When to replace a dental filling?

Fillings are not permanent; they undergo wear and tear every day from chewing and exposure to foods and saliva. Over time, a filling might start to leak (develop tiny gaps between the filling and tooth), crack, or get worn down. It’s important to replace a filling before it fails completely or allows decay to sneak underneath. 

Signs that a filling may need replacement include:

• Tooth Pain or Persistent Sensitivity: If a previously filled tooth starts hurting or has ongoing sensitivity to pressure or temperature, it could mean the filling is no longer sealed well and decay might be present underneath.

• Cracks or Fractures in the Filling: If you or your dentist notice a visible crack in the filling material, it should be redone. Cracked fillings can let in bacteria or even split apart.

• Staining or Dark Edges Around the Filling: Discoloration at the margins of a filling can indicate leakage or decay starting at the edge.

• Rough or Sharp Areas: If you feel a rough spot with your tongue that wasn’t there before, part of the filling may have chipped.

• The Filling Feels Loose or Falls Out: Obviously, if a filling comes out, it needs to be replaced right away to prevent infection and sensitivity.

During your check-ups, we will examine your fillings for any of these issues. If a filling does need replacement, the procedure is similar to the original filling process: we’d remove any remaining old filling and any new decay, then place a new filling. Sometimes, if a cavity has grown or a tooth has fractured around an old filling, a crown might be recommended as a more durable solution. We will explain our findings and recommendations so you can decide on the best course of action.
