Abstract: An integrally formed dental floss and leader which lends itself to oral prophylaxis especially for implants and bridges. The floss is captured by the leader through a hinged door which swings from an open to a closed position during fabrication to provide an integral unit for use by a floss user when closed. A leading portion of the door fits flush within a complementally formed support channel within a tethered end of the leader. A trailing portion of the door projects with an extension of a floor of the support channel, defining a tongue, to provide a floss support. A hinge defines a transition between the floor extension and the door. The hinge allows the door to pivot about the floss and enter the support channel with the floss interposed between the door and the tongue. Shoulders border the support channel providing reinforcement to the tethered end.
