Dental fillings don’t last forever. Even the best-placed filling eventually wears down, cracks, or pulls away from the tooth, creating a gap where bacteria can enter. Knowing the warning signs of a failing filling can save you from more extensive dental work down the road.
How Long Should a Filling Last?
Lifespan varies by material:
- Amalgam (silver) fillings: 10 to 15 years on average
- Composite (tooth-colored) fillings: 5 to 10 years
- Gold fillings: 15 to 20 years or longer
- Ceramic fillings: 10 to 15 years
These are averages. Individual factors like teeth grinding, diet, oral hygiene, and the size of the original filling all play a role.
Signs Your Filling May Need Replacement
- Tooth sensitivity to hot, cold, or sweet foods
- Pain when biting or chewing
- A visible crack or chip in the filling material
- Floss shredding when passing between the filled tooth and its neighbor
- Dark lines around the edge of the filling (may indicate leakage)
- A rough or uneven surface that traps food
If you notice any of these signs, schedule an exam. What starts as a simple replacement can become a root canal if decay reaches the tooth’s pulp.
What Happens During a Filling Replacement
The dentist removes the old filling material along with any decay that has developed underneath. The tooth is cleaned, shaped, and the new filling is placed. In most cases, the procedure is completed in a single visit.
Should You Upgrade to Composite?
Many Elk Grove patients choose to replace aging amalgam fillings with tooth-colored composite. The benefits include better aesthetics, no mercury content, and a tighter seal against the tooth structure. Composite fillings bond directly to the tooth, helping to strengthen it.
Preventive Tips
- Brush twice a day with fluoride toothpaste and floss daily.
- Avoid chewing hard objects like ice or pens.
- If you grind your teeth, ask about a nightguard.
- Keep regular six-month checkup appointments.
Old fillings don’t give much warning before they fail. A simple replacement now beats a root canal later.
