Expert Retreatment Procedures

In some cases, it may be necessary to “retreat” or “revise” a root canal due to an infection following initial treatment. It is common for a root canal retreatment or complication to occur. This can be the result of insufficient root canal therapy, complicated canal anatomy, or a leaking restoration that becomes contaminated with oral bacteria.

Root Canal Retreatment: What Is It?

In most cases, teeth that have undergone root canal treatment will last a lifetime. There are, however, occasions when a root canal-treated tooth does not heal properly. Root canal retreatment (or endodontic retreatment) is a non-surgical procedure that addresses a failed root canal. Our endodontists identify previously undetected problems and meticulously resolve them by removing root canal fillings, cleaning them, shaping them, and then sealing them.

After teeth have been successfully retreated, chewing, biting, and other basic functions can be resumed without symptoms of pain or discomfort.

One common problem associated with frenums is gum recession. When a frenum pulls tightly on the gums, it can cause localized areas of recession, leaving the tooth roots exposed and vulnerable. Additionally, a tight frenum can create gaps between teeth, known as diastema, as it pulls the teeth apart.

Reasons for Retreating a Root Canal

In the case of a failed root canal, an endodontic retreatment may be necessary. It is a relatively rare occurrence. Studies indicate that root canals have a success rate of 98%. It is possible, however, for a root canal to fail from time to time. A root canal may fail due to the following problems:

  • Persistent bacterial infection
  • Underfilled canals
  • Overfilled canals
  • Canals that were missed or hidden
  • A leak caused by an improper seal

What Are the Symptoms of a Failed Root Canal?

The symptoms of root canal failure can be difficult to identify because they vary from case to case. It is possible that you will experience sensitivity to pressure. In some cases, patients describe general discomfort or an “achy” sensation in the area. There may be throbbing or swelling in the face in severe cases. It is also possible that you will not feel any discomfort at all. In this case, regular dental care will be essential to catch the problem early before it worsens.

The process of retreating a root canal

Once our endodontists have carefully examined your mouth and discussed your options, the previous root canal filling material will be removed. After accessing the roots, we carefully re-clean the canals to remove any new decay or bacteria. Your affected tooth and adjacent teeth will be evaluated using a surgical microscope and digital radiography. In order to seal the root canal system, our endodontists will clean and shape the canals.

In a few weeks, your general dentist will either fit your tooth with a new restoration (a crown or filling) or repair your existing restoration.

The treatment of a failed root canal requires expertise and care. When it comes to endodontic treatment, your comfort and well-being are of the utmost importance to us. We will do everything we can to relieve your pain and restore your healthy smile as soon as possible.
