Dental fillings are one of the most common restorative treatments, designed to repair cavities and protect your tooth from further damage. But many patients wonder: how long do fillings actually last? The answer depends on several factors—including the type of filling and how well you care for your smile.
Average Lifespan of Dental Fillings
Most of them last anywhere from 5 to 15 years, but some can last even longer with proper care.
- Composite (tooth-colored) fillings typically last 5–10 years and are popular for their natural appearance.
- Amalgam (silver) fillings are highly durable and can last 10–15 years or more.
- Gold or porcelain fillings may last 15–20 years, though they’re used less frequently today.
No filling lasts forever, which is why regular dental checkups are essential.
What Shortens the Lifespan of a Filling?
Several everyday habits and oral health factors can wear down fillings faster than expected:
- Poor oral hygiene: Inconsistent brushing and flossing allow bacteria to build up, increasing the risk of decay around the filling.
- Teeth grinding or clenching: Excessive pressure can cause them to crack or loosen over time.
- Frequent sugary or acidic foods: These contribute to enamel erosion and can weaken the tooth surrounding the area.
- Large cavities: Fillings placed in larger areas may not last as long due to added stress on the tooth.
- Skipping dental visits: Small issues can go unnoticed and turn into bigger problems without routine exams.
Signs Your Filling May Need Replacement
If you experience sensitivity, pain when biting, rough edges, or notice discoloration around it, it may be time for an evaluation. Addressing these signs early helps prevent further tooth damage.
