A toothbrush includes a head and a tooth cleaning element extending from a top surface of the head. The head is divided into at least two portions which can be moved independent of each other. The tooth cleaning element is rotatable relative to that portion of the head from which it extends. A vibrator vibrates the head and tooth cleaning element.
