Endodontic retreatment is similar to root canal therapy, but is only necessary if a previous root canal has failed or becomes infected again. The treatment plan for endodontic retreatment includes removing your previous filling, reshaping, and sterilizing the affected area, then refilling the root canal with a new material.
Endodontic retreatments can take longer than your first root canal procedure to complete. This is because many patients have undergone restorative procedures after a previous root canal to protect their tooth and since we need to reopen the infected tooth canal, we may need to remove crowns and any other materials to gain access.
If your tooth’s root canal is too narrow or is blocked, we may recommend endodontic surgery to fix the issue. If the canal is healthy and can be refilled during your endodontic retreatment, we will fill, reseal, and place a temporary filling in the tooth to better protect the affected area. After your endodontic retreatment is complete, it is recommended that you visit your dentist as soon as possible to have a new crown placed to better protect the tooth.
