Dental insurance in Canada pays a set percentage of each treatment, up to a yearly dollar limit, and most of that limit resets on January 1. Anything you don’t use by December 31 is usually gone for good.
That one fact surprises many people. They pay for a plan through work all year, then leave hundreds of dollars on the table because nobody explained how the plan actually works.
This guide breaks down the terms on your benefits booklet, shows how a claim is calculated and explains how to get the most from your coverage. If you want to talk through your own plan, our team can review your dental insurance payment options in Bolton with you.
The Short Answer: How Canadian Dental Plans Work
Most Canadians with dental coverage get it through an employer group plan. Others buy individual plans or qualify for a government program. Whatever the source, almost every plan runs on the same four rules:
- Coverage percentage: the plan pays a share of each service, such as 80% or 50%.
- Category: services are grouped into preventive, basic and major care, each with its own percentage.
- Annual maximum: the most the plan will pay for you in one benefit year.
- Frequency limits: how often the plan pays for a service, such as one checkup every six or nine months.
The Ontario Dental Association notes that there are more than 30,000 different dental benefit plans in Ontario, so it’s important to understand your own. The terms below will help you read your booklet with confidence.
Key Dental Insurance Terms Explained
Term | What it means | Example |
|---|---|---|
Premium | What you or your employer pays to keep the plan active | Deducted from each paycheque |
Co-insurance | The percentage the plan pays for a service | 80% for basic care, you pay 20% |
Deductible | An amount you pay before the plan starts paying | $25 per person per year |
Annual maximum | The most the plan pays for you per benefit year | $1,500 per person |
Frequency limit | How often a service is covered | One recall exam every 9 months |
Fee guide | The fee schedule the plan uses to calculate payment | A specific year of the ODA Suggested Fee Guide |
Predetermination | An estimate sent to your insurer before treatment | Submitted before a crown is booked |
Coordination of benefits | How two plans share one bill | Your plan pays first, your spouse’s plan pays the rest |
What Is Usually Covered (and at What Percentage)
Plans differ, but most group plans in Canada follow a three-tier pattern. Your booklet may use slightly different names.
Category | Common services | Typical coverage |
|---|---|---|
Preventive | Exams, cleanings, X-rays, fluoride, sealants | 80–100% |
Basic | Fillings, simple extractions, root canals, gum treatment | 70–80% |
Major | Crowns, bridges, dentures, implants | About 50%, often with a lower annual limit |
Orthodontic | Braces, clear aligners | Often 50%, with a separate lifetime maximum and age limit |
Two details matter here. First, some plans put root canals and gum treatment under major care rather than basic care. Second, orthodontic coverage is frequently missing altogether or limited to dependents under a certain age.
What Is Usually Not Covered
- Cosmetic treatments such as teeth whitening
- Services above your frequency limits
- The difference between your dentist’s fee and your plan’s fee guide
- Treatment started before your coverage began
- Implants, on many basic plans
How a Dental Claim Is Calculated
The percentage on your booklet applies to the plan’s approved fee, not always to the amount on your bill. Here is a simple example for a filling under a plan that pays 80% of basic services.
Step | Amount |
|---|---|
Dentist’s fee for the filling | $200 |
Plan’s approved fee (based on its fee guide year) | $190 |
Plan pays 80% of $190 | $152 |
You pay ($200 minus $152) | $48 |
The gap of $10 comes from the fee guide year. Some employers keep their plan on an older fee guide to control costs, so the plan’s approved fee trails current fees. Your dentist can’t change that. It’s set by the plan.
Annual Maximums and the December 31 Reset
Most plans run on the calendar year. Your annual maximum and any deductible reset on January 1, and unused dollars don’t carry over.
That creates a real planning opportunity in the fall. If you have treatment that’s been recommended but not done, booking it before the year ends can let you use this year’s maximum instead of eating into next year’s.
Splitting Treatment Across Two Benefit Years
Larger treatment plans can sometimes be split. For example, a patient who needs two crowns might complete one in December and one in January. Each crown then draws from a different year’s maximum.
Splitting only works when it’s clinically safe to wait. Your dentist will tell you which treatment can wait and which can’t.

Frequency Limits: Why "Every Six Months" Isn't Always Covered
Many people assume two cleanings a year are covered. Some plans in Ontario now cover a recall exam once every nine months, and some limit scaling to a set number of units (time blocks) per year.
Check these limits before you book:
- How often a recall exam is covered (6, 9 or 12 months)
- How many units of scaling are covered per year
- How often bitewing X-rays and full-mouth X-rays are covered
- Whether fluoride is covered for adults or only for children
Our hygiene team can help you plan visits around those limits. A regular dental cleaning in Bolton is easier to keep up when you know exactly what your plan pays for.
Predeterminations: Know the Cost Before Treatment
A predetermination (also called a pre-treatment estimate) is a form your dental office sends to your insurer before major work. The insurer replies with what it will pay.
Ask for one when:
- The treatment is a crown, bridge, denture, implant or orthodontics.
- The total cost is high enough to affect your budget.
- You’re unsure whether your plan covers the service at all.
A reply usually takes a few days to a few weeks. It shows the plan’s portion and your portion, so there are no surprises on the day of treatment. For example, if your dentist recommends dental crown treatment in Bolton, a predetermination tells you your share before you commit.
Two Plans? How Coordination of Benefits Works
If you’re covered by your own plan and your spouse’s plan, both can contribute to the same bill. The order is set by industry rules:
Who is the patient | Plan that pays first | Plan that pays second |
|---|---|---|
You | Your own plan | Your spouse’s plan |
Your spouse | Their own plan | Your plan |
Your child | The plan of the parent whose birthday (month and day) comes first in the calendar year | The other parent’s plan |
With two plans, your out-of-pocket cost for routine care can drop close to zero. You’ll need both plans’ details on file, so bring both cards to your visit.
Government Dental Programs in Ontario
Some people don’t have private coverage. Several public programs may help, depending on age and income:
- Canadian Dental Care Plan (CDCP): federal coverage for eligible residents with an adjusted family net income under $90,000 and no access to private dental insurance
- Healthy Smiles Ontario: free dental care for eligible children and youth 17 and under
- Ontario Seniors Dental Care Program: for eligible low-income seniors 65 and over
- ODSP and Ontario Works: dental coverage for eligible recipients
One rule catches people out. If you have access to private dental insurance through work, you’re not eligible for CDCP, even if you choose not to use your work plan.

7 Ways to Get the Most From Your Dental Benefits
- Read your booklet once a year. Note your annual maximum, percentages and frequency limits.
- Book recall visits early in the year. Popular December slots fill fast.
- Finish recommended treatment before December 31. Unused dollars don’t roll over.
- Ask for a predetermination on major work. Know your share in writing.
- Add a spouse’s plan to your file. Coordination of benefits can cover the gap.
- Treat problems while they’re small. A small filling costs far less than a crown or root canal later.
- Ask about payment plans for your share. Spreading the cost can make needed care easier to start.
Signs You're Not Using Your Plan Well
- You haven’t had a checkup in over a year, but you have coverage
- You’ve been told you need treatment and have put it off for months
- You don’t know your annual maximum
- You’ve only ever submitted claims under one of two available plans
- You discover each January that last year’s benefits went unused
If any of these sound familiar, a quick call can sort it out. As a new patient dentist in Bolton, we can check your coverage when you book your first exam.

Frequently Asked Questions
1. How does dental insurance work in Canada?
A dental plan pays a percentage of each covered service, up to an annual maximum. Most plans group services into preventive, basic and major categories, each paid at a different rate.
2. Do dental benefits reset every year?
Yes, for most plans. Annual maximums usually reset on January 1, and unused amounts don't carry over to the next year.
3. What is a typical annual maximum for dental insurance in Canada?
Many group plans set an annual maximum between $1,000 and $2,500 per person. Your benefits booklet lists your exact amount.
4. Why didn't my insurance pay the full 80%?
Plans pay a percentage of their own approved fee, which may be based on an older fee guide. You pay the difference between that fee and the dentist's fee.
5. What is a dental predetermination?
It's a cost estimate your dental office sends to your insurer before treatment. The insurer replies with how much it will pay, so you know your share in advance.
6. Can I use two dental insurance plans?
Yes. Coordination of benefits lets a second plan pay some or all of what the first plan didn't, up to each plan's limits.
7. Does dental insurance cover teeth whitening?
Usually not. Whitening and most other cosmetic treatments are generally excluded from Canadian dental plans.
8. Can I get CDCP if I have work dental benefits?
No. Having access to private dental insurance makes you ineligible for the Canadian Dental Care Plan, even if you don't use it.
