Can a Third Root Canal Prevent Extraction and Save My Tooth?

Posted by AllSmiles

I have a tooth with a root canal that was redone in 2015. It is bothering me again. Can I get a third root canal, or will I lose the tooth? – Thanks. Erika from FL

Erika,

Root canal treatment, while a standard procedure, has limitations. Despite careful execution, a recognized failure rate of 5-15% can increase with less experienced dentists.

The complexity of the tooth’s anatomy plays a significant role. The pulp chamber and its canals can have intricate branching patterns, particularly in molars. While dental files navigate these canals, certain anatomical variations, such as sharp bends or small, hidden canals, can make complete cleaning and sealing challenging.

Retreatment can be attempted when a root canal fails, but its success rate is lower, often around 50-75%. If retreatment fails, a dentist may recommend surgical intervention, known as an apicoectomy and retrofill. This procedure involves accessing the root tip through a small incision in the gum tissue and removing the infected portion. However, it’s not always feasible, especially in cases where the root’s position or proximity to vital structures makes surgery risky.

Ultimately, tooth extraction and a dental implant may become necessary if all conservative treatments fail.
