In some cases, however, a tooth that has received endodontic treatment fails to heal or the pain continues. Occasionally, the tooth becomes painful or diseased months or even years after successful treatment. If your tooth has failed to heal or has developed new problems, you have a second chance. Another endodontic procedure may be able to save your tooth.
As occasionally happens with any dental or medical procedure, a tooth may not heal as expected after initial treatment for a variety of reasons:
- Cavities or gum disease can develop on a root canal treated tooth.
- The patient failed to maintain good oral hygiene.
- The tooth/sealing materials have degraded or broken down over time.
