How to stop a toothache caused by a cavity
Rinse gently, protect the tooth from triggers, use suitable pain relief, and arrange prompt treatment for the cavity causing the toothache.
The short answer
Rinse gently with warm water, keep food out of the cavity, use pain relief only as directed on its label, and arrange prompt dental treatment because a cavity will not heal on its own. Never put aspirin directly on the tooth or gum.
What is the direct answer?
What does this question mean?
A cavity is a chemically damaged area of enamel and dentine caused by acids made when oral bacteria metabolize sugars. As the lesion approaches the pulp, inflammation can produce throbbing pain, temperature sensitivity, or pain on biting.
What can you do next?
A dentist removes infected or softened tissue and restores the tooth with a filling when the pulp remains healthy. If the pulp is inflamed or infected, treatment may involve root canal therapy and a crown, while a non-restorable tooth may require extraction.
When should you seek dental care?
Arrange care promptly for persistent or recurring toothache, pain at night, swelling, a bad taste, or fever. Facial swelling, difficulty swallowing or breathing, or swelling near the eye requires urgent emergency assessment.
What should you ask the dentist?
Ask how deep the lesion is, whether the pulp is alive, and whether an X-ray or cold test is needed. Ask which restoration is appropriate and what symptoms would mean the tooth needs root canal treatment.
Frequently asked questions
Can a cavity toothache go away by itself?
Pain can fluctuate, but the damaged tooth still needs assessment and the underlying lesion can progress.
Should I put clove oil on a cavity?
Clove oil can irritate oral tissue and does not remove decay, so use professional treatment for the cause.
