Displacement of tooth is one of incidents in tooth extraction. We report a case of wisdom tooth displaced into oral floor and removed using an endoscope under general anesthesia at a later date. A 32-years-old man referred to our institution for extraction of bilateral mandibular wisdom teeth. Bone defect was detected at the lingual cortical bone around the left mandibular wisdom tooth by preoperative dental corn-beam CT. At the time of extraction of the left mandibular wisdom tooth, the tooth was divided into several pieces and the extraction was carefully performed, but a part of the tooth root displaced into the floor of the mouth. The displaced tooth was detected at the lingual side of mandibular by dental corn-beam CT. Since it was expected that direct vision of the displaced tooth would be difficult, the removal was performed using an endoscope under general anesthesia at a later date. After the operation, there were no adverse events such as lingual nerve injury due to surgery, and the course was good.
