ABSTRACT:
An elongated tooth brush handle houses a motor at the bottom of the handle. The motor output shaft is surrounded by an inner magnet which in turn is coupled to an outer magnet. When opposite poles face each other the inner magnet will turn the outer magnet. The outer magnet turns on a bearing which will give it longitudinal motion. The outer magnet is coupled to flexible shaft which passes out of the head of the handle to an output coupling through a slit in the handle head. A small rotary brush can be affixed to the output coupling.
