ABSTRACT:
An automatic toothbrush enables a user to brush all teeth of an arch simultaneously. A toothbrush portion includes a set of brushes arranged in an arc shaped to coincide with the shape of the user's mouth. The toothbrush includes side brushes for brushing the sides of the user's teeth, and occlusal brushes for brushing the biting surfaces of the teeth. All of the brushes are connected together by gears, so that rotation of one of the gears causes rotation of all of the brushes. The toothbrush includes a handle which contains a motor, the motor being connected to a drive shaft which engages one of the gears. The toothbrush also includes a display screen which is connectable to the handle, and which provides educational material or entertainment to the user while the toothbrush is in use. Also, the display screen may supply feedback to the user concerning the amount of plaque remaining on the teeth, or concerning some other aspect of the quality of the brushing
