Abstract

Abstract Porous, high strength (that is, "Expanded") polytetrafluoro-ethylene (PTFE) dental floss is coated with microcrystalline wax. If desired, the floss may also incorporate one or more active tartar control, anti-caries, antiplaque and/or antibactrial actives and/or dentally acceptable agents such as polishing and abrasive agents, coolants, flavorants and/or coagulants.
