Ease cavity pain
Cavity pain may be eased briefly by reducing triggers, but the tooth needs treatment to remove decay and protect the pulp.
The short answer
You can reduce cavity pain temporarily by avoiding triggers, keeping the area clean, and using a suitable pain reliever as directed, but only dental treatment removes the decayed tissue and treats the tooth.
What damage inside a tooth causes cavity pain?
A cavity is a local area where acids from bacterial plaque have dissolved mineral from enamel and dentine. When the lesion approaches the pulp, temperature, sweets, pressure, or spontaneous inflammation can stimulate the nerves inside the tooth.
What can you do now to reduce irritation from a cavity?
Rinse away food, brush gently with fluoride toothpaste, and avoid chewing on the painful side. Use medicines only according to their label and your clinician’s advice, and never place aspirin or caustic substances directly on the gum or tooth.
When should cavity pain be checked by a dentist?
Arrange prompt dental care for toothache, lingering sensitivity, a visible hole, food trapping, or pain that interrupts sleep. Urgent assessment is needed for facial swelling, fever, pus, difficulty swallowing or breathing, or rapidly worsening pain.
Can the tooth be restored, and is the pulp inflamed?
Ask how deep the decay is, whether the pulp is inflamed, and whether the tooth can be restored. Ask which material will be used, how the bite will be checked, and what signs after treatment need review.
Frequently asked questions
Can a cavity heal by itself?
Very early mineral loss may be arrested with preventive care, but a formed cavity is a structural defect that needs dental assessment.
Why does the tooth hurt at night?
Inflamed pulp tissue can produce spontaneous or positional pain, especially when decay has progressed toward the nerve.
