The head includes a first carrier coupled to the head and operatively connected to a drive mechanism for moving the first carrier in a first path of motion. The first carrier has at least one of a plurality of bristles and elastomeric cleaning members extending outwardly therefrom to deliver oral care benefits to the user. The head also includes a second carrier coupled to the head. The second carrier is formed of an elastomeric material and has at least one of a plurality of bristles and elastomeric cleaning members extending outwardly from an upper surface thereof. The second carrier is constructed so that upon application of a force to the upper surface thereof, the second carrier moves in a second path of motion that is different from the first path of motion.
