Abstract

The present invention relates to an improved device and method for flossing teeth. The device has a handle portion and a finger portion. The finger portion is inserted into an individual'"'"'s mouth, and the handle portion is used for holding the dental flossing device. In a first embodiment, the dental flossing device has two apertures spaced along the finger portion. The flossing material is threaded through the first aperture and then the second aperture. A user presses one end of the flossing material against the device to keep the flossing material taut. The other end of the flossing material, extending from an aperture at the distal end of the device, is held by the user'"'"'s fingers or is wrapped around a finger, depending on the individual'"'"'s personal technique. Thereafter, the finger portion of the device is inserted into the mouth and flossing is performed. In a second embodiment, the device has only a single aperture through which the floss is threaded, a section of the floss being held against a side of the device by the hand of the user during use.
