The SDC Power Brush and Floss System is the perfect electric toothbrush for the whole family; it adapts to many difficult brushing situations like a misplaced tooth, a metal bracket for a bridge, or orthodontic braces by retracting certain bristles, so surrounding bristles can maintain perfect contact with the surface or obstruction. The secret is a high-tech innovation that organizes thousands of bristles into 16 discrete bundles; each bundle is mounted on a retractable spring lodged in the base of the brush head.
