A dental floss holder includes a connecting section and at least four floss supporting arms extending from said connecting section. Each of the floss supporting arms has a first end and a second end. The first end is connected to the connecting section, and the second end includes a floss fastening portion for fastening a string of dental floss. The floss fastening portions of the at least four floss supporting arms are configured such that a string of dental floss attached to the floss fastening portions of the at least four floss supporting arms may be arranged to constitute the edges of a polyhedron.
