An improved dental flossing tool comprising a single flossing rod or tool is provided, containing a supply of dental floss therein and from which a strand of floss extends, and two hands are used, one to grip the flossing rod or tool, and the other to hold the free end of the floss strand at the proper angle and with the proper tension, with the second hand holding the free end of the floss strand. The floss tool of the present invention is preferably hollow, with a supply of dental floss mounted therein, and has a hollow, narrow tip through which the floss strand is routed internally to project from the end of the tip for use. A locking device is provided for selectively blocking the feeding of the floss strand in lengths which may be varied as desired and a restricting device is provided for restricting movement of the floss strand and for preventing moisture from entering the interior of the tool.
