Noticing tooth pain after a filling can be worrying. Mild sensitivity or soreness can occur after treatment and often settles within a week or two. However, severe pain, pain that is getting worse or a bite that feels uneven should be checked by a dentist.
Why can a tooth feel sensitive after a filling?
A recently treated tooth may react briefly to cold, heat or sweets. The surrounding gum may also feel tender. Mild symptoms should gradually improve. Sensitivity alone does not automatically mean the filling has failed or that you need a root canal.
If the filled tooth seems to touch before your other teeth, or hurts when you bite, the filling may need an adjustment. Your dentist can check this. Do not try to file the tooth yourself or keep chewing through the pain.
What can you do while the tooth settles?
- Follow your dentist’s aftercare instructions: Wait until numbness wears off before chewing to avoid biting your lip or cheek.
- Choose comfortable foods: Soft foods may be easier to manage. Avoid chewing on the sore tooth and skip very hot or cold drinks if they trigger pain.
- Clean gently: Use a soft-bristled toothbrush. Ask your dentist whether toothpaste for sensitive teeth could help.
- Ask about pain relief: Your dentist or pharmacist can advise what is suitable for you. Follow the product label and your clinician’s instructions.
When should you contact your dentist?
Call promptly if you have persistent pain when biting, intense pain that lingers after hot or cold food, or throbbing pain. Contact the clinic if mild sensitivity is not improving or continues beyond about two weeks. You can call sooner whenever symptoms concern you.
Seek urgent dental care for facial swelling, fever or severe, worsening pain. If swelling makes breathing or swallowing difficult, call 911 or go to an emergency department immediately. Do not wait for an online appointment.
