PROBLEM TO BE SOLVED: To protect bristles of a toothbrush, and to make correctable the spread of a tuft of bristles caused by using it. SOLUTION: A toothbrush set consists of a toothbrush and a correcting device, which is designed to put on the head of a toothbrush and has a groove to force bristles furnished on the head to the center. The correcting device has a space to put the head of the toothbrush in, and a pair of correcting plates for both sides of the correcting device, which press the bristles of the toothbrush from both sides of the width to the center, are located above the space and are provided from the entrance to the back. A groove-shaped opening, from which the upper end of the bristles of the toothbrush juts out, is formed at a gap between the pair of correcting plates.
