ABSTRACT:
A dental floss product and a method for making the same. A texturized dental floss substrate having a plurality of strands is provided. Each of the strands is formed from a plurality of individual filaments. At least one of the strands in the substrate contains filaments which were curled, looped, twisted, bent or crimped prior to their incorporation into a strand. The texturized dental floss substrate has an indefinite length, a cross-section perpendicular to the length, an exterior surface, and a depth defined as the distance from the exterior surface toward the center of the cross-section. The texturized dental floss substrate also has a substrate weight and an overcoating applied to the exterior surface. The overcoating is formed of a carrier and at least one adjuvant, and has a weight which exceeds 10% of the substrate weight. The concentration of the overcoating decreases in a direction from the outer surface of the floss toward the interior, i.e., the concentration of the overcoating is greater at the exterior of the coated floss and lesser in the interior region thereof.
