Abstract: An electric motor driven toothbrush is provided. The brush head of the toothbrush of the current application oscillates latitude to the body of the toothbrush. One end of a specially designed shaft, with an annular portion developed at that end, is connected to an electric motor via gears. A replaceable brush is attached to the other end. The circular portion at one end of the shaft is an annular plate that has at least two protrusions developed perpendicular to the circular plane. The two protrusions may be in a rectangular form or arc form developed along the perimeter of the circular portion developed on the shaft. A circular plate attached, with a predetermined angle, to a gear that vertically penetrates the annular portion enables a latitude oscillation movement of the brush head. With the toothbrush of the current application, a user can automatically scrub his/her teeth longitudinally along the length.
