The Colgate 360 Advanced Floss-Tip Bristles manual toothbrush is designed with tapered bristles that are 17 times thinner than ordinary end-rounded bristles. The purple-ended tapered soft bristles gently reach deep between teeth and along the gumline for a 4X deeper reach, compared to an ordinary flat trim toothbrush. The toothbrushs unique cheek and tongue cleaner removes odor causing bacteria better than brushing teeth alone with an ordinary flat-trim toothbrush. The raised tip helps gently clean hard-to-reach areas of the mouth. This toothbrush does not replace flossing.
