Successful endodontic management of teeth with odontogenic anamolies is quite challenging. Fusion is a condition where crowns of two individual teeth have been joined together during crown development. Though fusion occurs infrequently, it could predispose to caries and periodontal disease because of the abnormal tooth morphology. Here is a rare case of fusion of maxillary lateral incisor with a supernumerary tooth with a palato-gingival groove treated by multidisciplinary approach and its successful follow up.
