Claim:
A powered toothbrush comprising: a handle with a neck, a head mounted to said neck, said head having an exposed outer surface and a longitudinal axis, a first tuft block mounted to said head, said first tuft block having bristles extending outwardly from said outer surface, a second tuft block mounted to said head, said second tuft block having bristles extending outwardly from said outer surface, a drive structure for driving each of said first tuft block and said second tuft block in a counter rotational oscillation within a plane generally parallel to said exposed outer surface, and a third tuft block having bristles extending outwardly from said exposed outer surface, said third tuft block movably mounted to said head longitudinally outside of the first and second tuft blocks along said longitudinal axis at a position substantially between said neck and said first and second tuft blocks; wherein said bristles of said first tuft block and said bristles of said second tuft block define a pair of concentric circles of bristles that form a cup-like structure with an outer circle of bristles rotatable in a first direction and an inner circle of bristles rotatable in an opposing second direction; wherein the bristles of the third tuft block are embedded in an elastomeric material so as to be independently movable of each other when pressure is applied.
