Endodontic Retreatment


While root canals are meant to last for many years, and for some, even a lifetime, there are instances when endodontic retreatment is necessary. Root canal treatment has a success rate of about 92 percent. When there is a failure of healing or new trauma, endodontic retreatment is necessary. This is the process of retreating a tooth that did not heal properly. Improper healing results in a painful, diseased tooth. Dr. Marsheh at Madison Avenue Endodontics has extensive experience in the area of endodontic retreatment and can often help even the most complicated cases.

What happens during endodontic retreatment?

During endodontic retreatment, Dr. Masheh will open the damaged tooth and remove all of the filling materials (gutta percha) that was used in the first procedure. The doctor will then cleanse the canal and remove any infection, clean the canal, and refill it with new filling materials. After healing, Dr. Marsheh will place a new crown.

Causes of Improper Healing

A variety of issues can cause improper healing. If treatment was performed and the crown wasn’t placed in a timely manner, healing could be impeded. Because the pulp of the tooth is accessed through the canal, canals that have an abnormal anatomy might not be able to be completely cleared of pulp. If your restoration did not totally seal the inside of your tooth, saliva may have been able to enter and impact healing.

Causes of New Trauma

New decay or trauma can be caused by fracturing of a tooth, a loosened or broken crown, or decay. Each of these traumas can expose the tooth to bacteria that result in the need for endodontic retreatment.
