IMPROPER HEALING MAY BE CAUSED BY:

• Narrow or curved canals that were not adequately treated during the initial procedure.
• Complex canals that were not detected during the initial procedure.
• The crown or final restoration not being placed within the appropriate amount of time following treatment.
• A defective crown or final restoration that does not prevent saliva from contaminating the inside of the tooth.
• A new cavity that exposed the inside of the tooth, causing a new infection.

Once retreatment has been chosen as the best solution, your endodontist will reopen the tooth to gain access to the canals. He will then clean and disinfect the canals once again and carefully examine the inside of the tooth. After they have been cleaned, the canals will be sealed and a temporary filling will be placed in the tooth.

Once the retreatment is completed, you should return to your dentist as soon as possible to get a new crown or other restoration placed on the tooth to protect and restore it to its full function
