<p>Improved dental flosses include two or more components selected to provide desired properties to the floss. The improved flosses may comprise one or a plurality of multicomponent filaments, each filament including an inner core selected to provide strength to the floss, and an outer layer selected to provide a desired surface property. The improved flosses also may comprise one or a plurality of core filaments embedded in a single body sheath. The filament component provides desirable physical properties to the floss, such as tensile strength, while a floss body sheath component provides desirable surface properties.</p> |
