Disputing a dental bill in Canada: overcharges, surprise fees and Quebec's fee conciliation

If a dental bill is higher than you agreed or includes charges you do not understand, start by asking the office for an itemised bill with procedure codes and comparing it with your written estimate and your insurer's statement. Most disagreements are resolved at this stage. If not, put your concern in writing. In Quebec, the Ordre des dentistes du Québec runs a formal fee conciliation and arbitration process: you generally have 60 days from receiving the account to ask for conciliation, and 30 days after the syndic's conciliation report to request arbitration. In other provinces, billing that raises a conduct issue (for example charging for services not provided) can go to the regulator, while ordinary price disagreements usually end in negotiation or small claims court.

This guide is part of the dental complaints in Canada overview. It describes general steps, not legal advice.

Common reasons a bill differs from expectations

Step by step

1. Gather documents: estimate, consent forms, receipts, insurer statements (explanation of benefits), CDCP statements, appointment dates.
2. Ask for an itemised bill and an explanation. Ask calmly which lines differ from the estimate and why.
3. Check the insurer's side. If the plan paid less than expected, the issue may be with the plan, not the office. See appealing a refused implant claim.
4. Write to the office. State what you dispute, why, and what you propose (for example paying the undisputed amount now). Keep a copy.
5. Use the formal route for your province (below).
6. Pay what is not in dispute where you can, to show good faith and to avoid collection on the whole account.

Quebec: ODQ fee conciliation and arbitration

The ODQ's page on contesting fees ("contester des honoraires") describes these steps:

• Talk to your dentist first and ask for an explanation.
• Conciliation request to the Bureau du syndic if you consider the fees unfair, unreasonable or disproportionate to the services. The general deadline is 60 days from receiving the account (for unpaid or partly paid accounts). For unpaid accounts, a request can still be made after 60 days as long as you have not been served with a court claim for the account.
• Treatment in instalments: the 60 days run from the most recent account or instalment due, and the request can cover the past year.
• Insurer refusal: if RAMQ or another insurer refuses reimbursement and that decision comes more than 60 days but less than a year after you received the account, you have 30 days from the decision to apply.
• Arbitration: if conciliation does not produce an agreement, you can request arbitration within 30 days of receiving the syndic's report.

The process is about whether fees are justified. It is not designed to compensate you for harm caused by a professional fault; for that, a civil action may be needed.

Other provinces

• Regulator: if the billing suggests a professional conduct problem, such as charging for treatment not performed, not disclosing fees before treatment, or billing an insurer inaccurately, you can complain to the regulator (for example the Royal College of Dental Surgeons of Ontario, the BC College of Oral Health Professionals or the College of Dental Surgeons of Alberta).
• Small claims court: for a refund or to defend a claim for payment. Monetary limits and procedures vary by province; check your provincial court's website.
• Collections: if an account goes to a collection agency, provincial collection agency rules apply. Dispute the debt in writing.

Worked example (illustrative)

Your estimate for a crown was $1,350 (fee $950, lab $400). The bill is $1,600 with an added core build-up of $250 you say was not discussed. Your plan pays 50% of eligible fees: 50% × $1,600 = $800, within your maximum.

• Balance billed to you: $1,600 − $800 = $800
• Balance if the core had not been added: $1,350 − $675 = $675
• Disputed amount: $125 (your share of the core)

A reasonable letter would ask why the core was added and whether it was discussed, offer to pay $675 now, and ask for the treatment notes. If the dentist explains it was necessary and discussed during the visit, consider whether that matches your recollection; disputes over small amounts are often settled by agreement.

Letter outline

• Your name, date of birth, patient number
• Treatment dates and the bill in question
• The specific lines you dispute and why
• What you have paid and what you propose
• A request for a written reply within a reasonable time

FAQ

Can the dentist refuse to give me my records because of an unpaid bill?

Regulators generally expect dentists to provide patients with copies of their records, sometimes for a reasonable fee. Check your regulator's guidance; withholding records over a bill is a question to raise with them.

Can the office send me to collections while I dispute the bill?

It may. Put your dispute in writing, pay the undisputed part and, in Quebec, file for conciliation within the deadline.

What if my insurer refused to pay after I was told it would?

A predetermination is usually an estimate. Ask the insurer why and use its appeal process. In Quebec, an insurer refusal can extend the ODQ deadline as described above.

Is a lawyer necessary?

Not for most bill disputes. Consider one for large amounts or if injury is involved.
