ABSTRACT:
A dental floss holder is provided with a slot-headed locking axle on which a spool of floss is mounted. A length of floss is extracted from the spool disposed within the holder and is spanned across two spaced prongs formed on the holder and locked to the axle by being wound about one side of the slotted head before spanning and the other side of the slotted head after spanning. Tension is applied to the spanned floss by rotating the locking axle which is held in position by a ratcheting spring clip to provide a taut span of floss which can be manipulated between the user's teeth.
