The GUM Technique Deep Clean toothbrush has been clinically designed to help you do the cleaning and plaque removal your dental professional recommends so you will enjoy healthy gums and teeth and a great clean-feeling mouth. The Quad-Grip handle has a unique design that helps you always hold the brush the way most dental professionals do-at 45 degrees. Whether you are left- or right-handed, brushing upper or lower teeth, the handle intuitively helps you form the 45-degree angle that is more effective at cleaning away the dental plaque from both gums and teeth. This makes sure you have the right dental "technique." The bristles of the GUM Technique Deep Clean toothbrush are truly different. Their extremely fine taper enables the "deep clean." The very fine tapered bristle ends are narrower and more flexible than any other bristle design so they can reach deep into the crevices between gums and teeth, as well as farther between the teeth, to remove the disease-causing germs that other brushes leave behind. A bi-level, second layer of bristles in the center of the brush cleans the exposed tooth surfaces. The GUM Technique Deep Clean is no ordinary toothbrush-it is designed to give you that extra edge in the daily battle with dental plaque so your own and your family's oral health can be everything that you and your dentist want it to be.
