Abstract

The floss is comprised of a plurality of polytetrafluoroethylene filaments and non-polytetrafluoroethylene filaments. The polytetrafluoroethylene filaments provide for a lubricity for the floss to enter more spaces and the non-polytetrafluoroethylene filaments provide for a case in gripping. In the way a range of polytetrafluoroethylene filaments can be used in the construction of a dental floss.
