  • Publication number: 20090007930
    Abstract: A dental flossing device that aids proper oral hygiene between teeth without exerting manual forces. The accordion-like structure of the head unit attaches a floss filament bow of fixed dimension which then attaches to a handle. The unique head unit of the device facilitates the passing of the flossing filament through the contact areas between teeth utilizing biting forces than those of the hands and arms. Accordingly, this eliminates the need to require manual dexterity and exertion while flossing. The retractable head unit can be fabricated using a spring-like mechanism which allows it to collapse and return to its original shape or it may be automated using electrical power.
