The incidence of supernumerary teeth appearing in the third molar tooth regions is reported to be 0.02～2.2%, and while most of which are found in the unilateral maxilla, they rarely occur in the mandible, and bilateral mandible occurrence is extremely rare. Here we report a case with the supernumerary teeth distal to the third molar teeth in the bilateral mandible. The patient was a 27-year-old man who was found to have maxillomandibular third molar teeth and supernumerary teeth in the bilateral mandible, and visited our department for teeth extraction. Panorama radiograph and CT images showed that the patient had an impacted supernumerary tooth above a horizontally impacted wisdom tooth in his right mandible. He also had an impacted wisdom tooth and a buccolingual impacted supernumerary tooth in the left mandible. We removed the bilateral maxillomandibular third molar teeth and the bilateral mandibular supernumerary teeth under general anesthesia management to prevent infection. About five months have passed since the operation, and no infection or incomplete healing of the extraction sockets has been observed, and the course is good.
