Patient complaints alleging negligence are among the most stressful situations a dentist can face.
The process of responding to a claim can be time-consuming, emotionally draining, and reputationally concerning. A recent British Columbia case offers a helpful reminder that fundamental practice management still matters. Strong record-keeping, proper consent practices, and professionalism remain a dentist’s strongest protection.
In this post, we review what happened, how the Civil Resolution Tribunal (CRT) in British Columbia approached the allegations, and what Ontario dentists can take from the decision.
Background
In Willis v. Dr. K.G. Lim Inc., the patient, Ms. Willis, alleged that her dentist “ruined” her teeth over a long treatment relationship. She claimed that the extractions and restorative work rendered her remaining teeth non-viable and sought damages for alleged malpractice, refunds for deposits and a nightguard, and compensation for pain and suffering.
The dentist denied negligence and maintained that the treatment provided was appropriate given the patient’s longstanding dental condition and financial constraints. He relied on his records that documented nearly two decades of care.
The Issues
At its core, the Tribunal was asked to decide whether the dentist:
- Breached the applicable standard of care, and
- Caused the patient harm through negligent treatment or improper billing practices.
The Decision
Ultimately, the Tribunal dismissed the patient’s claim in its entirety.
It found that the patient failed to meet the burden of proving professional negligence. She provided no expert evidence, no independent dental records, and no objective proof that the dentist’s work fell below professional standards.
The Tribunal also rejected the patient’s claims relating to deposits, consent, and the nightguard, finding the dentist’s explanations reasonable and supported by his records.
Why Does This Matter?
This decision reinforces several principles that are particularly relevant to practice owners managing business risks.
Allegations Are Not Evidence
For a professional negligence case to succeed, a patient must show that the dentist fell below the standard of care. In most cases, that requires expert evidence. Here, the Tribunal emphasized that dissatisfaction with outcomes or distrust of providers is not evidence of negligence.
For dentists, this case is an important reminder that dissatisfaction or complaints alone do not automatically translate into liability.
The Importance of Longitudinal Records
One of the dentist’s strongest assets in this case was his complete patient ledger, documenting nearly 20 years of care. Those records demonstrated:
- The patient’s longstanding dental deterioration
- The clinical reasoning behind conservative treatment choices
- The financial realities influencing treatment planning
- The durability and history of restorations over time
The Tribunal accepted the dentist’s explanation that crowns may have been ideal but were financially out of reach, and that interim restorations were a reasonable and professional alternative.
From a business risk perspective, records function as long-term protection, not just clinical documentation.
Consent and Authorization Are Judged on Reasonableness
The patient argued that she had not specifically authorized deductions from her deposit for preliminary repairs and x-rays. With this claim, the Tribunal took a pragmatic view. It found that the patient had authorized the work itself, and that it was reasonable for the dentist to apply part of the deposit to services actually rendered. Also, when the insurer ultimately declined coverage for the proposed treatment, the dentist refunded the remaining balance.
This illustrates an important distinction: consent does not require perfection, but it does require good judgment and transparency. Dentists should ensure that deposits, estimates, and billing authorizations are clearly explained and documented—but also take comfort that tribunals recognize practical realities.
Delay Affects Credibility
Another notable aspect of the decision involved the nightguard. The patient complained about the fit three years after delivery. The dentist’s records showed it fit when provided, and there was no evidence suggesting it was defective or unreasonably short-lived.
The Tribunal placed weight on the delay and the absence of supporting evidence. Accurate records of delivery, fit checks, and follow-up discussions proved decisive.
Professionalism in the Face of Conflict
Perhaps most importantly, the dentist’s response helped his credibility. Throughout the dispute, the dentist maintained a measured and professional approach; he did not over-argue, disparage the patient, or adopt a defensive tone. He relied on records, explained his clinical reasoning, and refunded money when appropriate.
That approach aligns with expectations placed on Ontario dentists by the RCDSO: professionalism, transparency, and patient-centred communication.
Bottom Line
This case serves as a timely reminder that solid fundamentals remain the best risk management strategy in dental practice. Good records, reasonable business practices, good judgment and professionalism work. When those elements are in place, even serious allegations can be successfully defended.
