A replaceable accessory head for a powered toothbrush. The user selects one of a plurality of dental care accessory assemblies for flossing, brushing teeth, or for stimulating the gums. That assembly is engaged with the head which in turn is engaged with the handle and is locked thereto. This locking motion 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 is worn out or when a different dental hygiene task is to be undertaken, the user detaches the head from the handle, thereby simultaneously unlocking the accessory assembly from the head. The assembly is then disengaged and is replaced by a different accessory assembly.
