This article reports the treatment of a maxillary left central incisor geminated with a supernumerary tooth. A patient having labial swelling around the maxillary incisors was referred to this hospital for diagnosis and endodontic treatment of the maxillary left central incisor. Clinical and radiographic examinations revealed a tooth having two roots and three canals. Examination of a rubber base impression of the cleaned canals showed there was neither perforation of, nor communication with, the radicular groove in the tooth.
