Does Dental Insurance Cover Fillings?
Most dental insurance covers fillings as a basic restorative procedure, but the amount covered varies significantly by plan. Deductibles, annual maximums, waiting periods, and material restrictions all affect what you actually pay. Here is a full breakdown of how dental insurance works for fillings.
Updated 28 March 2026
Short answer: Yes, usually
Most dental insurance plans cover fillings as a basic or major restorative procedure. Typical coverage is 50 to 80% of the cost after your annual deductible is met. The main exceptions are: waiting periods (many plans require 6 to 12 months of enrollment before covering major work), annual maximums (most plans cap at $1,000 to $1,500 per year), and material restrictions (some plans only cover amalgam rates for back teeth).
How Dental Insurance Works for Fillings
Most dental insurance uses a tiered coverage structure (often called 100-80-50):
Check-ups, cleanings, X-rays. Usually covered at 100% with no deductible. These are free or very low cost under most plans when you use an in-network dentist.
Fillings, extractions, and basic repair work. Typically covered at 80% after the annual deductible is met. You pay the remaining 20% plus any deductible. Many plans categorise simple composite fillings here.
Crowns, root canals, bridges, and some ceramic fillings. Typically covered at only 50% after the deductible. Complex or laboratory-made restorations often fall here. Large ceramic inlays and onlays may be classified as major rather than basic.
Deductibles and Annual Maximums
Annual deductible
Most dental plans have an annual deductible of $50 to $200 per person. You pay 100% of covered costs until you meet this amount, then coverage kicks in at the plan rate.
Example: $100 deductible, 80% coverage for fillings. A $250 filling costs you $100 (deductible) + $30 (20% of remaining $150) = $130 out of pocket.
Annual maximum
Most dental plans cap their annual benefit at $1,000 to $2,000. Once the plan has paid this amount in a calendar year, you pay 100% of remaining costs.
If you need multiple fillings in one year, you can exhaust the annual maximum quickly. A plan with a $1,000 maximum that covers 80% of basic work pays out its maximum after about $1,250 worth of basic treatment.
Waiting Periods
Many dental insurance plans impose waiting periods before you can claim certain benefits. This prevents people from enrolling only when they already know they need expensive treatment.
| Service type | Typical waiting period | Notes |
|---|---|---|
| Preventive (cleanings, check-ups) | None | Typically available from day 1 |
| Basic restorative (fillings) | 0 to 6 months | Varies by plan; many have no waiting period for fillings |
| Major restorative (crowns, root canals) | 6 to 12 months | Most plans require 6 to 12 months enrollment before covering |
| Orthodontics | 12 months | Where covered at all |
If you enrol in dental insurance specifically because you know you need fillings, check the waiting period for basic restorative work. Some plans have no waiting period for fillings; others require 6 months of enrollment. If you have an immediate need, look for plans with no waiting period, even if they cost slightly more.
Composite vs Amalgam Coverage
Some dental insurance plans pay only at the amalgam rate for back teeth (molars and premolars), even if you get a composite filling. This means the plan pays what amalgam would cost, and you pay the difference between the amalgam rate and the composite fee.
Example of amalgam-rate limitation
Without the amalgam-rate limitation, you would have paid only $50 (20% of $250). The limitation adds $80 to your out-of-pocket cost.
If your plan has this limitation, ask your dentist about it before scheduling. Some patients accept amalgam on back teeth to maximise insurance coverage; others prefer to pay the difference for composite. Your dentist can advise on the clinical options.
No Dental Insurance? Your Options
Dental discount plans
Dental discount plans charge an annual fee ($100 to $200) and provide negotiated discounts of 10 to 60% at participating dentists. Unlike insurance, there are no annual maximums, no waiting periods, and no claim forms. A plan member might pay $100 to $160 for a filling that costs $200 to $280 without coverage. Popular plans include Careington, Aetna Dental Access, and Cigna Dental Savings.
Dental school clinics
Dental schools treat patients at significantly reduced fees ($40 to $120 for a filling) supervised by experienced faculty. Treatment takes longer than at a private practice, but the quality is carefully monitored. Search for dental school clinics by state on the American Dental Association website.
Federally Qualified Health Centers (FQHCs)
FQHCs are government-funded community health centres that provide dental care on a sliding-scale fee based on income. Some provide free or very low-cost fillings to qualifying patients. Find FQHCs in your area at findahealthcenter.hrsa.gov.
Negotiate a cash price
If you are paying out of pocket, ask your dentist for the cash or self-pay price. Dental practices have lower overhead when they do not process insurance claims, and many will offer a modest discount (10 to 20%) for self-pay patients who pay at time of service. It is worth asking.
Common Questions
Does insurance cover fillings on baby teeth?
Most dental plans that include dependent coverage do cover fillings on primary (baby) teeth. Some plans cover children at a higher rate than adults. Check whether your plan includes pediatric dental coverage and at what rate.
Can I get a filling covered if I need it the same day I enrol?
This depends entirely on your plan's waiting period for basic restorative work. Some plans have no waiting period for fillings and will cover them from day one. Others require 6 months of enrollment. Check the specific plan terms before enrolling if you have an immediate need.
What happens if I exceed my annual maximum?
Once your plan has paid its annual maximum, you pay 100% of additional costs for the rest of the calendar year. The maximum resets at the start of the next plan year. If you know you need extensive treatment, consider timing it across two calendar years to use two years of benefits.
