A vibrating toothbrush comprising a handle including a body with a tubular member extending outwardly from one end. A replaceable sleeve slides over the tubular member and detachably engages the body. One or more of the sleeve, tubular member and body incorporates a vibration damping zone for reducing vibration transmission from the sleeve to the handle. The damping zone is one of a material that differs in damping properties to the material of the rest of the toothbrush; a hole defined in the one of the sleeve, tubular member and body, and a toothbrush where that hole is filled with an elastomeric material.
