PROBLEM TO BE SOLVED: To provide a compact and easily portable oral cavity cleaning device which removes bacterial plaque and food residues stuck in an interdentium effectively by discharging compressed air or compressed liquid in the form of a jet into the oral cavity from the apex of a nozzle and is used easily without going to a specialized facility such as a dental clinic. SOLUTION: A piston 6 fit in a cylinder 5 in an airtight and reciprocative manner is reciprocated by a manual operation. The compressed air is retained in an air bottle 3. The bacterial plaque and food residues stuck between the teeth 85a are removed by discharging the compressed air (or the compressed liquid) in the form of the jet from the nozzle 4, and the inside of the oral cavity 85 is cleaned effectively.
