Why Do I Need Endodontic Retreatment?
The purpose of root canal therapy is to remove infected tissues located inside of your tooth and make sure that no harmful oral bacteria remain. Due to various factors like oddly-shaped teeth or restricted canals, all of the harmful debris may not have been removed. If the inside of the tooth somehow became exposed to new bacteria because the tooth had been damaged, the restoration is cracked, or your tooth enamel has been fractured, endodontic retreatment may be necessary in order to preserve your natural tooth.
