A flossing tool includes a handle, a neck and a head at the distal end of the neck. A spool of floss is placed in a compartment within the handle with the free end of the floss being extended from the compartment and over a series of ridges traversing the neck. The floss is wound about four lobes on the head so as to present first and second laterally spaced-apart stretches of floss. The free end of the floss is then wound about a pin on the neck so as to place initial tension on the wound floss. A locking device engages the ridges on the neck so as to clamp the dental floss to the neck and place additional tension on the wound floss. Accordingly, first and second opposed stretches of tensioned floss are available to clean the upper and lower teethlines. A cutter blade on the neck allows the user to sever the end of the floss upon use. The angles between the handles, neck and floss head are selected so as to assist the user in flossing.
