Invented, designed and engineered in the U.S. -- the 30 Second Smile is recommended by dentists to keep their patients’ teeth as shiny-white as the day they are cleaned, and for reversing gingivitis in a guaranteed two weeks! Six micro-brush heads surround each tooth with soft bristles, cleaning top, bottom, front, back and chewing surfaces -- all at the same time. Brushing only 30 seconds with The 30 Second Smile does more good than brushing three minutes with a single-headed toothbrush. This revolutionary device uses new technology to brush your teeth perfectly every time. You will never want to use an ordinary toothbrush again.
