Abstract: A dental floss cleansing device which includes a floss chamber connected by a neck to a bow frame spaced from the chamber. The bow frame includes a post projecting from a proximal end of an elongated shaft having a curved distal end. The shaft is centrally grooved for floss guiding purposes. A debris protective shield extends from opposite sides of the shaft over a major portion of its length. A floss strand extends from the floss chamber along the floss guiding groove in the shaft to the curved distal end of the shaft. The floss strand extends in a bight back to the post, and is there secured.
