The toothbrush having a main body, a power system housed in the body and a brush inserted into the power system to vibrate for brushing action, includes a drive motor, a rotary disc wheel geared all round, coaxial 1st and 2nd cams, a horizontal motion cam following the 2nd cam, an eccentric cam being coaxial with the geared wheel, a half circular cam, a shaft connector for delivering tracked movement of the horizontal and vertical cam, a brush insert receiver shaft extended from the connector. The associated mechanism of the eccentric cam and the revolutionary cam actuates the brush for rolling movement, vertical movement, Bass brushing, Fon's brushing, and circular track movement for oscillation. The brush is replaceable and generates low noise in oscillation.
