Abstract
A dental floss for cleaning food particles and other material from between teeth. The dental floss includes a single strand of nylon material having a thickness of about 0.001 inches to about 0.003 inches and a width from about 0.025 inches to about 0.100 inches and has a tensile strength of about 31/2 pounds to about 25 pounds. The strand is extruded at relatively low temperatures which permits it to be readily colored and flavored. Further, it may be extruded into a plurality of shapes which may be chosen to enhance user comfort. The single strand of nylon material may include about 2% to about 20%, by weight, of a colorant; about 0.1% to about 3%, by weight, of a lubricant; about 0.1% to about 1%, by weight, of a plasticizer; or about 5% to about 30%, by weight, of a flavorant, fragrance, or combination of both.
