A powered, vibrating toothbrush from which ultra-violet radiation is emitted at the bristle end. The bristles are carried on the end of a tubular shank projecting from a handle. A radiation emitting lamp tube is enclosed within the shank, the lamp tube being coated with a radiation blocking material except at its end portion aligned with the bristles. The source of electrical energy in the handle energizes the vibrator and the lamp tube.
