What is a root canal retreatment? 

 In some cases, endodontically treated teeth may have to be retreated. That is because bacteria sometimes can survive the endodontic treatment, or break the seal of the root canal obturation and re-enter the tooth. That may happen even when the endodontic procedure was performed properly and competently.

Leakage from the oral environment (saliva) through imperfect or broken down restoration or fractured parts of the tooth can considerably add to the problem.

Non-surgical endodontic retreatment procedure is similar to a regular root canal treatment. Previous endodontic obturation will be removed, the system disinfected and sealed again. As a rule, the endodontic retreatment is more complicated, more time consuming, and, consequently, more costly than the initial treatment. In some cases, obstructions of the root canal system such as posts, broken instruments, and carrier materials used previously for the obturation have to be removed. Frequently retreatments are performed in more than one appointment to get the benefit of medicating the tooth in between appointments.

Our state of the art magnification, instruments, and modern techniques assure the high success of endodontic retreatments. A successfully treated tooth should last as long as your other natural teeth.
