Dental pain guide
6 min readPain after a filling
Some sensitivity can happen after a filling, but pain that is worsening, not settling or painful on biting should be checked by the treating dental practice.
A tooth may feel sensitive or different after a filling. This can relate to the depth of the cavity, the bite, the material used, the tooth nerve, or the reason the filling was needed.
The treating dental practice is usually the best first contact because it knows what treatment was done. Worsening or persistent symptoms should not be ignored.

Pain after a filling can have several patterns
Sensitivity to cold, pain on biting, a high-feeling filling or spontaneous ache can suggest different issues. A dentist can check whether the filling, bite or tooth needs further care.
Possible causes or contributing factors
- Short-term tooth sensitivity after dental work.
- A filling that needs bite adjustment.
- A deep cavity, cracked tooth, pulp inflammation or restoration issue.
- Gum soreness from treatment or cleaning around the tooth.
What you can do now
- Contact the treating dental practice if symptoms concern you.
- Avoid chewing hard foods on the tooth if biting hurts.
- Keep the area clean and follow the practice's aftercare instructions.
What not to do
- Do not try to adjust or smooth the filling yourself.
- Do not ignore swelling, fever, a bad taste or worsening pain.
- Do not assume all post-filling pain is expected.
When to contact a dentist
- The filling feels high or the tooth hurts when biting.
- Sensitivity is not settling or becomes spontaneous pain.
- Pain interferes with eating, sleep or normal activities.
When urgent dental care is needed
