How long does a filling last?

Dental fillings are a common solution to repair cavities and restore tooth function. However, many people wonder: How long do fillings actually last? The lifespan of a filling depends on several factors, including the type of filling material, oral hygiene habits, and the location of the filling.

Factors Affecting Filling Lifespan

Type of Filling Material:
- Amalgam Fillings: Silver-colored and very durable, lasting typically 10 to 15 years or longer with proper care.
- Composite Resin Fillings: Tooth-colored and aesthetic, usually last around 5 to 7 years but may wear faster in heavy chewing areas.
- Porcelain Fillings: Used for larger restorations, lasting between 10 to 15 years depending on maintenance.
Location of the Filling:
Fillings on molars or teeth exposed to heavy chewing forces may wear out faster.
Oral Hygiene Habits:
Good brushing and flossing extend filling lifespan by preventing new decay.
Diet and Lifestyle:
Consuming sugary foods, grinding teeth, or habits like chewing ice can reduce the durability of fillings.

Signs a Filling May Need Replacement

Sensitivity or pain around the filled tooth.
Visible cracks or chips in the filling.
Rough or uneven filling surface.
Discoloration around the filling.

If you notice any of these signs, visit your dentist for an evaluation.

Final Thoughts

While fillings do not last forever, proper care and regular dental check-ups can significantly extend their lifespan. Knowing your filling type and maintaining good oral hygiene are essential for keeping your teeth healthy.
