The present disclosure provides an oral cavity cleaning device with which an inside of an oral cavity can be cleaned more efficiently. The oral cavity cleaning device according to the present disclosure includes a tank configured to store a liquid, a nozzle to which the liquid stored in the tank is configured to be discharged into an oral cavity, a pump configured to suck the liquid stored in the tank and discharge the liquid through the nozzle, and a pump drive mechanism configured to drive the pump. The pump comprises a piston which is configured to be reciprocated linearly in one direction. In the pump, a suction step of sucking the liquid into the pump and a discharge step of discharging the liquid from the pump are alternately performed by a piston which is configured to be reciprocated linearly. The piston is configured to be reciprocated once such that a period of time taken for the suction step and a period of time taken for the discharge step are different from each other.
