Signs Your Dental Filling Needs to Be Replaced

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.
