A full hands-free automatic toothbrush is disclosed for brushing all user's teeth simultaneously without holding by hands, thereby enabling the user to engage in other activities while brushing teeth, is more effective cleaning and shorten time for brushing. The full hands-free automatic toothbrush includes an jaw mould which be structured to hold the brushing bristle wires inside and can cover all the user's teeth when closing two sets of teeth. The full hands-free automatic toothbrush includes a handle which contain a source of energy and an electric motor. In some embodiments the full hands-free automatic toothbrush includes the brushing bristle wires for easy rotating around its axes and replacement. In some embodiments includes a handle for easy insertion and removal. Other embodiments include a button (two levels) or small lever (either direction) on the handle for driving bi-directional (forward and backward) to the motor.

Embodiments of the present invention comprise a powered toothbrush comprising a bristle head, an outer gear, and a plurality of bristles. Both the bristle head and the outer gear may comprise a distal end, a proximal end, and a center. The distal end of the bristle head may mate with the proximal end of the outer gear. The outer gear may rotate about a first axis of rotation. The mating between the bristle head and the outer gear may cause the bristle head to orbit the first axis of rotation via one or more bristle paths while simultaneously completing one or more rotary movements about a second axis of rotation, which may move along the bristle paths with the bristle head.

Described herein are electronic dual-head tooth cleaning appliances that facilitates simultaneous front and rear surface cleaning of individual teeth. The tooth cleaning appliances or devices can be rechargeable, portable, lightweight and electronic.
