Colgate Keep is a replaceable head manual toothbrush for 80% less plastic*. Deep Clean with Floss-Tip bristles gently reach 4x deeper below the gum line and between teeth. Plus, our unique tongue and cheek cleaner helps get rid of more bacteria**. Colgate Keep has a long lasting and lightweight aluminum handle with a grip that doesn’t slip for control while brushing. Each starter kit comes with two brush heads so you can easily swap in a fresh new toothbrush replacement head after three months, as recommended by your dentist and hygienist. *Compared to similarly sized Colgate toothbrushes **vs. brushing teeth alone with an ordinary flat-trim toothbrush.
