This toothbrush, with a remarkably smooth surface, has a built-in toothpaste container in its handle with sufficient toothpaste for a month of daily brushing. At the touch of a button, the paste is fed through internal channels to the brush head. Silicone valves prevent the toothpaste from drying out or leaking. The brush can be easily rinsed out from the inside between refills. Its two main components are made of food-grade plastic and overmoulded with soft, hypoallergenic silicone.
