A root canal is necessary when the pulp layer of a tooth becomes infected. Infection can lead to the loss of a tooth so it is necessary to remove the infection with root canal therapy.
The procedure is generally comfortable and saves the natural tooth, prevents the spread of infection, and returns the smile to complete health.
As occasionally happens with any dental or medical procedure, a tooth may not heal as expected after initial treatment for a variety of reasons. Improper healing may be caused by:
- Curved or narrow canals that were not treated during the initial treatment.
- Complicated root canals that were undetected during initial treatment.
- The crown or restoration was not placed within an appropriate amount of time following the procedure.
- The crown or restoration did not prevent saliva from recontaminating the inside of the tooth.
Or, in some cases, new problems can influence a tooth that was successfully treated:
- New decay can expose a root canal filling material, causing infection.
- A cracked or loose filling or crown can expose the tooth to new infection.
What happens during Retreatment?
Before the procedure begins, Dr. Allan Sandor will discuss your treatment options with you. If you and Dr. Sandor choose retreatment, he 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 canal filling, Dr. Sandor can clean the canals and carefully examine the inside of your tooth using magnification and illumination, searching for any additional canals or unusual anatomy that requires treatment. After cleaning the canals, Dr. Sandor will fill and seal the canals and place a temporary filling in the tooth. If the canals are unusually narrow or blocked, he may recommend endodontic surgery.
After Dr. Sandor completes retreatment, 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 its full function.
