Dental Fillings

Signs an Old Dental Filling May Need Replacement

Dental filling used to restore a tooth affected by decay

Old fillings can wear, chip or lose their seal. Replacing a problem filling early may protect the tooth from a larger break or deeper decay.

A filling may need attention even when it is not painful.

Signs to watch for

  • A piece of filling has broken away.
  • The tooth hurts when biting.
  • Cold, hot or sweet food causes new sensitivity.
  • Food repeatedly catches near the filling.
  • Floss tears or gets stuck.
  • The filling feels rough, sharp or loose.
  • A dark line or crack appears around it.

Why old fillings fail

Years of chewing can wear the material and the tooth. Grinding, a large filling, new decay or a crack may also create a gap.

Does every old filling need replacing?

No. Age alone is not a reason to replace a sound filling. The dentist checks the edges, bite, symptoms and X-ray before recommending treatment.

What are the treatment options?

A small damaged area may be repaired. Larger damage may need a new filling, inlay or crown. If decay has reached the nerve, root canal treatment may be discussed.
