Advanced Endodontic Retreatment for Failed Root Canals

Sometimes, even a well-performed root canal may not heal as expected. When symptoms reappear months or years later, endodontic retreatment becomes necessary to give the tooth another chance. At our endodontist office, we specialize in retreatment—a complex and delicate procedure that can often save teeth others might deem hopeless. It’s just one of the ways we extend our commitment to preserving natural smiles and improving dental health outcomes.

There are many reasons a root canal might fail over time. New decay can expose the filling material to bacteria, or a crown may become loose or cracked, allowing reinfection. Sometimes, narrow or curved canals weren’t treated fully the first time due to limited technology or visibility. Whatever the cause, retreatment offers hope. Using modern imaging and magnification, we can see things previous providers may have missed and thoroughly clean the area for a second chance at healing.

Endodontic retreatment starts with the removal of the previous root canal filling material. We then carefully examine the entire canal system, looking for additional or hidden canals, obstructions, or infections that could have been overlooked. With the help of operating microscopes and ultrasonics, we navigate even the most complex root structures to ensure every area is treated completely and accurately. We then disinfect the area and place a new filling, followed by a restoration to protect the tooth.

Patients often wonder whether retreatment is worth it. The answer is yes—especially when it comes to preserving a natural tooth. Extracting a tooth prematurely can lead to further complications, including bone loss, shifting of adjacent teeth, and the need for costly replacement solutions. If the tooth can be saved through retreatment, the benefits in comfort, appearance, and oral function are substantial. Retreatment is also less invasive and less expensive than starting over with an implant or bridge.

One of the advantages of choosing an endodontist for retreatment is our specialized training and access to advanced technology. We see complex cases every day and have the tools to address even the most stubborn issues. Whether it’s navigating calcified canals or removing broken instruments, we are equipped to handle situations that many general dentists are not prepared for. This expertise makes a significant difference in both the success rate and overall patient satisfaction.

The experience of undergoing retreatment is often easier than patients expect. With modern techniques and sedation options, the procedure is typically painless and completed in one or two visits. We also take time to thoroughly explain every step and set realistic expectations. Our goal is to make sure you feel comfortable and informed, from consultation to recovery, while delivering the best possible outcome for your smile.

If you've had a root canal in the past and are now experiencing swelling, discomfort, or sensitivity, it doesn’t necessarily mean the tooth is beyond repair. Endodontic retreatment could provide the solution, extending the life of your tooth for many years to come.
