A mechanism with a handle supports a pair of forwardly extending arms with a pair of guides flanking a flossing gap at the front of the tool. Clamp members anchor ends of a length of floss at the handle. An adjuster is moved to alter the length of the floss path in the tool so that the floss at the flossing gap can be configured as a straight line or in a loop with variable tension. A leverage bite member is mounted between the arms for sliding and rotating motion.
