Endodontic Retreatment

Although root canal therapy has a very high degree of success, occasionally, a tooth, which has had root canal therapy, may require retreatment, surgery, or even extraction.  Healing is a biologic process and cannot be guaranteed.  Like any tooth, root canal treated teeth can still be subject to decay, gum disease, cracks and fractures, and wearing out of the fillings or crown.  Routine dental checkups and maintenance is recommended.  

Retreatment is very similar to initial root canal treatment.  Like replacing a worn out filling, the old root canal filling is removed, the inside of the tooth is cleaned and disinfected again, and sealed with a new root canal filling.
