With the appropriate care, your teeth that have had endodontic treatment will last as long as other natural teeth. However, a tooth that has received treatment may fail to heal or pain may continue to exist. Sometimes, problems may occur months or years after treatment. If so, Endodontic Retreatment may be needed.
Improper healing may be caused by:
Curved or narrow canals were not treated during the initial treatment.
Complicated canals went undetected during the initial treatment.
The crown or restoration was not placed within the appropriate amount of time following the procedure.
The crown or restoration did not prevent saliva from contaminating the inside of the tooth.
