Root Canals
The endodontist examines and x-rays the tooth, then administers local anesthetic. After the tooth is numb a small protective sheet called a "rubber dam" is placed isolating the tooth and keeping it clean and dry.
An opening is made in the tooth and very small instruments are used to clean the pulp from the pulp chamber and root canals and to shape the space for filling.
After the space is cleaned and shaped, the endodontist fills the root canals with a biocompatible material, usually a rubber-like material called "gutta-purcha". The gutta-percha is placed with an adhesive cement to ensure complete sealing of the root canals. In most cases, a temporary filling is placed to close the opening.
Following the final visit with your endodontist, you must return to your dentist to have a crown or other restoration placed to protect and restore the tooth to full function. The bone heals and the infection is eliminated.
Retreatment
The endodontist will discuss your treatment options. If retreatment is chosen the doctor will remove the restorative materials gaining access to the root canals.
After removing the canal filling, the endodontist will clean the canals and carefully examine the inside of your tooth, searching for any additional canals, fractures or unusual anatomy that requires treatment. The endodontic microscope is an invaluable tool utilized by the endodontists during this procedure.
The clean canals are filled and a temporary filling is placed. After the final visit with the endodontist, 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 full function.
