Why Your Dentist Can Charge More Than CDCP Covers

See your real balance-billing gap

Enter what your dentist quoted and compare it against the provincial fee-guide proxy the CDCP calculator uses, by province, income tier and procedure.

The three reasons your dentist's bill can exceed CDCP

According to the Government of Canada's own CDCP coverage page, extra out-of-pocket charges apply in three situations:

1. Your income tier includes a co-payment. At $70,000–$79,999 adjusted family net income you pay 40% of the CDCP fee; at $80,000–$89,999 you pay 60%. This co-payment applies even if your dentist charges exactly the CDCP rate.
2. Your dentist's fee is higher than the CDCP established fee. This is balance billing — it can happen at any income tier, including the 0% co-pay tier under $70,000.
3. You agreed to a service the CDCP does not cover, such as an implant, a veneer, or an upgraded material not included in the standard grid — in which case you pay the full cost.

Balance billing is the situation that causes the most confusion, because patients who make under $70,000 are told their co-payment is $0 and reasonably expect the visit to cost nothing. The CDCP's 0% co-pay only means the CDCP pays 100% of its own fee — it says nothing about what your dentist charges.

Why the gap exists: CDCP fees vs. provincial fee guides

The CDCP does not use the same fee schedule your dentist's professional association publishes. Most dentists price their services close to their provincial association's suggested fee guide (Ontario's ODA guide, Quebec's ACDQ guide, and so on), while the CDCP reimburses against its own, separately negotiated CDCP Dental Benefit Grid — which in practice tends to sit under the provincial guide amount for many procedures. That gap is what shows up as balance billing on your invoice, even when nothing about your treatment was unusual.

Our provincial cost index — the same dataset behind the calculator above — tracks these provincial guide amounts by procedure. Using a ceramic crown as an example, the provincial suggested-fee amount ranges from roughly $910 in Prince Edward Island to a $1,349–$1,449 range in Ontario, and up to $2,200 at the high end of Quebec's guide (some provincial figures are modelled estimates where the association guide isn't public — flagged as such in the dataset below). Whatever the CDCP's own crown fee turns out to be in your case, if your dentist's price sits at or near the provincial guide, expect a balance-billing gap on a partially covered procedure like a crown, where preauthorization already applies.

These are provincial suggested-fee-guide amounts, used here as a proxy for the size of the balance-billing risk — not the CDCP's own established fee, which Health Canada does not publish as an open dataset.

What's permitted — and what should raise a flag

Balance billing itself is permitted. A few related practices are not, or should prompt questions before you proceed:

Generally permitted:

• Charging above the CDCP established fee and billing you the difference.
• Requiring the patient's co-payment share and any balance-billing amount at the time of service.
• Declining to accept CDCP "assignment" (billing at the CDCP rate as payment in full) — this is a practice-level choice, not a requirement.

Worth questioning before you book:

• Being asked to pay the full covered portion upfront before the claim is submitted, without a clear explanation.
• No written pre-treatment (EDI) estimate offered for a procedure that requires preauthorization, such as a crown.
• Vague answers about whether the practice bills at the CDCP rate or above it.

Checklist: what to verify before your appointment

Bring these questions to your next CDCP appointment or ask them by phone when booking:

1. Does this practice accept CDCP assignment, or does it bill above the CDCP established fee for this procedure?
2. Can I get a written pre-treatment (EDI) estimate showing the CDCP-covered amount and my expected balance before treatment starts?
3. What is my current co-payment tier, based on my most recent Notice of Assessment income?
4. Does this procedure require preauthorization from Sun Life (crowns and initial cast partial dentures always do)?
5. What is the total I will owe, combining my income-tier co-payment and any balance-billed amount above the CDCP fee?
6. If a non-covered add-on is recommended (for example, an implant instead of a covered denture), ask for that cost separately from the CDCP-covered treatment plan.

What to do if you think you were overcharged

If a bill doesn't match what you expected, start by asking the practice for an itemized breakdown showing the CDCP-covered amount, your co-payment, and any balance-billed difference. If the numbers still don't add up, or you suspect a covered procedure was billed as though it wasn't covered:

• Call the CDCP information line at 1-833-537-4342 to confirm what the CDCP should have reimbursed for your procedure.
• Contact Sun Life at 1-888-888-8110, the CDCP's claims administrator, to request a claim review.
• Raise a billing-conduct concern with your provincial dental regulator — for example, the Royal College of Dental Surgeons of Ontario for Ontario practices — if you believe a charge was misrepresented rather than simply above the CDCP fee.

Balance billing that is disclosed upfront and matches a written pre-treatment estimate is not a billing error, even when the total feels higher than expected. The recourse paths above are for cases where the amount charged doesn't match what was disclosed, or where a covered service appears to have been billed incorrectly.
