Patients arrive at our Waterford office with a card in hand and no idea where it stops. They assume a federal plan covers everything, book a consultation about implants, and hear a number they were not expecting. The Canadian Dental Care Plan (CDCP) is a federal dental benefit that pays an established amount toward a defined list of oral health services for eligible Canadian residents without private dental insurance. The word doing the work in that sentence is defined. Knowing the list before you book is the difference between a routine visit and a surprise. Here is what the plan pays for, service by service.

Start With the Service Categories the Plan Pays For

The CDCP covers eight categories of care, and most of what a family needs sits inside them. According to the federal coverage schedule in effect as of April 1, 2026, the plan pays toward:

• Diagnostic and preventive — complete, routine, specific and emergency exams, x-rays, scaling, fluoride and sealants
• Basic restorative — permanent and temporary fillings, and pain control for diseased teeth
• Endodontic — root canals, pulpectomies and procedures that treat infection
• Periodontal — cleaning below the gumline, abscess treatment and non-surgical gum disease care
• Major restorative — cores and crowns, posts, post removal, crown repairs and re-bonding
• Removable prosthodontics — complete dentures, repairs, relines and rebases
• Oral surgery — removal of teeth and roots, surgical removal of cysts and tumours, drainage incisions and treatment of broken jaw bones
• Sedation — nitrous oxide and oral sedation

That is a genuinely broad list for anyone whose dental care has been limited to emergencies. A cleaning, an exam, a filling and a root canal are all inside it. Waterford Dental accepts CDCP patients, and our CDCP information page explains how we bill the plan directly.

Check the Exclusions Before You Plan Treatment

Five requests come up constantly, and four of them are outside the plan. The federal exclusion list is explicit:

• Dental implants — not covered. Implants and all implant-related procedures are excluded, along with ridge augmentation.
• Braces and Invisalign — not covered. Orthodontic services are not currently available under the CDCP.
• Teeth whitening — not covered. Cosmetic treatment, including whitening, is excluded.
• Night guards and sports mouthguards — not covered. Bruxism appliances are on the exclusion list.
• Crowns — covered, with a condition we cover in the next section.

If a night guard is what you need, that cost sits with you regardless of coverage, and our custom sports guards page sets out the options. The useful move is to ask which category your treatment falls into before the appointment, not after the plan is billed.

Know Which Covered Services Still Need Preauthorization

Covered does not mean automatic. A set of CDCP services requires written approval from Sun Life before treatment starts, and work done without it can be refused. Preauthorization applies to:

• crowns, cores and posts for crowns
• partial dentures, and complete immediate and overdentures
• root canal re-treatments
• bonding for mobile teeth and post-surgical evaluations
• conscious sedation, deep sedation and general anesthesia
• any service that exceeds an established frequency limit

Approval takes time, so a crown is rarely a same-week procedure under the plan. Build that into your scheduling rather than discovering it at the chair. Our guide to what the CDCP pays and what you owe walks through how an estimate is put together before treatment begins.

Watch the Frequency Limits — Coverage Is Capped by Time

The most common reason a CDCP claim is reduced is not the service; it is the calendar. Limits run on rolling periods, so the question is always how long it has been since the last one, not what year it is now.

Anything past these limits needs preauthorization. If you are unsure whether your coverage year is still active, our CDCP renewal guide explains how to confirm it.

Separate “Covered” From “Paid in Full”

A service being covered does not mean your bill is zero. Two separate rules decide what you actually pay.

The first is your co-payment, set by adjusted family net income:

The second rule catches more patients than the first. The CDCP reimburses against its own established fee schedule, which may be lower than the fee a dental office charges, and the federal plan states plainly that you may be charged for the difference where care costs more than the plan reimburses. A covered crown with a 0% co-payment can still leave a balance for this reason.

This is why a written estimate matters more under the CDCP than under most private plans. At Waterford Dental we go through the established fee, your co-payment tier and any remaining balance before treatment is scheduled — the detail is in our CDCP fee guide. Routine preventive visits are where the plan performs best, because the established fees and frequency limits line up with the preventive care schedule most families already follow.

Frequently Asked Questions

Does the CDCP cover crowns?

Yes. Crowns and cores are covered under major restorative services, with a limit of one crown per tooth every eight years. Crowns, cores and posts all require preauthorization from Sun Life before treatment starts, so the approval has to be in place first. Crown repairs and re-bonding an existing crown are also covered services.

Does the CDCP cover wisdom teeth removal?

Extractions are covered. Removal of teeth and roots falls under the plan’s oral surgery category, which also includes surgical incisions and removal of cysts. Some surgical procedures and any sedation beyond nitrous oxide require preauthorization, so confirm the specific procedure codes with your dentist before the appointment is booked.

Does the CDCP cover dentures and partial dentures?

Yes, with strict timing. Complete dentures are covered once per arch every eight years, and partial dentures once per arch every 60 months for acrylic or 96 months for cast. Initial partial denture placements require preauthorization, and precision attachment partials are excluded entirely.

Ask the Coverage Question Before You Book

The plan covers more routine care than most patients expect and less major work than they hope: cleanings, fillings, root canals, extractions, crowns and dentures are in; implants, orthodontics, whitening and night guards are out. The second question matters as much as the first — whether your treatment needs preauthorization, and whether you are still inside the frequency window.

Bring your Sun Life member number to your next visit and ask our team to check both before treatment is scheduled. Contact Waterford Dental to book a CDCP appointment, or call 519-443-0100 and we will confirm what your coverage allows.
