Managing Failed Root Canals: Enhancing Success Rates with Re-RCT

Re-RCT, or retreatment of a root canal, is a dental procedure performed when a previously treated tooth requires additional treatment due to persistent infection or complications. It involves the removal of existing root canal filling materials, cleaning, disinfection, and resealing of the tooth’s root canal system to promote healing and preserve the tooth.

How Does it work

Re-RCT begins with the evaluation of the tooth’s condition through clinical examination and imaging. The previous root canal filling is carefully removed, and the canal space is thoroughly cleaned and disinfected. Any missed canals or complicated anatomy is addressed. The canals are then sealed with new filling material, and a temporary or permanent restoration is placed to protect the tooth. 


  • Removal of previous root canal filling
  • Thorough cleaning and disinfection of the root canal system
  • Identification and management of missed canals or complex anatomy
  • Sealing of the canals with new filling material
  • Placement of a temporary or permanent restoration to protect the tooth.

Treatment steps

  1. Evaluation of the tooth’s condition and review of previous root canal treatment.
  2. Removal of the existing root canal filling material.
  3. Cleaning and disinfection of the root canal system.
  4. Identification and management of any missed canals or complex anatomy.
  5. Sealing of the canals with new filling material and placement of a temporary or permanent restoration.

Session: A session of Re-RCT typically refers to a dental appointment during which the retreatment procedure is performed on the affected tooth.

Duration:  1 to 2 hours 

Painful or Painless: Re-RCT is performed under local anesthesia, ensuring that the procedure itself is generally painless. Some discomfort and sensitivity may be experienced during the recovery period, but it can be managed with over-the-counter pain medication. The goal of Re-RCT is to alleviate pain and resolve any existing dental issues.

Benefits of Re-RCT

  • Preservation of the natural tooth and avoidance of extraction
  • Elimination of persistent infection or inflammation
  • Restoration of oral health and function
  • The improved long-term success of the root canal treatment
  • Enhanced aesthetics and preservation of the natural smile.


Re-RCT offers a valuable solution for cases where a previously treated tooth requires additional treatment. By addressing unresolved issues and providing thorough disinfection and sealing of the root canal system, Re-RCT aims to save the natural tooth, promote healing, and restore oral health. With its benefits of preserving the tooth’s structure and functionality, Re-RCT can be an effective option to consider before considering extraction.

During the course of having laser hair removal sessions, we will only allow you to shave or trim your hair. This is because waxing and plucking will pull the hair out of the root meaning the laser will be less effective at your next session.
