Sometimes a previously root-treated tooth becomes painful or re-infected. Re-root canal treatment (endodontic retreatment) carefully reopens the tooth, removes the old filling material, disinfects the canals again and reseals them — often saving a tooth that might otherwise be lost.

Re-Root Canal Treatment: common questions
Why did my first root canal fail?
It can happen if a canal was hard to reach, a crown wasn't placed, or new decay let bacteria back in. We identify the cause before retreating.
Is retreatment better than removing the tooth?
Keeping your natural tooth is usually best when possible. We'll advise honestly if retreatment or an alternative is the wiser choice.
