When Nonsurgical Endodontic Thearpy,

 Root Canal Therapy (RCT), or 

Root Canals are Unsuccessful


I thought all Root Canals Worked!

Fortunately, the vast majority nonsurgical endodontic treatments are successful.  Sometimes though they don't work as planned.  Nonsurgical endoontic therapy is like any other medical procedure, with a small percentage that are unsuccessful. Whether it's called failing, unsuccessful, nonresponder, or it did not respond favorably, something has gone amiss.

Why wasn't the First NSET or Root Canal Treatment Successful?

   Incomplete Cleaning and Sealing.  For root canal therapy to be successful, the canals must be thoroughly cleaned and sealed.  Occasionally, the initial endodontic therapy was unable to remove enough irritants inside your tooth that it fails to heal or pain continues.  More often, the canals are so narrow, hardened, or curved that the tiny instruments used to clean and shape them cannot completely pass through.  Other canals are so small they are extremely difficult to find and went undetected or missed during the first procedure.

  New Decay, Broken Restoration, or Leaking restoration.  These can expose the root canal filling material to bacteria and other irritants in the saliva, causing a new infection in your tooth and an abscess at the end of the root.

  Fracture.  Trauma may have caused the root to fracture.

What Procedures can possibly alleviate the problem?

What are some Treatment Alternatives?

 Retreatment.  This is a nonsurgical approach.  It basically consists of redoing the root canal and is a second chance on maintaining the tooth

Endodontic Surgery.  This is a Surgical approach.   Treatment depends on the cause of failure and still another chance on maintaining the tooth.  The most common surgery is root end resection with root end filing also known as 'apico' or apicoectomy and retrofill

Extraction.  This is where the tooth is removed.  Commonly some type of replacement is needed, otherwise teeth may shift causing a problem with biting
