A powered toothbrush is provided with a pair of disc-like rotary brushes mounted for rotation about a axis generally perpendicular to the length of the brush. The rotary brushes are in axially spaced relationship and are provided with inwardly directed bristles. Between the rotary brushes, upper and lower linear brushes are mounted above and below the axis of rotation for linear reciprocating motion generally perpendicular to that axis. The upper brush has upwardly directed bristles, and the linear brushes are mounted to the rotary brushes so as to be brought into reciprocal, linear movement when the rotary brushes are reciprocated angularly.
