Though it isn’t common, some patients’ teeth get re-infected after root canal therapy. This can happen if all the infection isn’t cleared out, often due to a complicated tooth root structure or if there’s a structural issue with the protections we put in place.
If you’re one of these patients, one of our dentists will thoroughly clean out your tooth and refill it. Reinfection doesn’t mean your tooth is lost, as another root canal can still preserve your tooth.
