Cavity pain killer
Pain from a cavity may ease with a pain reliever, but the decay needs dental treatment to remove the infected tooth structure.
The short answer
A pain reliever can temporarily reduce cavity pain, but it cannot remove decay or repair the tooth.
What is the direct answer?
What does this question mean?
A cavity is a hole created when bacterial acids dissolve enamel and dentine. Pain can arise when inflammation reaches the pulp, the living tissue containing nerves and blood vessels.
What can you do next?
Follow the medicine label and avoid placing tablets directly on the gum. Arrange an examination so the dentist can check the cavity, test the pulp, remove softened tissue, and restore the tooth with a filling or other treatment.
When should you seek dental care?
Seek urgent care for facial swelling, fever, difficulty swallowing or breathing, or pain that is severe, persistent, or stopping sleep. A dentist should also assess sensitivity that lingers after hot or cold drinks.
What should you ask the dentist?
Ask whether the decay has reached dentine or the pulp, whether a filling is suitable, and what pain-relief options fit your medicines and medical conditions.
Frequently asked questions
Can a cavity heal by itself?
A formed hole does not grow back. Early enamel changes may sometimes be managed with fluoride, but an examination is needed to tell the difference.
Why does cold hurt a cavity?
Fluid movement through exposed or weakened dentine can stimulate the pulp and create a sharp response.
