How to get rid of tooth decay pain
Tooth decay pain is relieved temporarily by protecting the tooth, but lasting relief requires removing decay and restoring or treating the tooth.
The short answer
Tooth decay pain can be eased briefly with appropriate pain relief and by avoiding triggers, but lasting relief requires a dentist to remove decay and restore or treat the tooth.
How do bacterial acids create tooth decay?
Decay is a process in which acids from bacterial plaque dissolve enamel and dentine. Pain can occur when dentine is exposed or when inflammation reaches the pulp, the living tissue containing nerves and blood vessels inside the tooth.
What can reduce discomfort from tooth decay today?
Keep the tooth clean, choose soft foods, and avoid very hot, cold, sweet, or acidic items if they trigger pain. Take an over-the-counter pain medicine only as directed on its label and do not place aspirin against the gum.
When should persistent decay pain be examined?
Book dental care promptly when pain persists, wakes you, or returns after relief fades. Facial swelling, fever, pus, or difficulty swallowing or breathing can indicate spreading infection and requires urgent assessment.
How deep is the decay and what does the X-ray show?
Ask how deep the lesion is, whether the pulp is inflamed, and what an X-ray shows. Ask whether a filling, crown, root canal, or extraction is indicated and what care will protect the remaining tooth structure.
Frequently asked questions
Can tooth decay pain go away on its own?
Pain can temporarily settle even while decay progresses, so disappearing pain does not prove that the tooth has healed.
What should I avoid with a painful decayed tooth?
Avoid chewing on it and limit foods or drinks that provoke sensitivity, especially very hot, cold, sweet, or acidic items.
