Root Canal Retreatment
Even with the best initial treatment, a previously treated tooth may not heal as expected. When that happens, root canal retreatment offers a second opportunity to save your natural tooth and eliminate discomfort. At Purity Endodontics in Los Angeles, our team specializes in identifying the cause of failed root canals and providing advanced, compassionate retreatment options to restore your oral health.

Root canal retreatment is performed when a previously treated tooth fails to heal properly or develops new issues. This can occur months or even years after the original treatment, often due to lingering infection, undetected anatomy, or new decay compromising the seal. Retreatment involves carefully reopening the tooth, removing the old filling materials, thoroughly disinfecting the canals, and resealing the tooth to promote proper healing.
The process is more complex than an initial root canal because the internal structure of the tooth may have changed, and obstructions such as posts or calcifications may be present. At Purity Endodontics, we use advanced tools like cone beam CT imaging and dental microscopes to navigate these challenges with precision and care. Our experience and technology help ensure a safe, effective procedure focused on your long-term oral health.
Choosing retreatment is often a highly effective alternative to extraction. Preserving your natural tooth helps maintain proper bite alignment, jawbone health, and overall dental stability. With proper care following the procedure, many retreated teeth can function comfortably and last for many years.
Frequently Asked Questions (FAQs)
Root Canal Retreatment in Los Angeles, CA
Root canal retreatment has demonstrated excellent success rates, with studies showing that 85-95% of retreated teeth can be saved and function normally for many years. The success of retreatment largely depends on factors such as the initial condition of the tooth, the time elapsed since the original treatment, and the patient’s overall oral health. At Purity Endodontics, our specialized expertise and advanced diagnostic tools allow us to carefully evaluate each case and provide realistic expectations for treatment outcomes. Many patients are surprised to learn that retreatment can be just as successful as the original procedure, making it a valuable option for preserving natural teeth that might otherwise require extraction.
Following root canal retreatment, patients can expect a recovery period similar to that of an initial root canal, typically involving mild discomfort for a few days that can be managed with over-the-counter pain medication. It’s important to avoid chewing on the treated tooth until the permanent restoration is placed, as the temporary filling provides only short-term protection. Most patients can return to normal activities within 24-48 hours, though some sensitivity to temperature or pressure may persist for several weeks as the surrounding tissues heal.
