SOLUTION: A back tooth brush comprises two brushes, and the brush 1A and the brush 5B are mounted on the both edges in a condition that a central part is used as a handle 4. On this occasion, the brush 5B is same as a commercial brush, and the brush 1A is used for the back teeth. A head part 2 of the brush 1A is curved into the U-shape, so that the brush 1A can reach a rear face of the back tooth. Further as the other configuration, a brush has the shape same as that of a commercial one, but the brush 5 is designed to be smaller than the commercial one, and the points of the bristles of the brush is cut into the shape of an arch. Further a bellow-type curved part 7 is formed on a basic part of the brush 5, and a spring 8 is included in the same. When the brush 5 is used, the teeth are cleaned in the same manner as an ordinary brush, and then the curved part 7 is curved to brush the back teeth.
