A Re-Root Canal Treatment (Re-RCT) is a procedure performed when a tooth that has previously undergone root canal treatment fails to heal properly or becomes infected again. Instead of extracting the tooth, Re-RCT can often save the natural tooth and restore its function.
Why Is Re-RCT Needed?
A previously treated tooth may require retreatment due to:
- Persistent pain or sensitivity
- Infection that was not completely removed
- Missed or complex root canals
- New decay around the treated tooth
- Cracked or damaged crowns/fillings
- Recontamination caused by leakage
- Swelling, abscess, or gum infection
How Is Re-RCT Performed?
- Removal of old root canal filling material
- Removal of the existing crown or filling
- Thorough cleaning and disinfection of the canals
- Identification and treatment of missed canals
- Refilling and sealing the canals
- Placement of a new restoration or crown
Don’t rush to extract a failed root canal tooth. Re-RCT may provide a second chance to save your natural smile.
