Abstract
A water powered rotary toothbrush is provided which includes a housing having inlet and outlet ports and a rotatable center shaft. The rotatable center shaft has one end provided within the housing. A paddle wheel is located in the housing and is fixedly attached to the shaft near the one end thereof. The opposite end of the shaft extends out of the housing and has removably attached thereto a rotary brush element. Water is introduced into the housing through the inlet port where it is directed against the paddle wheel causing it and the center shaft to which it is fixedly attached, to rotate. The rotation is translated to the brush element which likewise rotates. Excess water is removed through the outlet port.
