Root canal treatment, also known as endodontic treatment, is a procedure used to treat infected or damaged teeth. During the procedure, the pulp and nerve of the tooth are removed, and the inside of the tooth is cleaned and sealed. In some cases, however, the initial root canal treatment may not be successful, and retreatment may be necessary. In this article, we will discuss when root canal retreatment is necessary and what to expect during the procedure.
When is root canal retreatment necessary?
Root canal retreatment may be necessary if the initial treatment was unsuccessful, or if new problems arise after the treatment. Some of the reasons why retreatment may be necessary include:
Recurrent infection: In some cases, the infection may persist even after the initial root canal treatment. This can happen if some of the infected tissue is left behind or if the sealant used to fill the tooth was not effective.
Cracks or fractures: If the tooth develops a crack or fracture after the initial root canal treatment, bacteria can enter the tooth and cause infection.
Delayed healing: Sometimes, the tooth may not heal properly after the initial root canal treatment, which can cause pain, swelling, and other complications.
New decay: If new decay develops in the tooth after the initial root canal treatment, retreatment may be necessary.
What to expect during root canal retreatment?
The root canal retreatment procedure is similar to the initial root canal treatment, but with a few additional steps. Here is what to expect during the retreatment procedure:
- Local anesthesia: Your dentist will numb the area around the tooth with a local anesthetic to ensure you are comfortable during the procedure.
- Removal of the previous filling material: Your dentist will remove the filling material used in the initial root canal treatment to access the root canal.
- Cleaning the root canal: Your dentist will then clean and disinfect the root canal to remove any remaining bacteria or infected tissue.
- X-rays: Your dentist may take x-rays during the procedure to ensure the root canal is being thoroughly cleaned and disinfected.
- Refilling the root canal: Once the root canal has been thoroughly cleaned and disinfected, your dentist will refill it with a new filling material.
- Temporary filling: Your dentist will place a temporary filling on top of the new filling material to protect the tooth until a permanent restoration can be placed.
- Permanent restoration: After the retreatment procedure is complete, you will need to return to your dentist to have a permanent restoration, such as a crown, placed on the tooth.
Root canal retreatment may be necessary if the initial root canal treatment was unsuccessful or if new problems arise. During the retreatment procedure, your dentist will remove the previous filling material, clean and disinfect the root canal, and refill it with a new filling material. With proper care, the retreated tooth can last a lifetime. If you are experiencing pain or other symptoms after a root canal treatment, contact your dentist to discuss whether retreatment may be necessary.
