Abstract: A wall mounted dental floss dispenser is disclosed. The dispenser includes a mounting bracket supporting a housing. Within the housing is a vertically oriented plate having a recess for supporting a known replaceable pocket floss dispenser. Floss is guided downwardly to be engaged by a pair of nip rollers, one of which is manually rotated to advance the floss to an outlet opening in said housing adjacent a cutting blade. Use of the device enables the obtaining of a desired length of floss using only a single hand of the user.
