Abstract

A flossing instrument 10 that facilitates flossing and is utilizable by persons fitted with common orthodontic braces. The instrument 10 includes a combination floss spool cavity 22 and handle 20 to which is connected an arm 50 with two floss supports 100, 140 traversely mounted at a distal end 54 of the arm 50 remote from the handle. One support forms a tower 100 which is replaceable and interchangeable with a multitude of possible supports of differing functional applications. The tower 100 fits in the limited space between an orthodontic arch-wire W and the adjacent teeth T to be flossed. The instrument 10 includes a means to tension the floss F, a means to advance the floss F across the supports 100, 140, and results in a floss F action that uniquely moves through the adjacent teeth T at an angle while continually advancing new floss F'"'"'. Use of this instrument 10 provides a flossing process that is gentler and more controlled because the instrument 10 remains stationary when the floss F overcomes the tightest spacings between adjacent teeth T. The instrument 10 accomplishes flossing while both hands can remain comfortably outside of the mouth.
