Abstract

An electrically powered device for cleaning the dorsal surface of the tongue, including a handle having a longitudinal axis, and an elongate member extending from the handle and terminating in a cleaning head adapted to reciprocate in a predetermined direction. An electric motor is provided within the handle adapted to operate at a predetermined frequency and thereby reciprocate the elongate member. The cleaning head includes agitation members and one or more cleaning members, such as elongate blades or banks of bristles. The agitation are arranged substantially perpendicular to the predetermined direction of reciprocation, while the cleaning members extend across the width of the cleaning head. The elongate member has a predetermined configuration that is tuned to resonate when reciprocated at a predetermined frequency, preferably within the sonic range, i.e. between about 1,000 and about 20,000 cycles per minute, thereby inducing a resonance action in the cleaning head. The arrangement of the agitation members and the resonance action result in a agitation cleaning effect that loosens plaque from within the surface of the tongue and substantially enhances cleaning thereof.
