Abstract
A rotary toothbrush includes a handle member to be held by a user; a head member having bristles and connected to the handle member; a tilting member, provided on the head member, for tilting upwardly the head member at a predetermined angle; a rotating member, provided on the handle member and the head member, for rotating the head member with respect to the handle member so that the head member is arranged in a T-shape with respect to the handle member; and a driving member for driving the head member to rotate and tilt the head member. With the rotary toothbrush, a user can freely brush his or her teeth in an upward and downward direction or in a left and right direction, and bristles can come into contact with a lower portion of front teeth to prevent dental plaque from getting buildup as much as possible.
