How long do dental fillings last?

Filling lifespan depends on several factors:

Typical lifespans: - Composite (tooth-colored): 7-10+ years - Amalgam (silver): 10-15+ years - Glass ionomer: 5-7 years

Factors affecting longevity: - Size of filling (larger = shorter life) - Location (back teeth wear faster) - Your bite force - Teeth grinding - Oral hygiene - Diet (acidic foods)

Signs a filling needs replacement: - Visible crack in filling - Sensitivity to temperature - Pain when biting - Rough or sharp edge - Dark line around filling - Decay under/around filling

How we monitor fillings: - Check at every exam - Look for wear and cracks - X-rays show decay underneath - Replace before problems occur

Extending filling life: - Good oral hygiene - Regular checkups - Night guard if you grind - Avoid chewing ice/hard objects - Don't use teeth as tools

When fillings fail, options include: - New filling if decay is small - Inlay/onlay for larger areas - Crown if significant structure lost
