What is Endodontic Retreatment?

At Advanced Endodontics Korinthos, we specialize in endodontic retreatment (re-root canal therapy) to save teeth affected by persistent infection or failed root canals. Using a dental microscope and modern techniques, we restore dental health with precision and high success rates.

Endodontic retreatment is the process of correcting a previously treated root canal that did not heal properly or has developed new problems. It allows you to preserve your natural tooth, prevent further infection, and restore function.

When is Retreatment Needed?

Endodontic retreatment is the process of correcting a previously treated root canal that did not heal properly or has developed new problems. It allows you to preserve your natural tooth, prevent further infection, and restore function.

Common reasons include:

‍

• Incomplete cleaning of the root canals.
• Complex root canal anatomy missed initially
• Leakage from a filling or crown
• Cracks in the tooth root or crown
• Persistent pain or inflammation
• Formation of a new abscess

Accurate diagnosis is key, using CBCT imaging, X-rays, and microscopic examination..

Benefits of Endodontic Retreatment

‍

• Preserves your natural tooth.
• Eliminates infection and inflammation.
• Reduces future complications.
• Maintains normal chewing function.
• High success rates with modern techniques.

Retreatment vs. Extraction and Implants

While dental implants are an alternative, retreatment is more conservative, cost-effective, and preserves the natural tooth. Implants require surgery and longer recovery, while retreatment restores your tooth efficiently.
