A tooth cleaning device, comprising a tooth socket, a liquid supply system, a gas supply system, and an electric control system. The tooth socket comprises an upper tooth socket (1) and a lower tooth socket (2)； the upper tooth socket (1) and the lower tooth socket (2) are respectively provided with an upper groove (3) and a lower groove (4), which are applicable to holding teeth. The upper tooth socket (1) or the lower tooth socket (2) is further provided with an injection port (5) used for filling with external tooth cleaning liquid； the injection port (5) penetrates into the surface of the upper groove (3) or/and the lower groove (4)； a liquid flow passage (6) for communicating the upper groove (3) with the lower groove (4) is provided between the upper groove (3) and the lower groove (4). In the upper tooth socket (1) and the lower tooth socket (2), gas filling pipes (7) are provided in sequence in a penetration manner along edges of the upper groove (3) and the lower groove (4)； the gas filling pipes (7) can be expanded along with the filling of gas, so as to fill gaps among the edges of the upper groove (3) and the lower groove (4) and the gingiva. When the tooth cleaning device is used, the tooth cleaning liquid can flood all surfaces of the teeth and quickly flow through, enabling residue food on all the surfaces of the teeth to be washed away, thereby achieving a complete tooth cleaning effect.L'invention concerne un dispositif de nettoyage dentaire, comprenant une alvéole dentaire, un système d'alimentation en liquide, un système d'alimentation en gaz et un système de commande électrique.
