A dental floss apparatus for cleaning the gaps between adjacent teeth which is comprised of a pair of handles that are configured for engagement with the fingers with strands of flossing substrate extending therebetween. The flossing substrates are spaced from each other, running substantially parallel and extending within an opening formed between the ends of the handles, with tension maintained by the user through employment of the handles. A dissolvable substrate is positioned within this opening through an engagement with one or both of the handles or the flossing substrate, and upon contact with the surface of the teeth, dissolves, and deposits a residue on the surface of the teeth and the surrounding area of the mouth. The dissolvable substrate may be formed of two substrate pieces with a central gap between them defining a means for targeting insertion of the substrate between adjacent teeth and may be colorized or fluorescent, and have an additive material such as mouthwash, breath freshener, cooling agent, or flavor.
