ABSTRACT:
An electric toothbrush in which the brushing head moves in an elliptical motion such that, on the brushing stroke, the bristles are proximate the teeth, and in the recovery portion of the cycle the bristles are pulled away from the teeth. A position sensitive switch automatically switches from a forward to a reverse operation of the electric motor, depending on the positioning of the toothbrush in a user's hand, allowing the user to brush both the upper and lower teeth using a stroke carrying the bristles from the gum line to the ends of the teeth, as is recommended by dental professionals, without having to move the toothbrush from hand to hand or manually move the switch from the forward to the reverse positions. A bridge pad engages the face of the teeth, maintaining a proper distance between the teeth and bristles during the elliptical rotation of the brush head.
