The GUM Summit+ toothbrush has been clinically designed with extremely tapered bristles to help you do the cleaning and plaque removal that your dental professional recommends, so you will enjoy healthy gums and teeth and a clean mouth. The bristles of the GUM Summit+ are truly different. Their extremely fine taper enables a deeper clean between the teeth and beneath the gumline. 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 the gum and the tooth, 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 modern Comfort-Grip handle with wide thumb support provides excellent adaptation to the hand and adds comfort and control while brushing. The unique handle helps positioning the GUM Summit+ toothbrush at the proper 45-degree angle for optimal and easy cleaning in hard-to-reach areas. Dental professionals recommend the use of GUM Summit+ Toothbrush because it has been shown to clean 4 times deeper below the gumline and 6 times better along the gumline compared to toothbrushes with conventional round-ended bristles.*
