Extracted premolar tooth and root. Sectioned views of an extracted premolar tooth and the fractured root. The views show the ways in which the tooth's root canals were filled after endodontic treatment (root canal surgery). Root canal surgery is done to preserve a tooth, but the surgery can fail or the tooth can fracture at a later date. If this happens, the tooth needs to be extracted.
