Abstract: The present invention relates to a toothbrush head which is constituted by a body, a first rotation pipe, a drive unit, a support, a rotator, and an auxiliary rotator and can clearly wash every nook and corner of teeth and wash upper teeth and lower teeth at once only by a method that just slightly bits a part of a body unlike the existing tooth brushing method in which a user brushes his/her teeth by rapidly moving his/her hand left and right and up and down and right to reduce a tooth brushing time. As a correct washing method of the teeth, only when the teeth are brushed while rotating a toothbrush vertically from an upper side to a lower side of the teeth, food wastes can be easily removed and an injury of gum parts connected with the teeth due to wrong tooth brushing (tooth brushing performed in a horizontal direction of a set of teeth) can be prevented and the present invention is configured to be suitable for the tooth brushing.
