Endodontic Retreatment

Why do I need a retreatment of my root canal?
After root canal treatment, most teeth function as well as natural teeth. However, some circumstances may cause an endodontically treated tooth to have recurrent disease resulting in swelling, pain, or infection, even after several years have passed since the initial treatment. A tooth may not heal as expected when there is complicated tooth anatomy, delayed placement of a crown or filling after the original root canal, saliva leakage under a broken filling, deep decay, or trauma.

After evaluating the dental history, tooth, and digital x-rays, your endodontist will discuss the case with you and determine whether a retreatment, or revisional treatment, is indicated.

How is a retreatment performed?
During retreatment, your endodontist will examine the inside of the tooth for causes that may have prevented proper healing following initial treatment. We will use the microscope to check for evidence of cracks, complex or unusual canal shapes, decay, and blockages. The filling material will be removed from the canals and the canal system will be cleaned, then filled and sealed. After the retreatment has been completed, you will need to visit your general dentist as soon as possible to have a new permanent restoration placed to return your tooth to its full function.
