A hand-held flossing tool provides a housing member having a spool housing integral therewith containing a replaceable spool of dental floss, a tension head consisting of two tension arms integrally molded to a yoke, each tension arm including a snap eye on one end and a gripping surface at the other end, and a stabilizer rotatably attached to the housing member. The dental floss strand, which passes from the housing through a spool housing slit and then through the snap eyes on the tension arms, is secured around a cleat on one of the tensions arms. The flosser places the stabilizer in the flosser's palm and holds the tension arm gripping surfaces between the flosser's thumb and index finger. The floss spool ratchets within the spool housing to permit adjustment of the tension on the strand of dental floss by rotation of a tension adjustment key extending through the bottom of the housing into the spool. A further adjustment of tension on the dental floss strand is provided as the flosser varies the force applied to the tension arm gripping elements. A removable cap on the spool housing permits replacement of a depleted dental floss spool. The cap is sealed to the top of the spool housing by a compression seal to prevent moisture from entering the spool housing. The tension adjustment key includes a barrier which resists entry of moisture and contaminants through the tension adjustment key access in the bottom of the spool housing.
