How to ease cavity pain
Cavity pain can be eased briefly by avoiding triggers and using suitable pain relief, but the decayed tooth needs dental treatment.
The short answer
To ease cavity pain temporarily, keep the area clean, avoid hot, cold and sugary triggers, and use suitable labelled pain relief, but dental treatment is needed to remove decay and seal or restore the tooth. Pain that lingers after a trigger or starts spontaneously can indicate deeper pulpal inflammation.
What changes inside the tooth cause cavity pain?
A cavity is a localized area where acids from bacterial plaque have dissolved mineral from enamel and dentin. As the lesion approaches the pulp, the living tissue containing nerves and blood vessels can react to temperature, sweets, pressure or bacterial irritation.
What can you do at home to manage cavity discomfort?
Brush gently with fluoride toothpaste and clean around the tooth, then follow the label for a pain medicine that is appropriate for your health history. Do not place aspirin, alcohol or heat on the gum, and do not use a temporary filling product to delay urgent assessment when pain is severe.
When does cavity pain require prompt dental care?
Arrange dental care promptly for cavity pain, especially if it wakes you, persists after cold or spreads to the jaw. Facial swelling, fever, pus, difficulty swallowing or difficulty breathing requires urgent care because infection may be spreading.
Would this cavity need a filling, crown, or root canal?
Ask how deep the cavity is and whether a filling, crown or root canal is needed. Ask what the X-ray shows, how the tooth will be numbed and what symptoms after treatment should lead you to call back.
Frequently asked questions
Can a cavity heal without a filling?
Very early mineral loss may be arrested, but a cavitated hole generally needs professional treatment.
Why does cavity pain come and go?
Pulp irritation can be triggered by temperature, sweets or pressure and may settle before returning as decay progresses.
