Learn why you might need endodontic treatment— or retreatment.

To better understand endodontic treatment and the need for retreatment, it is helpful to have a foundational understanding of what endodontic treatment entails.

The word endodontics comes from the Greek; “endo” means “inside” and “odont” is Greek for tooth. Quite literally, endodontics has everything to do with the inside of your tooth. Dental pulp, the inside of the tooth, is comprised of a vast network of nerves, which are interconnected with other parts of the mouth. When you experience tooth pain, it could be due to a variety of conditions, from an abscess to a cracked tooth or a cavity.

The job of your endodontist is to save a diseased tooth and alleviate as much pain as possible. Root canal therapy is used to remove diseased pulp tissue and cover the tooth with a filling or crown to prevent future problems.

Endodontic Treatment

Whether you have had a traumatic accident or are suffering from toothache, an endodontist can diagnose and isolate the problem. One of the most common procedures an endodontist will perform is a root canal treatment. Root canal treatment becomes necessary when the tooth pulp is inflamed or infected. The compromised pulp will need to be removed in order to save your natural tooth. There are five major steps in endodontic treatment protocol your endodontist will typically follow:

  1. Endodontic-TreatmentX-ray and examine the tooth.
  2. Administer a local anaesthetic to numb the tooth. Isolate the tooth with a small protective sheet to keep it clean during the procedure.
  3. Create an opening in the tooth at its crown. Tiny instruments are used to clean the infected pulp from the pulp chamber.
  4. After the space is cleaned up and shaped, fill and seal the root canal with a biocompatible material.
  5. Place a temporary filling over the opening, to be replaced with permanent filling on the next visit.

Endodontic treatment recovery should only take a few days until there is no remaining pain. If pain continues or re-surfaces, this may indicate the need for retreatment.

Endodontic Retreatment

Most of the time, root canal treatment lasts a lifetime. However, it is possible for teeth to heal improperly and become diseased again, months or even years after treatment. The good news is that a retreatment procedure can be used to save your tooth again. You may need retreatment for any number of reasons:

  • Narrow or curved canals inside the tooth were not treated the first time.
  • The placement of a crown was delayed, allowing bacteria to re-enter and gain purchase inside the tooth.
  • Tooth decay re-exposes the root canal to bacteria, causing a new infection.
  • The tooth sustains a fracture or other injury.

Root canal treatment and retreatment are relatively similar in terms of procedural steps. Retreatment takes place because of a complication following the initial procedure. During your retreatment, your endodontist will remove and attempt to restore your canal filling. In either case, endodontic treatment time usually takes between 19 and 55 minutes, with most procedures lasting about 33 minutes.
