title: Why do I need a root canal?
abstract: Bacteria invading the pulp cause pulpal necrosis and the need for endodontic treatment. If bacteria are present after treatment, the root canal may fail. For the root canal to be successful in necrotic cases or retreating failing cases, the bacteria in the root canal walls must be removed and the canal sterilized with calcium hydroxide.
