Abstract
A tool of the type using dental floss having a handle to which are joined two double-pronged members. Each member is structured to anchor two ends of a run of floss with a length of the run extending between the tips of the associated prongs. When lengths of floss are received by the two pairs of prong tips, these lengths are in spaced-apart, generally parallel, confronting relatioship. In the preferred embodiment, the two floss lengths are relatively adjustable to the extent that one floss length can be moved laterally past the other. Spring biasing is used to hold the floss lengths in predetermined positions relative to one another when in a relaxed state. Other desired positions are achievable through application of appropriate forces.
