3 Signs Your Old Filling Needs a Refresh

If you feel discomfort when eating hot, cold, or sweet foods, your old filling may be leaking or separating from the tooth surface.

When that happens, bacteria can sneak in and cause decay under the filling—something you won’t see, but your dentist will detect during an exam.

Solution: Schedule a quick evaluation. Replacing the filling early prevents deeper decay and saves the tooth from needing more complex treatment later.

Cracks, Chips, or Worn Edges

Over time, fillings naturally wear down or crack under pressure from chewing or teeth grinding.

You may even feel a rough edge with your tongue. These damaged spots can allow bacteria to enter and cause hidden cavities beneath the surface.

Solution: A simple composite filling replacement restores the tooth’s strength and smooth surface—no metal, just a seamless finish that looks and feels natural.

Staining or Dark Lines Around the Filling

If you notice discoloration, dark edges, or staining around an old filling, it may mean that the seal has weakened or new decay has formed nearby.

Older silver (amalgam) fillings are especially prone to this issue, but even composite fillings can lose their bond over time.

Solution: Replacing it with a new composite filling refreshes your smile, strengthens the tooth, and prevents decay from spreading.

Why Choose Composite Fillings

Composite fillings are durable, safe, and blend perfectly with your natural teeth.

Benefits include:

• Tooth-colored finish for a natural look
• Strong bonding that supports the tooth
• Less drilling than traditional fillings
• Long-lasting results with proper care
