What is removed when Endodontically treating a tooth?
Endodontic treatment removes the damaged pulp. Then the tooth's canals are cleaned and filled to help preserve the tooth. In a few cases, however, nonsurgical endodontic treatment alone cannot save the tooth. In such a case, your dentist or endodontist may recommend surgery.
What causes endodontic treatment failure?
Inappropriate mechanical debridement, persistence of bacteria in the canals and apex, poor obturation quality, over and under extension of the root canal filling, and coronal leakage are some of the commonly attributable causes of failure.
How do you manage failed root canal treatment?
Retreatment has the highest success rate for failed root canals and is the most common treatment solution. Your endodontist will treat the infection, then fill and seal it again to preserve the integrity of the tooth. An extraction and apicoectomy involve: Extraction: When retreatment fails, a tooth may be extracted.
What is non-surgical endodontic treatment?
During a non-surgical root canal procedure, we simply drill farther than we would during a filling so that we can access the root canal (the hollow area inside the tooth with nerves) to clean it. In both cases, anesthetic is used to ensure your comfort and in both cases we fill the hole to prevent further infection.
