Abstract
A holder for dental floss to be used in conjunction with a disposable cartridge on which the floss is mounted. The holder in one embodiment is an oblong handle having two spaced apart resilient substantially parallel legs which depend from a junction at one end of the handle. The one end of the handle has a bifurcated extension beyond the junction, and portions of the two legs are adjustably engaged with each other so that when the two legs are moved towards each other, the arms of the bifurcated end of the handle are stressed and spread apart from each other. An element including a length of dental floss is mounted on the bifurcated end of the handle so that when the arms are spread apart, the length of dental floss becomes rectilinear. The element typically is a cartridge having a U-shaped resilient frame. The length of dental floss extends between the opposed ends of the frame. In another embodiment, the length of dental floss extends between the ends of the arms of the bifurcated end of the handle and the arms are stressed away from each other so that the arms are spread apart and the length of dental floss becomes stressed and rectilinear.
