  • Patent number: 4486914
    Abstract: A tooth brush is of generally tongs-like or horseshoe-like form with two arms that may be pressed elastically together for pressing brush members at their ends against the inner and outer faces of the teeth. The brush members are placed at an angle to the arms. In order to make possible full and complete brushing and care of the teeth, and more specially for the spaces between the teeth to be cleaned out and for the edges of the gums to be brushed and massaged, the brush members are each formed by a round brush with bristles running out from a support pin or core. The end of each support pin furthest from said arm has bristles directed towards the gums and gum edges.
