PROBLEM TO BE SOLVED: To make fine contact with the surface of a tooth, to rake off stains in the fine recessed and projected surface of the tooth surface and to substantially improve a stain removing function to the tooth surface. SOLUTION: A tooth brushing implement 1 is constituted of a grip member 2 and a brush member 6. The brush member 6 is formed of a hard resin foamed molding, the whole is turned to a fine mesh-like structure, and the fine fluff 7 of hard resin is provided on a contact surface to the tooth. By the roughly same brushing method as the one of a normal toothbrush, the fluff 7 of the hard resin is brought into fine contact with the tooth surface, and the stains in the very fine uneven surface of the tooth surface are raked off by the fluff 7.
