<p>A replaceable accessory head (24) for a powered toothbrush (20). One of a plurality of dental care accessory assemblies (64) is selected for flossing, brushing teeth, or for stimulating the gums, which is engaged with the head (24) that in turn is engaged with the handle (22) and locked thereto. This also causes the assembly to become locked to the head and the assembly may then be used for its intended purpose. A vibratory mechanism in the handle is activated causing vibration in the accessory assembly and thus improving the flossing, brushing or gum stimulation motions. When the assembly (64) is worn out or when a different dental hygiene task is to be undertaken, the user detaches the head (24) from the handle (22), thereby simultaneously unlocking the accessory assembly from the head. The assembly is then disengaged and is replaced by a different accessory assembly.</p> |
