An improved dental floss employing a planar substrate with one or a plurality of apertures formed therein. At each aperture, a pair of edible substrate side portions having a perimeter portion slightly larger than the perimeter of the aperture are positioned and joined to each other through the aperture in the planar substrate thereby securing the edible substrate to the planar substrate. Dismounting of the edible substrate is achieved by tensioning the planar substrate around a tooth during use and aided by saliva dissolving the edible substrate. The edible substrate can be flavored or impregnated with medicine, mouthwash or flavorings. Additionally at least one of the two side portions of the edible substrate may include a design element which may include a geometric shape, a cartoon shape, indicia, or a logo.
