Abstract
An improved housing for an electric toothbrush is disclosed. The improved housing provides two symmetrically positioned gripping members which assist the user in grasping the toothbrush particularly during brushing. Each of the gripping members includes a recessed gripping region having particular dimensional characteristics. The two gripping members are symmetrically arranged on the rearward sides of the toothbrush so that the brush may be used by both left-handed and right-handed individuals. A third gripping member may also be provided along the housing of the toothbrush.
