Abstract: A dental floss dispenser is disclosed, which may be adapted for insertion into an existing cavity found in pump type tooth paste dispensers, or the dental floss dispenser may be used separately without modification. The dental floss dispenser has a housing formed of a base, a circumferential wall extending from the base, and a cap secured to the circumferential wall. A chamber is thus formed between the base, the circumferential wall and the cap for rotatably receiving a dental flose spool therein. The cap has an aperture therethrough, and a hinged portion which may be raised or lowered; a knife blade is secured to the hinged portion in spaced relation from the aperture, and the dental floss is drawn through the aperture and closely received between the knife blade and the hinged portion, and biased to cut the end of the dental floss.
