What CDCP Actually Covers in 2026: A Dentist's Honest Guide

Last updated 2026-05-23. Fact-checked against Canada.ca, Sun Life CDCP benefit grids, and the April 2026 preauthorization update.

If you've been approved for CDCP, here's what's actually in scope and the 6 things that aren't. The official coverage page doesn't make this easy to find, so we mapped it against the Sun Life dental benefit grids procedure-by-procedure. The 2026 benefit year has two important changes: all ages are now eligible, and starting April 1, 2026, every desensitization service requires preauthorization.

Key Takeaways

• CDCP covers 8 broad service categories: diagnostic, preventive, restorative, endodontic, periodontal, removable prosthodontic (dentures), oral surgery, and sedation.
• CDCP does NOT cover: dental implants and implant-supported dentures, cosmetic procedures (whitening, veneers), adult orthodontics, night guards, sports mouthguards, and restorations for incisal wear.
• Limited orthodontic services are "coming at a date to be determined" -- no firm 2026 timeline as of this update.
• Co-pay scales with income: 0% under $70K, 40% at $70-79.9K, 60% at $80-89.9K. $90K+ is not eligible.
• April 1, 2026 update: All desensitization services now require preauthorization before billing.

What CDCP covers (the 8 service categories)

The plan organizes covered care into eight categories. Within each, some services are covered without preauthorization (you can book them and your dentist bills CDCP directly) and others require preauthorization (your dentist submits the proposed treatment to CDCP first; you proceed only after approval).

Category	What it includes	Preauthorization typically required?
Diagnostic	Exams, x-rays, oral health assessments, consultations	Routine exams: no. Specialist consults and advanced imaging beyond frequency limits: yes.
Preventive	Cleanings, scaling, polishing, fluoride, sealants	Within frequency limits: no. Above-limit (extra scaling for periodontal patients, etc.): yes.
Restorative	Fillings (composite and amalgam), some basic crowns	Standard fillings: no. Multi-surface complex restorations: sometimes.
Endodontic	Root canal treatment by tooth type (anterior, bicuspid, molar)	Molar root canals beyond a cost threshold: yes. Anterior usually: no.
Periodontal	Scaling, root planing, gum-disease treatment	Frequency-limited; above-limit: yes.
Removable prosthodontic	Complete dentures, partial dentures, relines, repairs	New dentures: yes (always). Reline and repair: typically no.
Oral surgery	Simple and surgical extractions, including most wisdom teeth	Surgical and impacted extractions: yes. Simple extractions: no.
Sedation services	Sedation and pain management during procedures	Yes, in most cases.

What CDCP does NOT cover (the honest list)

This is the disclosure most CDCP marketing skips. Knowing what's excluded matters as much as knowing what's covered, because the gap is often where patients get blindsided with out-of-pocket costs.

1. Dental implants and any implant-supported dentures. Both the implant placement and any prosthetic that attaches to an implant are excluded. Bone grafts associated with implant work are also excluded. This is the single biggest exclusion by patient demand.
2. Cosmetic procedures. Teeth whitening (in-office or take-home), porcelain veneers, elective bonding for aesthetics, gum contouring. Anything done primarily to change appearance rather than restore function.
3. Adult orthodontics, including Invisalign and traditional braces. Adult ortho is excluded. Limited orthodontic services for children with severe malocclusion are scheduled to become available "at a date to be determined" -- as of May 2026 there's no firm start date.
4. Night guards (occlusal splints for bruxism). If you grind your teeth and your dentist recommends a custom night guard, CDCP doesn't cover it.
5. Sports mouthguards. Custom athletic mouthguards are out of scope.
6. Restorations for incisal wear involving enamel and dentin. These are formally listed in the CDCP exclusions appendix and are not eligible for reconsideration.

If a treatment falls in one of these categories, your dentist is allowed to provide it -- but you'll pay out of pocket, and the dentist must explain this in writing before doing the work. CDCP exclusions are not "we'll appeal it for you" situations. They are hard exclusions in the Dental Benefits Guide.

The 5 things people miss

These are the rules patients consistently learn the hard way. None of them are hidden; all of them are easy to skip when reading the program docs.

1. The CDCP fee schedule is federal, not provincial. Your dentist might bill privately at the Ontario Dental Association suggested fee guide, which is higher than the CDCP federal schedule. If they choose to charge above the CDCP rate for a covered service, they need your written consent first and you pay the difference. A well-run practice explains this on day one. 2. "Covered" doesn't always mean "100% covered." Even at the 0% co-pay bracket (under $70K income), CDCP pays its federal fee schedule amount, not necessarily what the dentist would normally charge. Most participating dentists accept the schedule as full payment. Some don't. Ask before treatment. 3. Preauthorization isn't optional for major services. Crowns, complex root canals, surgical extractions, new dentures, and as of April 2026 all desensitization services need preauthorization. If your dentist proceeds without it, the claim can be denied and you're responsible for the bill. 4. The frequency limits matter. CDCP limits how often you can have certain services (cleanings, exams, x-rays). A standard cleaning is typically covered every 9 to 12 months. If you've had one elsewhere recently, your next one may be denied or require preauthorization. 5. Direct billing is the participating-dentist standard. You should not be paying upfront and waiting for reimbursement at a CDCP-participating practice. The dentist's office bills Sun Life directly; you pay only your co-pay share. If a practice asks you to pay full and submit yourself, they're not handling it the standard way.

How co-pay actually works

Your share of CDCP-eligible costs depends on your adjusted family net income (AFNI) from your most recent tax return -- the 2025 NOA for the 2026-27 benefit year.

Adjusted family net income	Your co-pay	CDCP pays
Under $70,000	0%	100% of federal fee schedule
$70,000 -- $79,999	40%	60% of federal fee schedule
$80,000 -- $89,999	60%	40% of federal fee schedule
$90,000+	Not eligible	--

Co-pay is calculated against the federal CDCP fee schedule, not against the practice's private fee. If a covered service costs $100 on the CDCP schedule and your dentist accepts that as full payment, your bill at the 40% bracket is $40. If the dentist charges $120 with your written consent for above-schedule fees, you owe $40 plus the $20 differential.

For exact dollar examples by income bracket on a cleaning, filling, crown, and denture, see the CDCP co-payment calculator with worked examples.

Preauthorization, in plain English

Preauthorization is CDCP's review process for treatments that need approval before they happen. The workflow:

1. Your dentist examines you and recommends a treatment in a category that requires preauthorization.
2. Your dentist's office submits the proposed treatment, supporting clinical evidence (x-rays, intra-oral photos, periodontal charting), and the requested fee codes to CDCP through Sun Life.
3. CDCP reviews the submission against the Dental Benefits Guide criteria and your oral health history.
4. CDCP approves, requests more info, modifies the approved scope, or denies.
5. You and your dentist receive the decision in writing.
6. Treatment proceeds (or you appeal the denial, if appealable).

Turnaround is typically 7-21 days. For non-urgent treatment, build the wait into your booking timeline. For urgent treatment, your dentist can flag urgency in the submission.

As of April 1, 2026, all desensitization services billed to CDCP require preauthorization. This is a relatively narrow category (treating tooth sensitivity with desensitizing agents or laser) but the change caught a lot of practices off-guard in April 2026. If your treatment plan includes desensitization, expect a short delay.

From Dr. Kaur

"The most common surprise I see is the implant-supported denture exclusion. A patient comes in for new dentures, qualifies under CDCP, and then we discover the existing implants need new attachments or the patient wanted implants placed before the denture. Implants are a hard no under CDCP and there's no appeal route. We spend the first appointment redesigning the treatment plan around traditional removable dentures, which CDCP does cover.

If you're at the stage of planning new dentures and considering implants, get that decision sorted before you apply CDCP to the case. Otherwise you're back to a different conversation."

Frequently Asked Questions

Does CDCP cover wisdom tooth removal? Yes, in most cases. Simple extractions are covered without preauthorization. Surgical and impacted wisdom tooth extractions are covered with preauthorization. Your dentist submits the radiographs and clinical findings; CDCP approves on medical-necessity criteria. Does CDCP cover cleanings every 6 months? Frequency limits typically allow a cleaning every 9 to 12 months for adults at average risk. Higher-frequency cleanings (every 3-6 months) for patients with active periodontal disease or other specific clinical reasons can be approved through preauthorization. Does CDCP cover dental implants? No. Implants and implant-supported dentures are excluded under the Dental Benefits Guide. There is no appeal mechanism for this exclusion. Does CDCP cover Invisalign or braces? Adult orthodontics is not covered. Limited orthodontic services for children with severe malocclusion are scheduled to become available "at a date to be determined" with no firm 2026 start date. See CDCP and Invisalign for the full breakdown. Does CDCP cover sedation for dental procedures? Yes, sedation and pain management services are in scope. Most sedation services require preauthorization. The level of sedation covered (oral, nitrous, IV) depends on the procedure and clinical need. Does CDCP cover root canals on molars? Yes, with preauthorization above a cost threshold. Anterior tooth root canals are usually covered without preauthorization. Molar root canals are more complex and almost always preauthorized. See root canal coverage by tooth type for specifics. Can my dentist charge me above the CDCP fee? Only with your written consent before treatment. Reputable participating practices accept the CDCP federal fee schedule as full payment for covered services. If a practice wants to bill above-schedule, you're entitled to a clear written estimate first. What if a service I need is denied or excluded? Denied services (where you and your dentist disagree with CDCP's decision) can be appealed through the reconsideration process. Excluded services (in the Dental Benefits Guide's Appendix E) cannot be appealed -- they are hard exclusions.

Bottom line

CDCP covers 8 broad service categories at a federal fee schedule that's paid in full at the 0% co-pay bracket (income under $70,000). Co-pay rises to 40% at $70-79,999 and 60% at $80-89,999. Six categories are hard-excluded: implants, cosmetics, adult orthodontics, night guards, sports mouthguards, and incisal-wear restorations. Major services (crowns, dentures, complex extractions, molar root canals, sedation, and as of April 2026 all desensitization) require preauthorization. A participating dentist direct-bills Sun Life; you pay only your co-pay share. Knowing what's excluded matters as much as knowing what's covered.
