A hand-holdable flossing device is provided for dispensing and supporting a selected length of dispensed dental floss for use in an operational position within an oral cavity. In general, the flossing device has a front end and a rear end, and an elongated gripping surface extending therebetween for encirclement within a user's hand. The handle portion has a hollow cavity for containing a supply of dental floss, and a passageway formed in the front end and in communication with the hollow cavity to permit passage of dental floss from the hollow cavity through the passageway. The dispensing portion has a base portion operably associated with an elongated portion which extends in an essentially linear direction and terminates in a tip portion. The base portion, elongated portion and tip portion has a continuously extending dispenser bore formed therethrough which permits dental floss to slidably pass from the passageway through the base portion and said elongated portion and exit from the tip portion. Dispensing portion can be operatably connected to the handle portion in a variety of ways, including a bayonet-type or screw-thread type interconnection, each of which permits rotatable arrangement of the dispensing and handle portions into a floss locking configuration and a floss releasing configuration. In both embodiments, a selected length of dental floss is permitted to be pulled through said dispenser bore and dispensed from the tip portion when the handle portion and the dispenser portion are rotatably arranged into the floss releasing configuration. Also, the selected length of dispensed dental floss is locked and restrained from being pulled through the dispenser bore when the handle portion and the dispensing portion are rotatably arranged into the floss locking configuration.
