A tooth that has had an endodontic treatment (root canal) can last as long as natural teeth with proper care. While endodontists do great work and have success rates over 95% there are always cases where the root canal failed to heal properly. The tooth then becomes infected sometimes even years after successful treatment.

Why do I need retreatment?

A Tooth may not heal as expected after a procedure for a number of reasons:

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

For example:

Teeth that decay even further can expose the canal filling material to bacteria which can cause a new infection. A loose, cracked or broken crown can expose the tooth to a new infection. A tooth that has sustained a fracture can also expose the tooth to a new infection. Retreatment involves the following:

  • Prior to the first retreatment appointment the endodontist will examine the tooth and discuss your treatment options.
  • If you and your endodontist have decided on retreatment the endodontist will administer local anesthetic to numb the tooth. After the tooth is numb, the endodontist will have to disassemble the crown and other components to gain access to the root canal filling material.
  • After removing the canal filling, the canals are then cleaned and carefully examined using a microscope.
  • After cleaning the canals, the canals will be filled and sealed and a temporary filling will be placed on the tooth.
  • After the initial retreatment you need to return to you endodontist for the finished crown.
  • If the canals are unusually narrow or blocked, your endodontist may recommend endodontic surgery.
