  • Patent number: 4330014
    Abstract: A holder is provided which contains at least two different flossing materials. The one material is typically unwaxed dental floss. The other material varies in thickness and is selected so as to provide, when doubled over, the appropriate thickness to be presented between the interdental spaces to accomplish the proper cleansing of the interdental area. Various multi-stranded materials are provided for selection to be placed in the holder. Multi-stranded cotton embroidery thread may be used. The one material which is fairly thin and is unwaxed or waxed dental floss or even waxed tape is used so that it can be worked between the contacts of the teeth. The multi-stranded material will be used for the primary cleaning. The placement of the cleaning material between the interdental area is accomplished as follows: A loop of the thin material is interlocked with a loop of the thicker material.
