Endodontic Retreatment

Endodontic Retreatment

When given proper care, teeth that undergo endodontic procedures can endure as long as your other natural teeth. However, there are instances where a tooth that has been treated might not fully heal, or discomfort might persist. This discomfort can sometimes emerge months or even years following the initial treatment. In such cases, Endodontic Retreatment could be necessary to address these issues.

Improper healing may be caused by:

  • Curved or narrow canals that were overlooked and not addressed in the initial treatment.
  • Complex canal structures that remained undetected during the first procedure.
  • Delay in the placement of the crown or restoration after the endodontic treatment.
  • A crown or restoration that failed to adequately protect the tooth from saliva contamination, compromising the tooth’s interior.

Factors Leading to Retreatment of a Successfully Treated Tooth:


Even a tooth that was previously treated successfully can encounter new issues that necessitate retreatment:

  • New decay can breach the protective layer over a root canal filling material, leading to infection.
  • A crack or dislodgment in the filling or crown can leave the tooth vulnerable to new infections.

When retreatment has been determined as the necessary course of action, the dental specialists will re-access the interior of your tooth to reach the root canal filling material. This material is then removed to allow for thorough cleaning of the root canals. The specialists will meticulously inspect the interior of the tooth for any issues. After ensuring the canals are clean, they will proceed to fill and seal them, placing a temporary filling in the tooth to protect it until the next step of the treatment.

Following this procedure, it’s crucial to visit your dentist promptly to have a new crown or restoration fitted onto the tooth. This step is essential to restoring the tooth’s full functionality and ensuring its long-term health.
