Abstract
Abstract An elongated member has two like, forwardly, downwardly and outwardly extending prongs attached to its forward end slightly forward of an outwardly extending bore. In one embodiment, the member extends forwardly of a reservoir for receiving a spool of dental floss, and bears two opposed outwardly extending slotted posts. The forward end of each prong bears a hole, and a conventional dental floss cutter tab is disposed behind one post. In a second embodiment, the member and prongs are made of a flexible material, and the bore, posts, cutter and reservoir are omitted, with the hole in each prong being changed to a spiral slot.
