Fillings repair teeth damaged by decay. The price depends mostly on the material and how many surfaces of the tooth are involved.
What’s included
The dentist numbs the tooth, removes decay, and fills it with tooth-colored composite or silver amalgam.
Cost at a glance
| Cost | |

What affects the price
- Material: amalgam (silver) is cheapest; composite (tooth-colored) costs more; gold or porcelain inlays/onlays can run $650-$1,500.
- Size: a one-surface filling costs less than a three-surface filling.
- Back teeth: some plans pay composite fillings on molars only at the amalgam rate.
With dental insurance
Most plans treat this as basic care and pay about 80% after your deductible (usually around $50), up to your annual maximum, so a $200 bill typically leaves you paying around $90. New plans often have waiting periods (6 months for basic, 12 months for major work). Run your own numbers with the dental cost estimator.
Ways to pay less
- Fix cavities early: a small filling is far cheaper than a root canal and crown later.
- Insurance typically pays 70-80% after the deductible.
- Dental discount plans (not insurance) typically cut fees 10-60% at participating dentists, compare with the insurance vs discount plan calculator.
- Dental schools and community health centers offer reduced-fee care. See how to afford dental work.

Frequently asked questions
Does a filling hurt?
You’re numbed, so you should feel pressure but not pain. The tooth may be sensitive for a few days.
Composite or amalgam?
Composite matches your teeth and bonds to them; amalgam is cheaper and very durable. Both are considered safe by the ADA.
