An 81-year-old man with a history of gingival bleeding presented with a fever, headache, and drowsiness. His mouth and full dentures were unsanitary. Laboratory tests revealed Streptococcus oralis meningitis caused by odontogenic bacteremia. We reviewed eight reported cases, including the present case, because S. oralis meningitis is rare. Our review indicated that S. oralis meningitis needs to be considered when encountering cases of a fever, disturbance of consciousness, and headache with episodes of possible odontogenic bacteremia.
