Most oral perforation injuries caused by toothbrushes are considered to be minor and have a favorable outcome. On the other hand, even if the local findings are minor, there is a possibility of serious damage deep inside the mouth and serious complications may occur. Therefore, when removing a perforated toothbrush, the extent of damage must be accurately assessed by imaging studies. In this report, we describe a case of penetrating injury in which a toothbrush reached the posterior region of the mandible ramus. The patient, a 76-year-old woman, was injured when she accidentally fell with a toothbrush in her mouth while brushing her teeth after breakfast. The toothbrush perforated her buccal mucosa, and she was unable to remove it by herself, so she called for emergency medical assistance and was brought to our hospital. The toothbrush was removed under local anesthesia. Concerned about postoperative complications, the patient was hospitalized and managed. The patient was discharged on the third day of hospitalization because of good progress. About one year to date, the patient is doing well with no signs of infection or functional impairment.
