The Canadian Dental Care Plan: What It Won't Pay and How to Plan for the Gap

The Canadian Dental Care Plan (CDCP) changed the picture for a lot of families who had been skipping the dentist. But "I'm in the CDCP" and "my dental bill is covered" are not the same sentence. Depending on your income, the treatment you need and what your dentist charges, you can still end up holding a meaningful bill.

This article is for Canadians who already qualify, or think they might, and want to know where the gaps are before they sit in the chair. We'll go through the eligibility rules, the co-payment tiers, the services that need preauthorization, what's not covered at all, and how to plan for the part the plan won't pay.

Quick Eligibility Check: The Four Gates

The Government of Canada's CDCP eligibility page (2026) sets out four conditions, and you need all four:

1. No access to private dental coverage. That includes coverage through a job, pension, a family member's plan, a professional or student association, insurance you bought, and health spending accounts that pay dental costs.
2. Tax returns filed in Canada for the previous year, by you and by your spouse or common-law partner if you have one.
3. Adjusted family net income under $90,000.
4. Canadian residency for tax purposes, again for both partners where applicable.

The first gate trips people up more than the others. The government counts you as having access to private coverage even if you never enrolled, never used it, didn't pay the premium, or the coverage wouldn't have paid in full. If your employer offered dental and you declined it, you are generally treated as having access.

There is one narrow exception: retirees who opted out of pension dental coverage before December 11, 2023 and can't opt back in. Opting out after that date doesn't qualify you. You also have to confirm every year that you still lack private access, and the government warns that giving false information can lead to removal from the plan and a requirement to repay services.

Gap #1: The Co-Payment Tiers

The CDCP doesn't cover everyone at the same percentage. According to the Government of Canada's CDCP coverage page (updated 2026), your share depends on adjusted family net income:

Look closely at that third row. A family just under the $90,000 line pays more than half of the plan's fee for every covered service. For a household in that bracket, a crown or a set of fillings can still be a real expense, even with full CDCP membership.

Gap #2: Your Dentist's Fee vs. the CDCP Fee

This is the gap most people don't see coming. The co-payment percentages above apply to the CDCP's own fee for a service. Your provider is not obliged to charge exactly that amount. The government page says plainly that CDCP fees may differ from what providers charge, and that you may pay extra when treatment costs more than the plan reimburses.

So your real out-of-pocket on a given visit can be built from up to three layers:

• Your co-payment percentage (if your income is $70,000 or more)
• Any difference between what your dentist charges and what the CDCP pays
• The full cost of anything the plan doesn't cover that you agree to have done

The fix is simple but needs to happen before treatment: ask the office for a written breakdown showing the dentist's fee, the CDCP portion, and your portion, line by line. The government explicitly recommends asking your provider about uncovered costs ahead of time.

Gap #3: Services That Need Preauthorization

Some treatments aren't paid automatically. The coverage page lists services that need approval before the work is done, including:

• Crowns, along with the cores and posts that support them
• Root canal re-treatment
• Partial dentures, and complete immediate dentures and overdentures
• Bonding for loose teeth and post-surgical evaluations
• Conscious sedation, deep sedation and general anesthesia
• Anything beyond the plan's normal frequency limits

The government notes that not every request is approved. If a request is denied, you can still go ahead and pay the provider directly. That's a decision point worth planning for, especially for crowns, which are one of the more expensive items people commonly need.

A sensible preauthorization sequence

1. Get the diagnosis and a written treatment plan.
2. Have the office submit the preauthorization request.
3. While you wait, get a second written estimate for the same work, so you know your fallback cost if it's denied.
4. Only book the procedure once you know which way the decision went, unless your dentist says waiting is clinically risky.

Gap #4: What the CDCP Doesn't Cover

The plan's covered categories are broad: preventive and diagnostic care, basic treatment like fillings and root canals, major items like dentures and extractions, oral surgery, and several forms of anesthesia or sedation. But some things sit outside it.

The most notable is orthodontics. As of the coverage page's 2026 update, the government states that orthodontic services are not currently available under the plan. Anyone hoping the CDCP will help pay for braces or aligners should plan as if they're paying on their own.

Implants and veneers are also not on the published list of covered services. Since the page describes what is covered rather than giving an exhaustive list of exclusions, the safe approach is to assume anything not listed is out-of-pocket and confirm with your provider before you commit.

Putting a Number on Your Gap

Before any significant treatment, build a small table like this with your dentist's office. The numbers are left blank on purpose; the point is to fill them in with real figures from your own estimate.

Add up the last column. That's the number you actually need to budget, and it's the number to compare against any alternative.

Options for the Part the CDCP Won't Pay

Ask about phasing

If your plan includes several items, ask which ones are urgent and which can safely wait. Covered preventive care can often happen right away while you save for the uncovered or high-co-pay items.

Check other government programs

The eligibility page notes you may still qualify for the CDCP if you're also covered by a provincial, territorial or federal program, and that the plans coordinate to avoid paying twice. If you receive provincial social assistance or another public benefit with a dental component, ask how it stacks with the CDCP.

Price uncovered work separately

For items the CDCP won't touch, such as orthodontics, implants or cosmetic work, you're a cash patient like anyone else. That's where comparing prices, including the option of treatment abroad, becomes relevant. Canadians who travel for care should factor in flights, accommodation, time off, and how follow-up visits would work back home. Remember that work done abroad is outside the CDCP, so keep your home records current and ask your Canadian dentist how they'd handle checkups afterward.

Common Misunderstandings

• "I turned down my work plan, so I don't have coverage." For CDCP purposes, being offered coverage generally counts as having access.
• "Under $90,000 means everything's free." Only incomes under $70,000 get the 100% tier, and even then provider fees can exceed CDCP fees.
• "Preauthorization is a formality." The government says some requests are not approved.
• "Braces are covered for kids." The coverage page says orthodontic services aren't currently available.

The Bottom Line

The CDCP is a valuable plan, but it's built around set fees, income tiers and approval rules. Treat it like any coverage: know your tier, ask for a line-by-line estimate, plan for preauthorization outcomes, and budget separately for the services it doesn't include. Do that, and the bill at the end of treatment won't be a surprise.
