How to reduce cavity pain
Cavity pain can be eased temporarily by protecting the tooth and using suitable pain relief, but treatment is needed to address decay.
The short answer
Cavity pain can be eased temporarily by protecting the tooth and using suitable pain relief, but treatment is needed to address decay. A filling may repair a smaller cavity, while deeper decay may require pulp treatment and a protective restoration.
What happens to the tooth when a cavity develops?
A cavity is a damaged area where acids from bacterial plaque have dissolved tooth mineral. Pain can occur when the lesion reaches dentine or irritates the pulp, the living tissue containing nerves and blood vessels inside the tooth.
What can you do now to protect a painful tooth?
Rinse gently with warm water, keep food away from the painful area, and brush carefully with fluoride toothpaste. Use only pain medicine that is appropriate for you and follow its label; do not place aspirin or harsh chemicals on the gum.
When does cavity pain require prompt dental care?
Arrange dental care promptly when pain persists, returns without a trigger, or is worse with heat, cold, biting, or lying down. Facial swelling, fever, a bad taste, or difficulty swallowing needs urgent assessment.
Which treatment is suitable for this cavity?
Ask how deep the decay is, whether the pulp is involved, and which restoration is appropriate. Ask what caused the lesion and how to protect nearby teeth from new decay.
Frequently asked questions
Can a cavity heal on its own once it hurts?
A painful cavity does not repair itself; the tooth needs assessment to determine whether remineralisation, a filling, or deeper treatment is appropriate.
Why does cavity pain get worse at night?
Lying down and reduced distraction can make pain feel stronger, but night pain can also reflect inflammation of the pulp.
