An oral cavity cleaner is disclosed. The present invention comprises: a conveying tube for conveying cleaning water supplied from the outside; a spray nozzle part for spraying cleaning water into the oral cavity of a user; and a water supply control module installed between the conveying tube and the spray nozzle part to control the supply of cleaning water to the spray nozzle part, wherein the water supply control module includes a first water-passing space in which cleaning water is stored when a button part is not pressed by the user, and a second water-passing space into which cleaning water stored in the first water-passing space is conveyed according to that the button part is pressed by the user in order to spray cleaning water. According to the present invention, despite the high water-pressure of cleaning water supplied to an oral cavity cleaner, a user can operate a spray button for controlling spraying of cleaning water even with a small force.
