The Radius Source toothbrush gives you a lot to smile about. Along with a replaceable head that allows you to discard only the part of a toothbrush that wears out, each handle is made from renewable plant sources like corn, trees and wood fiber. Those are great environmental benefits. But that's not all. It's the first toothbrush of its kind to have radial bristling that makes brushing easier and more effective, and bristles that are reversible for right or left handed users. This all adds up to quite a remarkable toothbrush that could make a marked improvement in the environment and your dental hygiene
