When a root canal fails

With proper care, most teeth that have had endodontic therapy (root canal procedure) can last as long as other natural teeth. However, in some cases, a tooth that has received endodontic treatment fails to heal or the tooth pain continues. Occasionally, the tooth becomes painful (tooth nerve pain) or diseased (infected tooth) months or even years after a successful root canal procedure.

If your tooth has failed to heal or has developed new problems, root canal retreatment may be an option. After discussing your treatment options, our plan begins with reopening the tooth to gain access to the old root canal filling material. In most cases, complex restorations such as crowns and bridges can be retained.

Some teeth have multiple canals, split roots and unusual anatomy

After removing the root canal filling, we can clean the canals and carefully examine the inside of your tooth, searching for any additional canals or unusual anatomy that requires additional treatment. After cleaning the canal(s), we will fill and seal the canal(s) and place a temporary filling in the tooth.

After your final visit with us, you will need to return to your dentist as soon as possible to have a new crown or other restoration placed on the tooth to protect and restore it to full function and appearance.
