Title: Toothbrush

Abstract: A toothbrush is disclosed which is capable of cleaning the buccal-labial and lingual surfaces of teeth simultaneously. The method of fabricating the toothbrush is also disclosed. The toothbrush includes a bristle mounting head, a holder for supporting the bristle mounting head and a plurality of cleaning bristles on the bristle mounting head, with the cleaning bristles being in the form of two arcuate or angular shaped bundles of nylon filaments, whose ends are spaced apart and opposed to each other. When the toothbrush is placed over teeth to be cleaned the tips of the bristles at the ends of the bundle rub against opposite surfaces of the teeth. The toothbrush may be made by winding a nylon monofilament around a mandrel an appropriate number of times, setting the windings to the cylindrical shape, bonding the windings together, removing the cylinder from the mandrel, cutting away a section of the cylinder and then attaching the remaining section of the cylinder to a bristle mounting head attached to a toothbrush holder, in one embodiment.
