Revolving Tooth Brush
Especial efficiency in cleansing teeth is claimed for a new rotating tooth brush that operates with a spring mechanism. The brush, circular and of 1/2-inch diameter, is located at the end of an extension from the handle which contains the mechanism. The spring is wound with a handle which may then be folded flush and the mechanism is operated by pressing on a lever with the thumb. Practicing dentists aided in the design of the mechanism which, it is asserted, cleanses more thoroughly and more rapidly than the ordinary tooth brush.
