1. A toothbrush head comprising:
a first dental tray having a longitudinal axis, the first dental tray including a first set of cleaning surfaces for simultaneously cleaning multiple tooth surfaces of a first set of teeth, and a plurality of flex hinges permitting flex of the first dental tray orthogonal to the longitudinal axis, each in the form of a gap extending from an outer edge of the first dental tray into the first dental tray;
a second dental tray having a longitudinal axis, the second dental tray including a second set of cleaning surfaces for simultaneously cleaning multiple tooth surfaces of a second set of teeth, and a plurality of flex hinges permitting flex of the second dental tray orthogonal to the longitudinal axis, each in the form of a gap extending from an outer edge of the second dental tray into the second dental tray;
a driving mechanism;
a frame retaining the driving mechanism;
a first paddle interposed between the first dental tray and the driving mechanism and attached to the driving mechanism;
a first gimbal coupling the first dental tray to the first paddle and allowing for a limited freedom of movement of the first dental tray relative to the driving mechanism;
a second paddle interposed between the second dental tray and the driving mechanism and attached to the driving mechanism; and
a second gimbal coupling the second dental tray to the second paddle and allowing for a limited freedom of movement of the second dental tray relative to the driving mechanism.
