If you're asking "how much does it cost to fill a cavity" in 2026, you're not alone. With inflation impacting dental supplies and labor, prices have shifted since 2025. Whether you need a small cavity filling or a big cavity filling on a molar, understanding the breakdown helps you budget and avoid overpaying. Below we cover how much does it cost to get a cavity filled with insurance vs cash, state-specific estimates (Ohio, Texas, California), and what to expect for children's cavities.
The two most common filling materials are amalgam (silver) and composite resin (tooth-colored). Composite is now preferred for front teeth and smaller cavities but costs more. Here’s the national average range for how much does it cost to fill a tooth cavity in 2026:
| Filling Type | Cost per Surface (No Insurance) | With Insurance (after deductible) | Lifespan | Best For |
|---|---|---|---|---|
| Amalgam (Silver) | $120 – $250 | $25 – $70 | 10-15 years | Posterior molars, large cavities |
| Composite Resin | $180 – $450 | $50 – $150 | 5-10 years | Visible teeth, small to medium cavities |
| Glass Ionomer | $150 – $300 | $40 – $100 | 5 years | Children, baby teeth, non-biting surfaces |
| Gold Inlay/Onlay | $600 – $2,500 | $300 – $800 | 15-20+ years | High durability, premium option |
Note: Costs reflect per tooth, single surface. Two-surface or three-surface fillings add $50–$150 per additional surface.
Regional living costs and dentist competition drive price differences. For example, how much does it cost to fill a cavity Ohio is generally lower than coastal metros. Below are typical composite filling ranges (single surface, no insurance) for key states:

| Texas | $170 – $310 | $120 – $200 |
| California | $240 – $480 | $160 – $280 |
| New York | $230 – $460 | $150 – $270 |
| Florida | $180 – $330 | $125 – $210 |

But how much does it cost to fill a big cavity that involves two or three surfaces? Expect to pay $250–$600+ for composite, and sometimes a crown may be recommended instead.
