If the molar tooth is fractured longitudinally, it is usually necessary to extract the affected tooth or amputate the root of the tooth, and after the alveolar bone has been stabilized, restorative treatment will be carried out to restore the function of the tooth.
1. Extraction of the affected tooth: Generally, the affected tooth with obvious looseness, weak bite and repeated swelling of periodontal soft tissues needs to be extracted.
2. Amputation of the affected root: if the molar is a multi-rooted tooth, if the crown-root ratio, root bifurcation width, the relative level of the root bifurcation and the alveolar bone, the periodontal condition is still good, the tooth is still solid, and the X-ray shows that the destruction of the alveolar bone is confined to the root of the tooth which is longitudinally fissured, the amputation of the root of the affected tooth, i.e., the removal of the diseased portion of the root, and the other half of the tooth with the relatively good tissues, then the endodontic and subsequent restorative treatments will be carried out.
Longitudinal fracture of a molar tooth is recommended to be treated under the supervision of a doctor.
