发明名称 Multi-surface toothbrush
摘要 The present invention consists of a toothbrush with multiple tooth cleaning surfaces that allow the simultaneous cleaning of two or more tooth surfaces. In the preferred embodiment, there are three tooth cleaning surfaces, one each for the front, back, and top of the teeth. The tooth cleaning surfaces for the front and the back surfaces of the teeth comprise bristles mounted on surfaces that are movable towards and away from each other to compensate for the varying thicknesses of teeth. The handle of the toothbrush may be pivotably or detachably attached to the head of the toothbrush.
