Abstract
Disclosed herein is a rotating toothbrush including: a handle provided with a lever; a head part having bristles implanted on a lower surface thereof and a shaft vertically provided on an upper surface thereof; an operating rod provided in the handle and operated in conjunction with the lever to move linearly in a length direction of the handle; a tilting member rotatably supporting the shaft and pressed when the operating rod moves forward, thereby being tilted at a predetermined angle in an upward direction together with the head part based on a tilting axis; and a rotation driving member connected to the operating rod and the shaft to rotate the shaft when the operating rod moves forward, thereby allowing the head part to form a T shape with the handle. Therefore, the head part is tilted at a predetermined angle in the upward direction when the head part forms the T shape with the handle, such that bristles reach lower portions of lower front teeth, thereby making it possible to prevent generation of tartar as much as possible.
