ABSTRACT:
A toothbrush is provided with bristles to brush and clean the teeth. Since there are cavities between neighboring teeth it is useful to exercise a multidirectional brushing of the teeth and cavities. The handle of the tooth brush is therefor provided with a fluid motor which is driven by fluid, for example by fluid from the water pipe which is available in the living quarters. The fluid motor revolves a rotary member wherein a space with a therein reciprocable piston is provided. The piston rod engages one end of a lever of a transfer arrangement and swings the lever. The other end of the lever then swings the outgoing shaft of the housing. By attaching a tooth brush to the swinging outgoing shaft the brush can do a multi directional movement for better brushing of the teeth and the cavities between the teeth.
