What is claimed is: 1. Coated multifilament dental floss having a denier between about 300 and about 1000, said floss having two distinct coatings, including: (a) from between about 10 and about 100 mg/yd of base coating selected from the group consisting of saliva soluble coatings and saliva insol

What is claimed is: 1. Coated multifilament dental floss having a denier between about 300 and about 1000, said floss having two distinct coatings, including: (a) from between about 10 and about 100 mg/yd of base coating selected from the group consisting of saliva soluble coatings and saliva insoluble coatings, and (b) further including a biofilm-responsive particulate abrasive overcoating thereon and at least partially imbedded in the base coating, wherein said particulate abrasive overcoating comprises from between about 2 and about 45 percent by weight of said device; and whererin from between about 20 to about 90% of the total surface of each particulate in the overcoating is imbedded into the base coating on the multifilaments. 2. A coated multifilament dental device according to claim 1, wherein said imbedded biofilm-responsive particulate abrasive overcoating has an average particle size from between about 7 and 200 microns. 3. A coated multifilament dental device according to claim 1, wherein said imbedded biofilm-responsive particulate abrasive overcoating has a particle size distribution from between about 5 and about 300 microns. 4. Coated multifilament dental devices according to claim 1, wherein said overcoating also contains additional solid particulates selected from the group consisting of water soluble waxes, water soluble nonionic surfactants, an emulsion of polydimethyl siloxane and polyoxypropylene-polyoxyethylene block copolymers, a high shear mixture of high molecular weight block copolymers of ethylene oxide and propylene oxide with high viscosity polydimethylsiloxane polymers and mixtures thereof. 5. Coated multifilament dental devices according to claim 1, wherein said multifilament dental floss is selected from the group consisting of texturized, untwisted, tacked, twisted multifilaments and mixtures thereof. 6. Coated multifilament dental devices according to claim 1, wherein said coating contains a releasable antimicrobial. 7. Coated multifilament dental devices according to claim 1, wherein said biofilm-responsive particulate abrasive overcoating is a dental abrasive selected from the group consisting of silica, pumice, alumina, calcium carbonate, dicalcium phosphate dihydrate and mixtures thereof. 8. Coated multifilament dental devices according to claim 1, wherein said biofilm-responsive particulate abrasive overcoating is an active abrasive selected from the group consisting of whitening, tartar control, stain fighting, hypersensitivity treatment abrasives and mixtures thereof. 9. Coated multifilament dental devices according to claim 7, wherein said multifilament dental devices contains from between 2 and 12 multifilament bundles. 10. A coated multifilament device according to claim 1, wherein said multifilament construction is selected from the strand types consisting of: 140 denier and 68 filaments, 100 denier and 34 filaments, 70 denier and 34 filaments, and combinations thereof. 11. A coated multifilament dental device according to claim 1, wherein said base coating is saliva insoluble and said biofilm responsive particulate abrasive overcoating is insoluble.
