Endodontic Retreatment

​

With the appropriate care, your teeth that have had endodontic treatment will last as long as other natural teeth. Yet, a tooth that has received treatment may fail to heal or pain may continue to exist. Sometimes, the pain may occur months or years after treatment
Improper healing may be caused by:

• Curved or narrow canals that were not treated during the initial

treatment.
• Complicated canals that went undetected during the

initial treatment.
• The crown or restoration was not placed within the appropriate

amount of timefollowing the procedure.
• The crown or restoration that did not prevent saliva from

contaminating the inside of the tooth.
• New decay can expose a root canal filling material, causing infection.
• A cracked or loose filling or crown can expose the tooth to new infection.
