Do Old Fillings Need to Be Replaced? Signs Your Dental Work May Be Failing
Quick Answer
Fillings do not last forever. Over time they can wear, crack, or develop gaps that allow bacteria to enter. If symptoms like sensitivity or pain appear, evaluation is recommended.
Why Fillings Wear Out
Fillings face constant:
- chewing pressure
- temperature changes
- mechanical stress
Over time, they may loosen or develop gaps.
Signs a Filling May Be Failing
- sensitivity to cold or sweets
- pain when biting
- food getting stuck
- rough edges
- visible discoloration
- bite feels uneven
Why Replacement Matters
If a filling fails:
- bacteria can enter underneath
- decay can develop unseen
- damage can worsen
Early replacement may prevent larger treatments later.
How Silver State Smiles Evaluates Fillings
- checking margins and edges
- evaluating surrounding enamel
- analyzing bite pressure
- using X-rays to detect hidden decay
When Replacement Is Not Needed
If a filling is stable and sealed, it may just be monitored.
Dentistry is based on condition, not age.
If an old filling feels different or has become sensitive, Silver State Smiles can determine whether simple replacement or further treatment is needed.
