What is the lifespan of a dental filling?

Dental fillings are quite durable, but their longevity depends on several factors including the material used, the size of the filling, your oral habits, and how well you care for your teeth. On average, composite (white) fillings last about 5 to 10 years. Amalgam (silver) fillings can last 10 to 15 years or more. High-quality gold or porcelain inlays/onlays might last 15-20 years. Remember, these are averages – some fillings last longer, and some may need replacement sooner if conditions change.

To maximize the lifespan of your fillings and prevent new cavities from forming, follow these aftercare tips:

Maintain Excellent Oral Hygiene

Continue to brush at least twice a day with fluoride toothpaste and floss daily. Good hygiene prevents plaque buildup around the edges of fillings, which is where decay can sometimes start again.

Watch Your Diet

Limit frequent snacking on sugary or sticky foods and drinks. A healthy diet that’s low in sugar helps prevent decay on all your teeth, including those with fillings. Also, minimize very hard foods (like biting on ice or hard candy) that could crack a filling or tooth.

Mouthguard for Grinding

If you clench or grind your teeth at night (bruxism), consider getting a custom nightguard. Grinding can wear down teeth and fillings prematurely. A nightguard will protect your dental work and your natural teeth from excessive force.

Regular Dental Check-ups

Don’t skip your routine check-ups and cleanings. During these visits, we inspect your fillings to ensure they remain intact and sealed. We can catch any wear or leakage early and fix or replace a filling before it causes a bigger problem. Professional cleanings also keep your whole mouth healthier, which benefits your fillings too.

Avoid Using Teeth as Tools

Don’t use your teeth to open packages, bottles, or bite non-food objects (pens, fingernails, etc.). Such habits can chip or stress fillings (and teeth in general).
