ABSTRACT:
A power driven brush assembly for cleaning teeth or the like. The brush assembly is formed with a hollow handle element containing drive means coupled to a power transmission extending from the handle element through a handle extension which carries a plurality of brush supporting members remote from the handle element. A plurality of brushes, one for each brush supporting member, is provided, with at least one of said brushes contoured with a cup-shaped cavity at a free end thereof remote from said brush support to implement the facility with which the outer edges of the brush may be bent to approximate the contours of the surface to be brushed. A method based on the same inventive concept is also disclosed for implementing the facility with which a surface may be brushed. This is accomplished by forming a plurality of brushing members with relatively unrestrained brushing portions free to flex to and from a longitudinal axis of the brushing member, and mounting the brushing members for rotation about the longitudinal axis thereof; and thereafter driving the brushing members to bring the relatively unrestrained brushing portions over the surface to be brushed with adjacent brushing members rotating in opposite directions.
