SymplBrush was designed to eliminate the most common cause of dental decay, injury, and gum disease; user error. By harnessing the equivalent of twenty toothbrushes working simultaneously, SymplBrush delivers a safe, clinically proven, effective clean each and every time you use it. Our patented "Living Hinge" bristle design allows SymplBrush to be the first effective, safe full-arch toothbrush as proven by the Forsyth Institute, an affiliate of The Harvard Dental School in Cambridge, Massachusetts.
