With proper care, most teeth that have had endodontic (root canal) treatment can last as long as other natural teeth. In some cases, however, a tooth that has received endodontic treatment fails to heal. 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.
Root Material Placed
In some cases, new problems can influence a tooth that was successfully treated:
- New decay can expose root canal filling material, causing infection.
- A cracked or loose filling or crown can expose the tooth to new infection.
Once retreatment has been selected, your tooth will be reopened and the previously placed filling material removed. After the canals have been cleaned and examined, a new filling will be placed in the roots and the tooth sealed.
At this point, you will need to return to your dentist within a few weeks in order to have a new crown or restoration placed on the tooth.
