ABSTRACT:
A hydraulically operated toothbrush in which the flow of water from a faucet through the toothbrush handle and into the head produces rotation of a plurality of bristles mounted in the head, the bristles also being mounted for limited axially movement, and including a device for regulating the water pressure within the head to thereby assure the proper rotation of the bristles. The toothbrush may also include a siphoning tube operated by the suction created when water passes into the toothbrush, one end of the tube being inserted into the user's mouth and the other in a discharge basin. The siphoning tube may also be fitted with a mouth rinse fluid cup to introduce small amounts of fluid into the user's mouth during the brushing.
