The brushhead (14) includes a neck portion (15) which connects at a proximal end thereof to a handle portion (12) of a power toothbrush (10). At the distal end of the neck portion is a brush member (16, 28) which includes a bristle base plate (18, 34) and a bristle field (20, 36) mounted thereon. An eccentric (30) is mounted for spinning action on the bristle base plate, positioned in the midst of the bristle field. An eccentric bristle field (38) is mounted on the eccentric. The motion of the brush member produced by a toothbrush drive assembly creates a spinning motion of the eccentric and the eccentric bristle field mounted thereon, resulting in additional oral cleaning action. |
