Procedure

The retreatment process begins with a thorough examination and imaging, often including 3D scans, to assess the cause of failure. The dentist reopens the tooth to access the root canal filling material, which is removed. The canals are then carefully cleaned, examined for any missed anatomy or infection, and reshaped. If necessary, the endodontist may use advanced tools such as microscopes or ultrasonic instruments to locate and treat hidden canals. Once disinfected, the canals are refilled and sealed. In many cases, a new crown or restoration is placed to protect the tooth.

Procedure Steps

1. Evaluation and X-rays
   1. The endodontist examines the tooth and takes X-rays to assess internal conditions.
2. Accessing the Tooth
   1. The existing crown, filling, and root canal materials (like gutta-percha) are removed.
3. Cleaning & Inspection
   1. The canals are thoroughly cleaned and re-examined, possibly using magnification.
   2. Missed canals, hidden fractures, or unusual anatomy may be addressed.
4. Disinfection & Filling
   1. The canals are disinfected again and sealed with fresh filling material.
5. Restoration
   1. A new filling or crown is placed to protect the tooth.
