proposed treatment
Consent must be obtained from the capable patient or, if the patient lacks capacity, from the patient's SDM. It must relate to the specific treatment proposed, be informed, given voluntarily without duress or coercion, and not obtained through misrepresentation or fraud. Consent is a process beginning before treatment and renewed throughout its course.
Worked example: During a filling appointment, a dentist finds decay extending near the pulp and proposes root canal treatment instead. Because the substantially different treatment was not what the patient originally agreed to, the dentist revisits the decision and obtains consent specific to the changed proposal before proceeding.
Mistake to avoid: Treating initial agreement as unlimited permission for later care.
Supporting reference: [6]
11. Informed disclosure includes alternatives and no treatment
For consent to be informed, the dentist must ensure the patient or SDM receives the treatment's nature, its expected benefits, its material risks and material side effects, information about alternative courses of action, and the likely consequences of not receiving the treatment.
Worked example: After explaining a proposed crown's nature, benefits, material risks and side effects, a dentist asks for consent. The patient says they assumed a crown was their only choice and asks about declining it, so the dentist describes alternative courses of action and the likely consequences of not receiving the crown before seeking a decision.
Mistake to avoid: Treating disclosure about the recommended option alone as sufficient.
Supporting reference: [6]
12. Material risk depends on seriousness and likelihood
Dentists must use judgment about what a reasonable person in the patient's circumstances would require to decide about treatment. Disclosure includes risks and side effects that are common even when not grave, and those that are rare but particularly significant. Low probability alone does not make a serious consequence immaterial.
Worked example: In a hypothetical case, a proposed treatment has one established common, less serious side effect and one established rare, particularly significant risk. The dentist discusses both, since neither rarity nor lesser severity alone justifies omission.
Mistake to avoid: Applying a universal probability cutoff for disclosure.
Supporting reference: [6]
13. Understanding requires more than delivering information
Dentists must be satisfied the patient or SDM actually understood the information, take reasonable steps to facilitate comprehension, remain available to answer questions, and allow adequate time to reach a decision.
Worked example: After a rushed explanation of a root canal, the dentist asks the patient to describe the procedure back; her confused answer prompts a slower re-explanation with a translator before consent is sought.
Mistake to avoid: Treating a patient's nod or silence as proof that the explanation was genuinely understood.
Supporting reference: [6]
14. Treatment cost disclosure is a College requirement
Before initiating treatment, dentists must disclose expected fees, anticipated additional costs that may arise, and relevant insurance information. The RCDSO standard imposes this duty; it is not a requirement under the HCCA, 1996.
Worked example: Before starting a crown, the dentist quotes its fee, warns that a needed build-up would cost extra, and checks the patient's annual coverage limit.
Mistake to avoid: Assuming every disclosure duty, including fees, comes from the HCCA rather than the College standard.
Supporting reference: [6]
15. Express consent is advised for higher-risk treatment
Consent may be express or implied, but express consent is advised when treatment is more than mildly painful, carries appreciable risk, impairs a bodily function, is surgical or invasive-investigative, or significantly changes consciousness. Express consent may be oral or written.
Worked example: For a planned surgical extraction with appreciable risk, the dentist asks for a direct, explicit oral agreement after the discussion instead of inferring consent from the patient sitting in the chair.
Mistake to avoid: Believing express consent is valid only when the patient signs a written form.
Supporting reference: [6]
16. Capacity is treatment-specific and can change
Capacity means understanding relevant information and appreciating the reasonably foreseeable consequences of a decision or lack of decision. Dentists may presume capacity absent reasonable grounds to doubt it, but must reassess it for each treatment and over time.
Worked example: A patient consented clearly last month but today seems muddled; the dentist reassesses her understanding and appreciation of this specific proposed treatment before proceeding.
Mistake to avoid: Relying on a capacity assessment made months earlier without reconsidering the current treatment decision.
Supporting reference: [6]
17. A capable minor gives treatment consent directly
Ontario sets no fixed age for treatment capacity. A minor assessed as capable using the same understanding-and-appreciation criteria applied to adults must give consent directly, even when a parent or guardian is present in the operatory.
Worked example: A capable 16-year-old patient declines the recommended molar extraction while her accompanying mother approves it. The dentist records the minor's own refusal and does not proceed on the mother's agreement alone.
Mistake to avoid: Using parental agreement as a substitute for a capable minor's consent.
Supporting reference: [6]
18. A disputed incapacity finding requires review safeguards
When a patient disputes a dentist's incapacity finding, the dentist must advise them of the right to apply to the Consent and Capacity Board for review and must not provide the disputed treatment until the matter is resolved or the CCB decides.
Worked example: Before planned implant surgery, a patient insists she can consent despite the dentist's incapacity finding. The dentist explains her CCB review right and postpones the disputed surgery until the disagreement is resolved.
Mistake to avoid: Proceeding solely because a relative accepts the dentist's assessment.
Supporting reference: [6]
19. An SDM must satisfy both rank and eligibility
For an incapable patient, consent must come from the highest-ranking statutory SDM who also meets every eligibility requirement: capability regarding the treatment, minimum age of 16 unless a parent, no prohibiting court order or separation agreement, availability, and willingness.
Worked example: An incapable adult's authorized attorney for personal care cannot be reached. The dentist moves down the statutory hierarchy to the next eligible person, an adult daughter who is available and willing to decide.
Mistake to avoid: Choosing whichever relative reaches the office first.
Supporting reference: [6]
20. Emergency consent exceptions require all stated conditions
Treatment without prior consent is permitted only when communication needed to give or withhold consent is impossible despite reasonable practical efforts, delay would prolong severe suffering or risk serious bodily harm, and there is no reason to believe the patient refuses treatment.
Worked example: An unconscious patient cannot communicate, no practical means of enabling communication is found despite reasonable efforts, delay risks serious bodily harm, and nothing suggests he would refuse. Only then may treatment proceed without consent.
Mistake to avoid: Treating every urgent appointment as authority to bypass consent.
Supporting reference: [6]
21. Consent forms support a documented discussion
A signed form records a discussion but is not consent itself. Dentists must still meet all substantive consent requirements, retain signed forms in the record, and use professional judgment on documentation detail, advised to be more detailed for complex, risky, or strictly cosmetic care.
Worked example: A patient signs a form for implant surgery after a brief conversation covering only cost. Before proceeding, the dentist discusses risks, benefits, and alternatives, including no treatment, and documents that discussion.
Mistake to avoid: Treating a patient's signature as proof of consent when the required discussion never adequately occurred.
Supporting reference: [6]
Professional boundaries
22. Professional boundaries continue outside the clinic
Boundaries apply at all times, including non-clinical contexts, because the power imbalance inherent in the dentist-patient relationship persists. Violations can be unintentional and occur when a dentist's personal interests are placed ahead of the patient's best interests.
Worked example: At a community fundraiser, a dentist asks a current patient to invest in a personal business venture, placing the dentist's interests ahead of the patient's.
Mistake to avoid: Assuming that meeting a patient socially ends the professional boundary obligations of the treating relationship.
Supporting reference: [9]
23. Dual relationships need active safeguards
A secondary personal or professional relationship with a patient can complicate care and increase boundary-violation risk. Dentists must preserve informed consent, confidentiality, and conflict management, and must end the treating relationship, following discontinuation requirements, if care is undermined or a conflict cannot be resolved.
Worked example: A dentist's business partnership with a patient collapses into litigation, making objective treatment planning impossible despite attempted resolution; the dentist ends the treating relationship in accordance with the Managing Conflicts standard and discontinuation requirements.
Mistake to avoid: Believing a patient's signed agreement to a dual relationship removes the need for ongoing safeguards.
Supporting reference: [9]
24. Trauma-informed touch protects patient control
Care should assume a patient may have experienced trauma or violence. Avoid unnecessary touch, obtain explicit or implied consent outside emergencies, seek consent before comforting touch, communicate throughout care, and never rest instruments on the patient's body, even over a bib.
Worked example: Before a routine examination, a dentist explains each step, asks permission before adjusting the bib, keeps instruments off the patient's chest, and pauses when the patient tenses, seeking consent before any comforting touch.
Mistake to avoid: Resting instruments on a draped patient's chest because the bib seems to make it acceptable.
Supporting reference: [9]
25. Patient agreement does not defend sexual abuse
Patient consent or initiation is never a defence for sexual abuse; clinically appropriate touching, behaviour or remarks are excluded. A spouse means someone married to the dentist or cohabiting in a common-law relationship outside marriage continuously for at least three years, and the exemption applies only when the dentist is not providing dental care at the time. For a non-spousal sexual partner, care must be emergency or minor in nature, meaning short-term, episodic care without significant intervention for a relatively less serious condition, and the dentist must have taken reasonable transfer steps or have no reasonable opportunity to transfer care.
Worked example: A patient on the schedule invites her dentist for dinner and suggests intimacy afterward; he declines, because her agreement or initiative never excuses sexual conduct with a current patient.
Mistake to avoid: Treating a patient's mutual agreement or initiation as a regulatory defence to sexual abuse.
Supporting reference: [9]
26. Ending treatment does not immediately permit a sexual relationship
Dentists must not become involved in a sexual relationship with a former patient for at least one year after the dentist-patient relationship terminates, a date that should be documented. Separately, they must never communicate or behave with a patient for the purpose of eventually pursuing a sexual relationship. The one-year rule is a minimum, not a guarantee that later conduct is appropriate.
Worked example: Four months after documenting a patient's termination date, a dentist considers beginning a sexual relationship with her; the minimum one-year prohibited period has not elapsed, so he must not proceed.
Mistake to avoid: Using termination of treatment as an immediate workaround to begin dating a former patient.
Supporting reference: [9]
27. Sexual-history questions require clinical relevance
Dentists must not ask about or comment on a patient's sexual history, behaviour, or performance unless the information is relevant to providing dental care; when a relevant question is necessary, they must explain the clinical reason for asking and record it.
Worked example: Before asking about a patient's intimate history, the dentist cannot identify any relevance to the current dental assessment, so she omits the question entirely rather than satisfying curiosity.
Mistake to avoid: Asking sexual-history questions to build informal rapport without any clinical indication or documented reason.
Supporting reference: [9]
Managing conflicts and ending care
28. Conflict differs from an irreparable breakdown
A conflict negatively affects trust or respect and may compromise safe, effective care, while a breakdown means essential trust or respect is lost and cannot be regained. Reasonable resolution efforts are required in the patient's best interests, except where prior reasonable efforts failed, abuse or harassment occurred, or the patient or a closely associated person poses a risk of harm to the dentist, other patients or practice staff.
Worked example: A patient angrily disputes the office's cancellation policy but makes no threats; no prior resolution effort has failed. The dentist discusses his concerns and possible next steps instead of declaring an irreparable breakdown and dismissing him.
Mistake to avoid: Treating every disagreement or policy dispute as automatic grounds for ending the dentist-patient relationship.
Supporting reference: [14]
29. Conflict discussions must preserve confidentiality
When conflict resolution involves someone other than the patient, such as a relative or staff member, the dentist may disclose personal health information only with the patient's consent or where the law permits; the dispute itself grants no access.
Worked example: An adult patient's sibling, upset about a billing dispute, phones demanding implant details. The dentist explains that without the patient's consent or a legal basis, no health information can be shared.
Mistake to avoid: Treating a relative's involvement in the dispute as automatic authorization to disclose treatment details.
Supporting reference: [14]
30. Termination requires a defensible, lawful rationale
A dentist-initiated ending, before the natural or expected completion of care, needs a clear, defensible rationale that considers the patient's best interests, and it must never contravene legislation, including discrimination on protected grounds under the Ontario Human Rights Code.
Worked example: Before dismissing a patient, a dentist reviews the proposed rationale and realizes it rests solely on the patient's sexual orientation, a protected ground, so the decision is reassessed and abandoned.
Mistake to avoid: Assuming professional judgment about ending care overrides Ontario Human Rights Code obligations.
Supporting reference: [14]
31. Written termination notice supports continuity
Make reasonable efforts to notify the patient in writing, physically or electronically, with limited exceptions, covering the end date, other practitioners at the practice, a brief rationale, record access and transfer instructions, time-sensitive needs, and emergency-care advice.
Worked example: A retiring dentist whose associate will assume care sends written notice explaining the transition, who takes over treatment, who holds the records, and how patients can contact the practice with questions.
Mistake to avoid: Sending a letter stating only the dismissal date without record-access instructions or emergency-care advice.
Supporting reference: [14]
32. Dismissed patients need an emergency-care route
For dismissed patients losing access to care at the practice, offer at least one emergency-care route: contact details for an appropriate local service, referral to another dentist, or direct emergency care. Direct care is one option, not universally required, and any time limit on it requires judgment about the patient's needs and available alternatives. Document the advice and termination details.
Worked example: Unable to provide direct emergency care, the dentist gives the dismissed patient the phone number of a local hospital dental department and explains how to use it, then records that communication in the chart.
Mistake to avoid: Recording an emergency phone number in the chart without communicating the route to the patient.
Supporting reference: [14]
Infection prevention responsibilities
33. IPAC oversight rests with principal dentists
Every oral health care worker shares IPAC responsibilities, but implementation and oversight rest with the principal dentist(s). Dentists must ensure staff receive adequate training and that necessary supplies and equipment are available, fully operational, up to date and routinely monitored for efficacy.
Worked example: A practice installs new reprocessing equipment. The principal dentist arranges equipment-specific staff training and establishes routine efficacy monitoring, rather than assuming the assistant's prior experience with older units covers the new machine.
Mistake to avoid: Treating IPAC as exclusively the dental assistant's responsibility instead of a shared duty under the dentist's oversight.
Supporting reference: [13]
34. Written IPAC policies need review and audit
An IPAC program should include specific written policies in the Office Manual, education, and ongoing review and evaluation. Dentists are strongly encouraged to audit all core IPAC components, including instrument reprocessing. External IPAC-certified reviewers are preferred; at least annual internal audits may be reasonable only when the internal reviewer has sufficient knowledge to identify and remediate deficiencies.
Worked example: A dentist's audit reviews instrument reprocessing but skips environmental cleaning and staff education. She expands the audit to cover all core IPAC components, ideally engaging an externally certified IPAC reviewer.
Mistake to avoid: Assuming that simply possessing an Office Manual proves the IPAC program is effectively implemented and evaluated.
Supporting reference: [13]
35. Ill-patient screening must account for urgency
Patients who appear ill should be rescheduled if at all possible. When their dental condition is urgent, every effort must be made to separate them from other patients by seating them promptly in a secluded operatory, minimizing contact and droplet transmission.
Worked example: A coughing patient arrives with a dental abscess needing urgent care. The receptionist promptly seats him in a secluded operatory rather than leaving him waiting in the crowded reception area.
Mistake to avoid: Automatically cancelling every ill patient's appointment without first considering whether the dental condition is urgent.
Supporting reference: [13]
Mandatory reporting and health privacy
36. Self-reporting cannot wait for annual renewal
Dentists must disclose to RCDSO, as soon as possible, findings of negligence or malpractice, guilty findings, charges for any offences, bail conditions or restrictions and variations, and relevant findings by other regulatory bodies. Annual licence renewal is not a reason to delay disclosure.
Worked example: A dentist is charged with an offence in September, months before renewal season. He notifies the RCDSO promptly by email rather than saving the disclosure for the annual renewal questionnaire.
Mistake to avoid: Assuming self-reporting is required only after a conviction, ignoring that charges themselves are reportable events.
Supporting reference: [16]
37. Misconduct-related employment action triggers reporting
When a dentist ends a regulated health professional's employment or restricts their privileges because of professional misconduct, incompetence or incapacity, a written report must go to that practitioner's college registrar within 30 days. The duty also covers dissolved partnerships and survives resignation or voluntary relinquishment.
Worked example: Dr. Chen revokes an associate's privileges over documented incompetence; the associate resigns first, but Dr. Chen still files a written report with the associate's college registrar within 30 days.
Mistake to avoid: Treating an associate's voluntary resignation as removing the duty to file the written report.
Supporting reference: [16]
38. Sexual-abuse reporting separates duty from patient identification
Reasonable grounds, obtained while practising dentistry, that another regulated professional sexually abused a patient require reporting to the appropriate registrar within 30 days, or immediately if abuse of that patient or other patients is reasonably anticipated. Make reasonable efforts to advise the patient of the duty to report; the report cannot be anonymous, and the patient's name requires written consent.
Worked example: A patient discloses abuse by a hygienist but refuses written consent to naming. The dentist explains the reporting duty, then files a non-anonymous report with the hygienist's college registrar, omitting the patient's name.
Mistake to avoid: Treating the patient's refusal to consent to name disclosure as cancelling the reporting duty entirely.
39. Suspected child abuse requires immediate reporting
Dentists must immediately report suspected abuse or risk of harm to a child to a children's aid society. Stated concerns include harm arising from neglect, abandonment, failure to supervise and protect, sexual exploitation and molestation, and failure to obtain required treatment.
Worked example: A child's injuries and inconsistent account raise genuine suspicion during a dental visit, so the dentist reports promptly to the children's aid society without waiting for confirmation.
Mistake to avoid: Delaying the children's aid society report until a confirmed diagnosis of abuse exists.
Supporting reference: [16]
40. Lost controlled substances have a specific reporting route
When a dentist discovers a controlled substance has been lost or stolen from the office, the RCDSO reporting page requires a report to the Office of Controlled Substances, Federal Minister of Health, within 10 days; this applies to controlled substances, not every inventory discrepancy.
Worked example: An inventory check reveals that stock explicitly identified as a controlled substance is missing from the office; the dentist reports the loss to the Office of Controlled Substances within 10 days of discovering it.
Mistake to avoid: Recording the loss only in an internal incident note without reporting through the specified federal route.
Supporting reference: [16]
41. Privacy breaches require containment and individual notification
A dental custodian must act immediately upon learning of a privacy breach, contain further exposure, and notify affected individuals at the first reasonable opportunity, explaining the breach, the response, the right to complain to the IPC, and a contact for assistance.
Worked example: After a chart is faxed to the wrong dental office, the custodian requests its secure return or deletion, checks whether copies were made, and notifies the affected patient at the first reasonable opportunity.
Mistake to avoid: Waiting for a completed investigation before starting containment of the exposed information.
Supporting reference: [23]
42. IPC breach reporting depends on specified triggers
Notify the IPC at the first reasonable opportunity when a trigger applies: unauthorized use or disclosure by someone who knew or should have known it was impermissible, theft (except encrypted or de-identified information), further unauthorized use, a pattern, disciplinary events, or significance; patient notification is separate.
Worked example: Several similar misdirected letters over months reveal a recurring process failure; the custodian reports the pattern to the IPC rather than treating each accidental disclosure as isolated, and separately notifies affected individuals.
Mistake to avoid: Assuming an accidental breach can never require IPC reporting, or checking only deliberate misconduct.
43. Serious-harm disclosure is a permission requiring judgment
Health professionals, including dentists, may disclose personal health information when they believe disclosure is necessary to eliminate or reduce a risk of serious bodily harm or death; this is a professional-judgment decision, not an automatic mandatory reporting duty.
Worked example: A patient's statement raises a credible risk of serious bodily harm to another person; the dentist assesses whether limited disclosure is necessary and consults legal counsel before acting.
Mistake to avoid: Treating this permission as unlimited authority to share a patient's entire record.
Supporting reference: [16]
Patient records and continuity
44. Record entries must be dated and attributable
Record entries should be complete, clear, legible, dated, and attributable to the treating clinician; paper entries use permanent ink or typing, while electronic entries must use an acceptable format and be locked on their attributed date.
Worked example: A clinical note accurately describes an extraction but names no author; the dentist adds proper clinician attribution through the record system's appropriate process.
Mistake to avoid: Assuming a shared office login establishes which clinician provided the treatment.
Supporting reference: [7]
45. Relevant medical history must precede treatment
Before initiating treatment, dentists must obtain all necessary and relevant medical information, covering cardiovascular and immune conditions, allergies, current medications with dosages, past hospitalizations or serious illnesses, and pregnancy or breastfeeding. The history must be updated regularly and adapted to the practice.
Worked example: A returning patient mentions starting a new medication that the chart does not list; the dentist updates the medical history and assesses its relevance before providing any treatment.
Mistake to avoid: Treating a questionnaire completed years ago as permanently current without any regular update.
Supporting reference: [7]
46. The initial odontogram is a permanent baseline
Once completed, the initial odontogram permanently records the patient's initial conditions and must not be altered. Later findings belong in written entries or a separate odontogram, and electronic systems should preserve all previous versions of any record with associated metadata.
Worked example: At a recall visit, a tooth shows new decay; the dentist records a dated subsequent finding in the written record rather than changing the initial odontogram.
Mistake to avoid: Erasing the initial odontogram entries so the chart reflects only present-day conditions.
Supporting reference: [7]
47. Radiographs need individual justification and interpretation
Radiographs require individual justification and optimization under the ALARA principle. For new patients, obtain recent images when possible, assess them alongside a clinical examination, then prescribe radiographs only if indicated, using clinical judgment. Diagnostic aids must be dated, matched to the correct patient by name, and interpreted in the record.
Worked example: A new patient supplies recent radiographs from a previous provider; the dentist reviews those images together with the clinical examination before deciding whether any additional images are individually indicated.
Mistake to avoid: Prescribing a standard full-series image package for every new patient without individual assessment.
Supporting reference: [7]
48. Treatment changes need reasons and patient decisions
As treatment progresses, document any changes to the original plan with their reasons, such as a change in diagnosis or patient preference. Record the consent conversation, the information provided including material risks and side effects, and the patient's decision, since consent is renewed throughout treatment.
Worked example: After further discussion, a patient chooses a less invasive alternative; the dentist documents the revised plan, the reason for the change, the risks discussed and the patient's decision.
Mistake to avoid: Altering the treatment plan in the chart without recording reasons or the consent discussion.
49. Requested record copies can exceed a routine transfer summary
Patients may request copies of their complete dental record; a routine continuity summary does not replace a complete-file request. With proper signed authorization, provide the requested copies—good-quality electronic or digitized versions are permissible when the recipient prefers that format—ordinarily retaining the originals.
Worked example: A former patient signs a written direction asking for her complete file, including photographs, study models and correspondence; the practice sends copies of everything requested rather than only a brief treatment summary.
Mistake to avoid: Denying a complete-file request because the practice prefers to keep records in digital format.
Supporting reference: [15]
50. Record transfers cannot be held hostage to disputes
Transfers must occur within a reasonable time; the College's usual expectation is one to two weeks from receipt of the request, though this is not an inflexible deadline for every situation. Outstanding balances and practitioner disputes must not delay access or compromise ongoing care.
Worked example: A patient owing an unpaid balance asks for records to continue care elsewhere; the office arranges transfer within about two weeks and pursues the account separately through its collection protocols.
Mistake to avoid: Refusing to release requested copies until the patient first settles an outstanding account balance.
Supporting reference: [15]
Financial conflicts and advertising
51. A perceived financial conflict can be sufficient
A conflict of interest exists when a reasonable person could conclude that financial interests—yours, a family member's, or a controlled corporation's—may influence your professional judgment. Actual compromised judgment need not be proven; routing a benefit indirectly does not avoid the conflict.
Worked example: A dentist's spouse-controlled company receives the payment from a referral arrangement; because the benefit flows to a controlled corporation, a reasonable person could still perceive the dentist's judgment as influenced.
Mistake to avoid: Judging conflicts solely by whether the dentist personally admits that his judgment was actually influenced.
Supporting reference: [10]
52. Referral benefits differ from professional earnings
Dentists may profit from providing professional services to patients, but the conflict guideline prohibits obtaining additional benefits from referring patients, from purchasing or selling dental appliances, and from purchasing, selling or supplying drugs; keep ordinary service earnings distinct from these transaction-based benefits.
Worked example: A denture manufacturer offers a dentist fifty dollars for every patient directed to its appliances; the dentist declines, recognizing the payment as a prohibited referral benefit rather than legitimate professional income.
Mistake to avoid: Assuming any revenue stream is acceptable simply because the practice may already earn professional income.
Supporting reference: [10]
53. Billings-based rent is prohibited fee splitting
Rent for premises or equipment must not be calculated from a dentist's billings, because that constitutes prohibited fee splitting; income sharing is permitted only with the guideline's specified professional arrangements, never with an ordinary commercial landlord.
Worked example: A dentist signs a lease paying the landlord 8% of monthly collections; the arrangement must be renegotiated to a fixed rent unrelated to billings.
Mistake to avoid: Relabelling billings-based payments as rent to evade the fee-splitting prohibition.
Supporting reference: [10]
54. An owned laboratory requires more than disclosure
Using a laboratory in which the dentist or family holds a financial interest requires prior disclosure, an appliance meeting professional standards, and a cost equal to an independent laboratory's charge; disclosure alone never suffices. This includes in-house CAD-CAM milling and three-dimensional printing.
Worked example: A dentist discloses her sister's laboratory ownership before treatment; the appliance charge is $300 while an equivalent appliance from an independent laboratory would cost $250, so the inflated appliance charge remains unacceptable despite disclosure.
Mistake to avoid: Comparing a total crown bill including professional fees with a laboratory-only appliance charge.
Supporting reference: [10]
55. Reduced service fees differ from referral incentives
Reduced-fee or free dental services may be offered to new or existing patients or groups such as seniors or students, but never as rewards for referring patients, and promotional gifts, gift cards, contests, prizes, rebates or credits remain prohibited.
Worked example: A practice offers seniors discounted whitening, which is permissible, but cannot offer free whitening only to patients who recruit a new patient.
Mistake to avoid: Offering free care conditional on patient referrals because the reward is dental treatment.
Supporting reference: [10]
56. Advertising must remain controlled and factually verifiable
Professional advertising covers websites, signage and any material produced by others on the dentist's behalf, so dentists must personally control it and avoid misleading, unverifiable, comparative or superiority statements and promises of favourable results.
Worked example: A marketing agency drafts a website promising every patient an ideal smile; the dentist must remove that outcome promise before the site goes live.
Mistake to avoid: Delegating advertisement writing to an agency and assuming professional truthfulness rules no longer apply.
Supporting reference: [11]
57. Advertising disclosures must clarify status and price
An advertisement referencing an area of practice, procedure or treatment must clearly disclose registration as a general practitioner or specialist, naming the specialty if applicable. Advertised fees must be clearly stated and, unless otherwise specified, are maximum inclusive fees, including laboratory costs, applicable to all patients.
Worked example: A general practitioner's website advertises a treatment at $1,800, clearly stating any excluded services and identifying her general-practitioner status; the stated fee applies even to a patient who never saw the advertisement.
Mistake to avoid: Omitting registration status or reserving an advertised fee only for patients who mention the advertisement.

Practice ownership and liability protection
58. Ownership changes must preserve patient information and choice
Wherever possible, the dentist leaving the practice shall notify patients in writing of an ownership change within a reasonable time. If the outgoing dentist cannot notify them, such as after death, the incoming dentist shall notify patients in writing of the circumstances and that the records are in his or her possession. A dentist must take professional responsibility for patient charts. Where the treating relationship ends, the Managing Conflicts standard's continuity-of-care notification also applies, and sale agreements should permit seller record access for legal reasons without restricting patients' choice of dentist or access to their records.
Worked example: After a dentist dies, the purchasing dentist writes to patients explaining the ownership change, confirming their records are in his or her possession, and identifying who will take over their care as custodian.
Mistake to avoid: Assuming a sale agreement's ownership transfer automatically notifies patients of the change.
59. Corporate and practice-address changes have different notices
The ownership advisory treats these as separate College notifications: a change of shareholders in a dentistry professional corporation, with required documentation, must be reported within 10 days of the change taking place, while any change in the address of a member's practice of dentistry must be reported within 30 days.
Worked example: A corporation adds a new shareholder in March and relocates the practice in June; the College receives shareholder notice within 10 days and the address-change notice within 30 days.
Mistake to avoid: Using the 30-day address deadline for reporting a professional corporation's shareholder change.

60. Liability protection has occurrence and aggregate limits
For 2026, the RCDSO PLP FAQ states that Navacord operates the program from January 1, 2026, offering $2 million per occurrence and a $6 million annual aggregate cap per dentist, with lifetime tail coverage for retirement, relocation out of Ontario or death. Beginning in 2027, dentists must renew professional liability coverage directly through Navacord. Policy terms determine actual coverage; the published limits do not establish that every loss or allegation is insured.
Worked example: In 2026, three distinct covered occurrences each cost $1.8 million: each is below the $2 million per-occurrence limit, and $5.4 million total is below the $6 million aggregate if no other amounts count toward it.
Mistake to avoid: Treating the $6 million annual aggregate as available for each single occurrence.
