PURPOSE: An oral cavity sterilization cleaner is provided to cleanly remove foreign material between teeth and to massage the gum. CONSTITUTION: An oral cavity sterilization cleaner comprises a water bottle part(4), a piston pressing part, a sterilization filter part, and a spray nozzle part(8). A series of piping is consecutively connected to the end of the spray nozzle from the water bottle. The water flowing through the bottom part of the check valve of the water bottle changes the rotational plate connected to a motor shaft into a linear motion. Pressure is periodically applied to flowing water by using the oscillation of a piston.
