The device of the present invention is a split head toothbrush having a powered mechanism that actively causes the two portions of the split head to move relative to each other. The toothbrush includes a camshaft that is operationally connected to a motor in the handle of the brush. The camshaft extends through the neck of the brush and into the head, terminating in the head at a point beneath the bristles. The camshaft has two offset cam lobes that contact both of the portions of the split head. As the camshaft rotates, the cam lobes cause the portions of the split head to move upwardly and downwardly relative to each other. The head of the toothbrush may be permanently attached to the handle or may be selectively detached therefrom.
