PROBLEM TO BE SOLVED: To provide a dental floss holder to which the dental floss most suitable for a user among various kinds of marketed dental floss can be attached and which is widely improved in economy and reduction of wastes and is easily usable. SOLUTION: This dental floss holder comprises one or more heads and arms to support the heads. On at least one of the heads, a slit to pinch and hold the floss and a floss receiver to set a position to pinch the dental floss are equipped. A position of the slot to pinch the dental floss is determined not by receiving at the bottom of the slit but by the floss receiver. COPYRIGHT: (C)2006,JPO&NCIPI
