Abstract
A dental floss holder including a pair of arms, each arm having a middle portion and first and second opposite end portions. The first end portion of each arm curves outwardly away from its respective middle portion wherein the middle portions of the arms are positioned proximate one another so as to define a pivot. The second end portions are movable between a first position in which the first end portions of the arms diverge away from one another, and a second position in which the first end portions are moved toward one another. Dental floss material has one end secured to the first end portion of one arm and an opposite end secured to the first end portion of the other arm. The dental floss material has a first tension when the first end portions are in their spaced apart position and a second tension when the first end portions are moved toward one another, said first tension being greater than the second tension. Also disclosed is a filament, such as a dental floss, that contains fumed silica. The dental floss may be used alone or with the disclosed dental floss holder.
