SOLUTION: In these bunches 3 of about thirty bristles of 11 mm length implanted by two lines of ten places in a center and respectively one line of nine places on both sides of it (at 4 lines made of 38 places in total) in the shape of the grids of the toothbrush on the market, about 15 bristles at the outer periphery of each bunch 3 are cut into 7 mm length to manufacture the toothbrush. Otherwise, among the bunches 3 of about thirty bristles of 11 mm in length implanted by three lines of eleven places in a center and respectively one line of nine places on an outermost part (five lines made of 51 places in total) in the shape of the grids of the toothbrush on the market, odd-numbered bunches 3 of outermost line are cut to be 7 mm in length and concerning inner lines, the bunches 3 of the bristles at a position forming a zigzag with the outermost line are cut to be 7 mm to manufacture the toothbrush. Thus, this tooth brush can contribute to maintaining the teeth of the nation and can contribute to the health of the nation.
