Retreatment THERAPY
in Chicago

For a number of reasons, previously treated root canals can sometimes fail to heal or become reinfected. Retreatment (or corrective root canal therapy) is the process of re-performing a root canal. It relieves symptoms and can save your tooth.

When is retreatment therapy necessary?

Retreatment therapy is necessary when root canal treatment does not heal optimally or the tooth becomes reinfected. This can happen for a number of reasons. This includes curved, narrow, or complicated canals that were not treated during the initial treatment; restorations that were not placed within the appropriate amount of time following the initial root canal procedure; or restorations which did not prevent saliva from contaminating the inside of the tooth. In addition, new decay or a fractured or loose restoration can expose the tooth to new infection.

What does the procedure involve?

Retreatments can be complex, requiring high magnification and digital imaging, but this is an area in which the endodontists of Lakeview Endodontics are well-studied and practiced. As with the original root canal treatment, the canals are accessed through the crown (or the outer layer of the tooth). The materials used for the original root canal filling are then removed so the endodontist can carefully examine the inside of the problematic tooth. Any new infection is then addressed, and the endodontist cleans and shapes the canals, placing root canal filling materials and a temporary filling in the crown afterward, as with the original root canal treatment.

As with initial endodontic treatment, a record of your treatment will be sent to your restorative dentist upon completion. Your restorative dentist will decide on what type of restoration is necessary to protect your tooth and restore functionality.
