Endodontic Retreatment

With appropriate care and a strong final restoration, teeth that have had endodontic treatment can last for many years. However, healing can be affected by complex root anatomy, delayed restoration, or new damage to the tooth over time. Retreatment may be recommended when symptoms persist, infection returns, or new issues are identified during evaluation. Retreatment may be needed when:

• Curved or narrow canals were difficult to fully treat initially.
• Complex canals went undetected during the first procedure.
• A crown or final restoration was delayed.
• A restoration allowed leakage or contamination inside the tooth.

If retreatment is recommended, the tooth is reopened to access the root canal system. The original filling material is removed so the canals can be thoroughly cleaned and disinfected. Your endodontist will examine the tooth carefully to identify any hidden anatomy, canal variation, or concerns contributing to symptoms. After cleaning, the canals are refilled and sealed, and a temporary restoration is placed. A follow-up appointment with your restorative dentist is important to place a new crown or final restoration. This helps protect the tooth from fracture and prevents bacteria from re-entering the tooth.

In some cases, endodontic surgery may be recommended if retreatment is not the best solution or if symptoms persist. Surgical treatment can help address concerns such as infection near the root tip, fractures, or anatomy that is difficult to treat through the crown of the tooth. The most common surgical procedure is an apicoectomy.

During an apicoectomy, a small incision is made in the gum tissue to access the area near the root tip. Inflamed tissue is removed, the end of the root is treated, and a small filling is placed to help prevent reinfection. Mild swelling or tenderness afterward can be normal, and our team will provide guidance for a comfortable recovery.
