No, fillings are not good for life; they typically last for a specific period.
While dental fillings are a common and effective way to restore teeth damaged by decay, it's important to understand that they are not permanent. Their lifespan depends on several factors:
Factors Affecting Filling Lifespan
- Material Used: Different filling materials have varying durabilities.
- Size of the Filling: Larger fillings tend to be under more stress and may not last as long.
- Location of the Tooth: Fillings in areas with high biting forces may wear down faster.
- Oral Hygiene: Proper oral hygiene significantly impacts the longevity of fillings.
The reference states that fillings are designed to last anywhere from 7 to 20 years, which varies greatly depending on the factors listed above, as well as how well the patient maintains their oral health. Good oral hygiene practices, such as brushing and flossing regularly, can extend the life of a filling.
Signs You Might Need a Filling Replacement
- Sensitivity to hot or cold: This could indicate a crack or leak in the filling.
- Visible cracks or chips in the filling: These weaken the filling and can lead to further decay.
- Pain when biting down: This might mean the filling isn't properly aligned or that decay has developed underneath it.
- Rough edges: You feel sharp or rough edges with your tongue, which can trap bacteria.
Extending the Life of Your Fillings
- Maintain excellent oral hygiene: Brush twice a day and floss daily.
- Visit your dentist regularly: Regular checkups allow your dentist to identify problems early.
- Avoid chewing on hard objects: This can damage or dislodge fillings.
- Consider using a nightguard if you grind your teeth: Grinding can put excessive pressure on fillings.
