A dental flossing tool for dispensing floss for cleaning the user's teeth. A handle body surrounds a cavity and has a lead riser from which dental floss is dispensed for use. The floss is wound upon a spool that rotates inside the cavity. Floss is paid out from the spool and emerges from a hole in the tip of the lead riser. A button or handle is slidably mounted upon the apparatus for controlling the longitudinal movement of a retainer within the cavity of the apparatus. By sliding the button handle forward and backward, the user can disengage and engage the retainer with a baffle attached to the spool inside the body of the apparatus. When the retainer is in contact with the baffle, the spool is prevented from rotating, thereby stopping any further floss from being dispensed. When the retainer is disengaged out of contact with the baffle, the spool is free to rotate to pay out floss. A removable protector is provided for covering the lead riser and a floss cutter blade attached to the exterior of the apparatus. The protector can be removed to the back end of the apparatus to extend its graspable portion for easier handling.
