Dental fillings are a reliable way to restore teeth after cavities—but they don’t last forever. Over time, even the most well-placed fillings can wear down, loosen, or crack. At Orleans Dental Centre, we’re here to help you recognize the signs it’s time to replace your dental filling—so you can avoid discomfort and protect your smile.
Why Fillings Don’t Last Forever
Fillings are constantly exposed to the pressure of chewing, temperature changes, and daily wear. While durable, materials like composite resin or amalgam can eventually:
- Crack or chip
- Shrink away from the tooth
- Stain or discolor
- Trap bacteria and lead to further decay

Common Signs You May Need a Replacement
Watch for these symptoms between dental visits:
1. Tooth Sensitivity
New or increased sensitivity to hot, cold, or sweet foods may signal that your filling is breaking down or no longer sealing the tooth properly.
2. Pain or Discomfort
Sharp pain when biting down could mean the filling has cracked, shifted, or allowed decay underneath.
3. Visible Wear or Cracks
If you notice chips, rough edges, or visible gaps around the filling, it’s time for an evaluation.
4. Discoloration or Dark Spots
Stains around the filling may indicate bacteria or decay beneath the surface.
5. The Filling Feels Loose
If your filling feels unstable or you sense a change in how your bite fits together, it may be deteriorating.

Why Timely Replacement Matters
Delaying filling replacement can lead to:
- More extensive decay
- Tooth fractures
- The need for root canal therapy or even extraction
Early care is easier, less invasive, and more cost-effective.
