Dental question about taxonomy:symptom:tooth-pain
Tooth pain usually comes from decay, a crack, exposed dentin, or inflamed pulp and needs assessment when it persists.
The short answer
Tooth pain usually comes from decay, a crack, exposed dentin, or inflamed pulp and needs assessment when it persists. A dentist locates the source with an examination, sensitivity testing, and dental radiographs when indicated.
What can deep or lingering tooth pain indicate?
Pain from the pulp often feels deep, throbbing, or lingering after hot or cold food. Brief sharp pain can arise when exposed dentin in the enamel or root surface lets temperature reach the tooth nerve.
How can you care for the painful tooth today?
Rinse gently, clean around the tooth with a soft brush and floss, and avoid chewing on the painful side. Use a pain medicine only as directed on its label and do not place aspirin or concentrated chemicals on the gum.
When should ongoing tooth pain be examined?
Arrange an examination for pain that lasts, returns, disrupts sleep, or comes with swelling, fever, a bad taste, or pain on biting. Facial swelling, difficulty swallowing, or difficulty breathing needs urgent medical attention.
What should you ask about testing the painful tooth?
Ask whether the pulp, root, gum, or bite is causing the pain and whether an X-ray is needed. Ask which treatment preserves the tooth, what temporary measures are appropriate, and which warning signs require urgent review.
Frequently asked questions
Can tooth pain disappear by itself?
Pain can temporarily settle even while decay, a crack, or pulp damage remains, so recurring pain still warrants an examination.
Why does cold trigger a toothache?
Cold can stimulate exposed dentin or an inflamed pulp through microscopic channels and the tooth's nerve tissue.
