Root Canal Retreatment: What Happens When a Root Canal Fails?

A root canal that doesn't heal as expected isn't the end of the road for your tooth. Root canal retreatment is a second attempt to clean, disinfect, and seal a tooth that didn't heal properly after its first root canal — the original treatment may have left infection behind, or the tooth may have become exposed to new bacteria later. At Lakeside Dental in Moses Lake, Dr. Brad Earl, who received advanced training in endodontics, helps patients understand whether retreatment can save the natural tooth.
