Endodontic Retreatment

Teeth that have had root canal treatment can last a lifetime with proper care. But sometimes, a tooth that has been treated doesn’t heal properly or develops new problems months or even years after treatment. In these cases, an additional procedure may be able to support healing and save your tooth. If you have pain or discomfort in a previously treated tooth, talk to us about retreatment.

What to expect if you need root canal retreatment

First, we will discuss your options. If you choose retreatment, we will reopen your tooth to gain access to the root canal filling material. In many cases, complex restorative materials (crown, post and core material) must be disassembled and removed to permit access to the root canals.

After removing the gutta percha canal filling, we clean the canals and carefully examine the inside of your tooth using magnification and illumination, looking for any additional canals or unusual anatomy that requires treatment. We will then disinfect, fill and seal them and place a temporary filling in the tooth. If the canals are unusually narrow or blocked, we may recommend endodontic surgery. This surgery involves making an incision to allow the other end of the root to be sealed.

After your retreatment is complete, you will be referred back to your usual dentist to have a new crown or other restoration placed on the tooth to protect and restore it to its full function.
