  • Patent number: 5137039
    Abstract: The device and method employ a pair of spaced jaws which have a tooth cleaning implement connected therewith, in the gap therebetween. In use, the jaws are straddled about a row of teeth, transverse thereof, and translated along the row opposite the inside and outside faces of the teeth. Various features enable the user to locate and "steer" the device, even when the jaws and implement are out-of-sight to him. Other features enable the user to count on the device itself to provide the "dynamics" with which we commonly use a conventional "tooth brush" when we manipulate it in our mouths from a point thereoutside. Still others enable the user to program or predetermine the "grip" of the device, transverse of the row, and to do so, moreover, in the context of having an interchangeable or replaceable tooth cleaning implement thereon which is adjustable in "grip" each time a new implement is substituted for an old.
