Root Canal Retreatment


With proper care, most teeth that have had endodontic (root canal) treatment can last as long as other natural teeth. Root canals have a 95% success rate. 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.

Why do I need retreatment?

As occasionally happens with any dental or medical procedure, a tooth may not heal as expected after initial treatment for a variety of reasons:

Narrow or curved canals were not treated during the initial procedure. Complicated canal anatomy went undetected in the first procedure.

The placement of the crown or other restoration was delayed following the endodontic treatment.

The restoration did not prevent salivary contamination to the inside of the tooth.

In other cases, a new problem can jeopardize a tooth that was successfully treated.

For Example:

New decay can expose the root canal filling material to bacteria, causing a new infection in the tooth. A loose, cracked or broken crown or filling can expose the tooth to a new infection. A tooth sustains a fracture.

Retreatment is performed in two visits and involves the following:

At the initial visit the we will examine the tooth, take x-rays and discuss your  treatment options.   If we decide that retreatment is necessary we will begin the treatment that must be completed to allow the tooth to be saved.  There are instances where the tooth cannot be saved and extraction or periapical surgery may be recommended.    

At the retreatment appointment local anesthetic to numb the tooth is given. After the tooth is numb, 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 canal filling, we will clean the canals and carefully examine the inside of your tooth, searching for any additional canals or unusual anatomy that requires treatment, including fractures.

After cleaning the canals, we will fill and seal the canals and place a post and filling.

After the root canal retreatment and the tooth becomes asymptomatic, you will need to have a crown or other restoration placed on the tooth to protect and restore it to full function.

If the canals are unusually narrow or blocked, or calcified, the prognosis may be guarded and the tooth should be watched for a healing response.  A crown on such a tooth is delayed until the problem is corrected.  If the problem continue the tooth in question may have to be extracted.
