Colgate 360 Total 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 bristles gently reach deep between teeth and along the gum line for a 4X deeper reach, compared to an ordinary flat trim toothbrush. Our unique cheek and tongue cleaner removes bacteria better than brushing teeth alone with an ordinary flat-trim toothbrush. This toothbrush does not replace flossing. Size: 1ct. Gender: unisex. Age Group: adult.
