Why is my root canal tooth hurting after years?

Pain in a root‑canal‑treated tooth years later can be caused by a new infection, a missed canal, a cracked root, or an issue with the final restoration (such as a loose crown or new decay). It is not common, but it should be evaluated by a dentist.

- Take a photo of any visible swelling or gum pimple and send it to your clinic for advice.
- Avoid very hot or cold drinks if the tooth feels temperature sensitivity.
- Schedule a review as soon as possible—delaying can make the treatment more complex.
