How does the CDCP work for dental care once your coverage is active and you are ready to book? Having your Sun Life member information does not automatically tell you what a visit will cost, who submits the claim, or whether a planned treatment needs approval first. Those details are where most of the confusion starts. The process is easier to follow when you separate four things: your active coverage, the CDCP-established fee, your income-based co-payment, and any preauthorization requirement. This guide follows the billing process at a Toronto dental office from booking through checkout so you can understand what the clinic does, what Sun Life decides, and what may remain your responsibility.
How Does the CDCP Work for Dental Care Once Coverage Is Active?
In practical terms, how does the CDCP work for dental care at a dental office? The sequence usually looks like this:
- The office confirms your CDCP information and active coverage.
- The dentist assesses what care is clinically needed. Coverage does not decide treatment.
- The proposed services are checked against current CDCP rules, including frequency limits and preauthorization requirements.
- Expected patient costs are reviewed when enough information is available.
- The provider submits eligible claims to Sun Life.
- Sun Life adjudicates the claim and pays the provider for the covered portion.
- You pay the applicable co-payment and any legitimate amount outside CDCP coverage.
CDCP members do not submit their own claims for reimbursement. If you pay the full cost of covered treatment yourself, Sun Life does not reimburse you directly.
If you are still trying to locate or confirm a participating office rather than understand the billing process, Market Dental Centre's guide to finding a CDCP dentist in Toronto covers that separate question.
Your Member Card Is Not a Treatment Estimate
Your CDCP member card or member information identifies you to the program, but active coverage still needs to be confirmed for the date of service.
It is useful to have your member information, identification, and welcome or coverage information available when you contact the clinic. Your benefit effective date and co-payment level are part of your coverage details, but neither tells you what treatment you need or guarantees that every proposed service will be covered.
From Booking to Checkout: The CDCP Claim Flow

At a Toronto dental office, the administrative process becomes much easier to follow when each step has a clear owner.
An electronic estimate can be useful before treatment, but it is not the same thing as CDCP preauthorization. An estimate can help indicate expected benefits for services that do not require prior approval. Preauthorization is a formal coverage requirement for specific services.
Electronic claim responses are often fast, but they should not be described as guaranteed or instant. A claim can require additional review or supporting information before the final covered amount is known.
That is one of the most useful answers to how does the CDCP work for dental care: the clinic submits the claim, Sun Life adjudicates it, and payment for the covered portion goes to the provider.
What the 0%, 40% and 60% CDCP Co-Payments Mean

Your co-payment level is based on adjusted family net income.
The percentage applies to the CDCP-established fee for an eligible service. It is not a percentage of whatever fee a dental office happens to charge.
So, how does the CDCP work for dental care if your co-payment is 40%? If an eligible service has a CDCP-established fee of $100, the program portion is $60 and your income-based co-payment is $40.
A 0% co-payment does not mean every possible dental service will cost $0. A service may be excluded, fall outside a frequency limit, fail to meet program criteria, or require preauthorization that has not been approved.
CDCP Balance Billing: The Fee Difference Is Separate From the Co-Payment

The CDCP has its own established fees. These are separate from provincial fee guides, including the Ontario Dental Association Suggested Fee Guide.
The ODA guide is a reference, not a mandatory Ontario price list. Dental offices determine their own fees.
Under the general CDCP framework, a provider may charge more than the CDCP-established fee. When that happens, the difference can become an additional patient charge on top of any income-based co-payment.
Market Dental Centre has a clinic-specific policy that changes this calculation. For eligible services covered under the CDCP, the clinic follows the CDCP-established fee and does not add a separate clinic markup above that amount.
That does not change the federal coverage rules. A patient can still owe a co-payment or an amount for care that falls outside CDCP coverage.
A Simple Patient-Cost Formula
General CDCP Framework
Patient co-payment
- any provider charge above the CDCP-established fee
- any non-covered or outside-program amount
= potential patient amount
At Market Dental Centre for an Eligible CDCP-Covered Service
Patient co-payment
- any legitimate non-covered or outside-program amount
= potential patient amount
There is no separate clinic markup above the CDCP-established fee for that eligible covered service.
This is why how does the CDCP work for dental care cannot be answered from the 0%, 40% or 60% number alone. You also need to know whether the service is eligible and whether program limitations apply.
A $100 Example Without Inventing a Dental Fee
Hypothetical example only. This is not a Market Dental Centre fee.
Assume an eligible service has a CDCP-established fee of $100.
Now suppose another provider charges $115 for that same service. Under the general CDCP framework, there could also be a $15 difference between the provider's fee and the CDCP-established fee.
At Market Dental Centre, that separate $15 clinic difference would not be added for an eligible covered service because the clinic follows the CDCP-established fee.
A separate service that CDCP does not cover would still sit outside this calculation.
Preauthorization: When Sun Life Must Approve Coverage Before Treatment

How does the CDCP work for dental care when a service requires approval first? The process is called preauthorization.
Preauthorization is a coverage decision. It does not determine whether treatment is clinically appropriate. The dentist and patient make the treatment decision; Sun Life evaluates whether the requested service meets current CDCP coverage criteria.
When preauthorization is required, approval generally needs to be in place before treatment begins for that service to qualify for CDCP coverage. Post-determination is reserved for limited emergent situations.
The dental office submits the request and supporting information. Depending on the service, that can include a treatment plan, radiographs, periodontal charting or clinical notes.
Processing time varies. There is no reliable universal promise such as “two to four weeks.”
Most preauthorization decisions remain valid for up to 12 months as long as the patient remains eligible when treatment is provided. Some preventive and periodontal preauthorizations can remain valid for up to 24 months.
If a request is denied, the current program provides one level of reconsideration. The provider must submit the reconsideration request within 60 days and include new or additional supporting clinical information.
The current requirements are detailed in the Government of Canada CDCP Dental Benefits Guide.
Which Services Need CDCP Preauthorization in 2026?
Not every dental service follows the same approval path.
Two points are especially easy to get wrong:
- Standard root canal treatment on first and second molars does not currently require preauthorization.
- Not every surgical extraction or oral surgery procedure requires preauthorization. The procedure code and current benefit grid determine the requirement.
Current CDCP exclusions include implant and implant-related procedures, fixed bridges, inlays and onlays, composite or ceramic veneers, cosmetic teeth whitening, and bruxism appliances such as night guards. Orthodontic services are currently not available under the program.
What an Explanation of Benefits Tells You

An Explanation of Benefits (EOB) is Sun Life's response showing how a submitted claim or estimate was processed.
Depending on the claim, it may show:
- the submitted service
- the eligible amount recognized under CDCP rules
- the amount payable to the provider
- the applicable patient co-payment
- messages about limits, reductions or additional information
The dental office's own statement or receipt can then show any clinic charges or services outside CDCP coverage.
An EOB is useful because it separates two different questions: “What treatment did the dentist recommend?” and “What amount did the CDCP recognize and pay?”
For someone asking how does the CDCP work for dental care after treatment, the EOB is one of the clearest records of how Sun Life processed the claim.
Can You Use the CDCP With Other Dental Coverage in Ontario?
Private dental insurance is relatively straightforward: people with access to qualifying private or employer dental coverage are generally not eligible for the CDCP, so the two systems do not coordinate.
Government social dental programs are different.
For Healthy Smiles Ontario and ODSP coordination, provincial schedules can supplement the CDCP payment under Ontario's rules. When those schedules are being used to coordinate payment, balance billing the patient for the remaining fee difference is not permitted.
Program frequency limits are not simply added together.
Market Dental Centre's guide to CDCP vs private dental insurance in Ontario provides more background if you need to compare the two systems.
Five CDCP Billing Assumptions Worth Correcting
“My Co-Payment Is 0%, So Every Treatment Is Free.”
No. A 0% co-payment means the CDCP pays 100% of its established fee for an eligible covered service. Exclusions, frequency limits and other non-covered care can still create a patient cost.
“I Can Pay the Whole Dental Bill and Claim It Back From Sun Life.”
No. CDCP claims are submitted by oral health providers for direct payment. Members do not submit their own claims for reimbursement.
“If My Dentist Recommends a Crown, CDCP Automatically Covers It.”
No. Eligible single-unit crowns require preauthorization and must meet current clinical and program criteria.
“Every Root Canal Needs Approval Before Treatment.”
No. Standard root canal treatment on anterior teeth, bicuspids, first molars and second molars generally does not require preauthorization. Re-treatment and certain other endodontic procedures do.
“My CDCP Card Tells the Office What Treatment I Am Entitled To.”
The card identifies your program membership. Clinical need comes from the dental examination, and coverage is then assessed under the program's rules.
Three Questions to Ask Before Planned Treatment
You do not need an insurance script. These three questions cover most of the practical uncertainty:
- Which parts of this treatment plan are eligible under my current CDCP coverage?
- Does anything require preauthorization before treatment starts?
- Based on the information available now, what patient amount should I expect?
The final amount can still change if your coverage status, program rules, fees or clinical treatment plan changes before care is provided.
For a first visit in Downtown Toronto, a general dental examination can establish what care is actually needed before CDCP rules are applied to the treatment plan.
How Does the CDCP Work for Dental Care at Market Dental Centre?

Market Dental Centre is located at 149 Lower Jarvis Street in Downtown Toronto, Ontario, near St. Lawrence Market. The clinic provides CDCP direct billing for eligible services.
The clinic's confirmed fee approach is straightforward: for eligible CDCP-covered services, Market Dental Centre follows the CDCP-established fee without adding a separate clinic markup above that amount.
The federal program rules still apply. The office can help confirm administrative information and submit claims, but Sun Life determines the covered amount under the CDCP and the dentist determines what treatment is clinically appropriate.
Toronto patients who want a broader explanation of claims can review Market Dental Centre's guide to direct billing versus reimbursement. The clinic's CDCP information page also covers current patient information.
Key Takeaways
- The CDCP pays eligible covered amounts to oral health providers, not to members.
- Coverage should be active on the date care is received.
- The 0%, 40% and 60% co-payment levels apply to the CDCP-established fee.
- A 0% co-payment does not mean every possible dental service is free.
- Market Dental Centre does not add a separate clinic markup above the CDCP-established fee for eligible covered services.
- Only certain services require preauthorization. Eligible crowns do, while standard root canal treatment on first and second molars generally does not.
- Private dental coverage does not coordinate with CDCP, while some Ontario social dental programs can.
Have Active CDCP Coverage? Start With the Treatment and the Expected Patient Share
You do not need to decode the entire CDCP before making a dental appointment.
If your coverage is active, bring your member information and explain what care you need. Once a dentist has assessed the clinical issue, the office can check the relevant CDCP rules, identify whether preauthorization is required, and review the expected patient amount when that information is available.
Market Dental Centre is at 149 Lower Jarvis Street in Downtown Toronto, Ontario, near St. Lawrence Market. Call (416) 363-4115 or request an appointment with your CDCP details.
