An abrading dental floss is characterized by dental floss formed of a circular fiber or fibrous material having a dental abrasive on the exterior portion thereof suitable for polishing, sanding and/or finishing (abrading) dental restorative material particularly dental composite resin. The dental abrading material is impregnated into or provided onto the dental floss. In one form, the dental abrading floss has an abrading section situated between lengths of non-abrading dental floss. The abrading section may be formed of an alternating pattern of non-abrasive portions and abrasive portions along a length of the floss. The abrasive portions may be of a single grit or texture of the dental abrasive or may be of different grits of the dental abrasive. In another form, the dental abrading floss has a single grit of a dental abrasive along and about its entire length. The dental abrasive may be of a single grit or different grits of the dental abrasive along its length. For different grits of the dental abrasive, it is preferred, but not necessary, that they gradually change in grit size.
