Root Canal Retreatment

Root Canal Retreatment Explained

Here is a quick overview video of Root Canal Retreatment

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.

Causes for Retreatment

Retreatment therapy is necessary when root canal therapy or root canal surgery does not heal optimally. The other reason retreatment may be necessary is when the tooth becomes reinfected. These are some of the primary causes:

Complex canals

Sometimes an individual may have a curved or narrow canal or one complicated in its structure. That means that the doctor may not treat it during the initial procedure.

Delayed placement of restorations

If restorations are not placed within an appropriate amount of time following the initial root canal procedure, this can lead to canals becoming reinfected and needing additional treatment.

Improper placement of restorations

When a professional improperly places a restoration, saliva can sometimes contaminate the inside of the tooth. 

Fractured restoration

Sometimes new decay can loosen the restoration and lead to a fracture on the restoration or tooth. A fracture exposes the tooth to a new infection.

Improper treatment

Improper treatment on the root canal system of the tooth during the first root canal can lead retreatment.

Foreign body

Sometimes during the initial root canal procedure a foreign body or object, such as a separated file, is left inside the tooth. This is very rare, but when it happens, retreatment is necessary.

Why should I go to an endodontist?

Retreatments can be complex, requiring high magnification and digital imaging, but this is an area in which our endodontists at Los Angeles Center for Endodontics are well-studied and practiced.   The materials used for the original root canal filling are then removed so our endodontist can carefully examine the inside of the problematic tooth.  Any new infection is then addressed, and our 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.

Once endodontic treatment is complete, we send a record of your treatment to your general dentist. Your general dentist will decide on what type of restoration is necessary to protect your tooth and restore functionality.
