Abstract (en)
[origin: DE4402366A1] The invention pertains to details of electric toothbrushes whose stems (1) are fitted with double, spring, bristle-holding heads (32) which in four axes and planes provide an all-around resilient action in the various types of application to the teeth. In addition, a variable vibration is induced in the bristles (24) from a handle (10). The bristles (24) are set in the brush heads in bundles of conical shape (22) designed to reach the spaces between the teeth, for non-traumatic care of the teeth and gums.
