ABSTRACT:
An electric flossing apparatus comprising a flossing head which is detachably connected to a handle containing a reciprocating drive unit, a non-powered second handle to allow for the increased controllability of two-handed powered flossing and a disposable floss assembly that can be easily be attached to or released from the flossing head and handle. The floss is releasably attached to the flossing head in a manner that allows reciprocating motion to be imparted along the length of the floss no matter which direction that the floss exits the end of the flossing head or the shape of the path it takes. By using both hands for flossing the floss may be pulled straight and tensioned to facilitate insertion between tightly spaced teeth and then wrapped around a tooth to facilitate cleaning of the front, sides, and back of each tooth above, near, or just below the gum line. The reciprocating motion is imparted to the floss whenever the floss is tensioned. The intensity of the motion is then controlled by the amount of tension and the “rigidity” of the users grip on the two handles. The drive unit handle assembly may be from an inexpensive commercially available electric toothbrush such as a Crest Spinbrush™.
