Abstract: A dental floss device includes an elongated clam shell body having top and bottom halves joined by a hinge at a bottom and having a closed position during operation and an open position to access a spool with floss therein; a pair of spaced apart prongs extending from one end of said elongated clam shell body, each prong receiving floss threaded therethrough; a ratchet coupled to the spool to prevent turning of the spool when engaged; and a button on one surface of the clam shell body that releases the ratchet and allows floss to be dispensed and engages the ratchet when the button is released to hold the floss.
