Understanding Persistent Tooth Pain Months After a Filling

Experiencing tooth pain months after receiving a filling can be concerning. While some sensitivity is normal shortly after the procedure, persistent discomfort may indicate underlying issues that require attention.

Common Causes of Tooth Pain Months After a Filling

  1. Infection: If bacteria infiltrate the filled tooth, an infection can develop, leading to throbbing pain and sensitivity. This may occur if the filling was not properly sealed or if decay was not entirely removed before placement.
  2. Wear and Tear: Over time, fillings can deteriorate, creating gaps between the filling and the tooth. These spaces allow bacteria to enter, causing further decay and discomfort.
  3. Cracks or Fractures: Habits like teeth grinding (bruxism) can cause fillings to crack, exposing sensitive areas of the tooth and leading to pain.
  4. Leaking Filling: Improper sealing of a filling can result in leakage, where saliva and bacteria seep into the tooth, causing decay or infection. This often leads to pain when biting or chewing.
  5. Allergic Reaction: Some individuals may be allergic to materials used in fillings, such as metals in amalgam fillings or resins in composite fillings. Symptoms include pain, swelling, and redness around the affected tooth.
