Don't judge a book by its cover or a toothbrush by its head. The Radius Toothbrush might be a bit funny looking, but it is by far the best toothbrush I have ever owned! It is so comfortable but also effective. The soft bristles gently rid my teeth of tartar that collects so easily. I have a problem with my saliva being too rich in calcium, so tartar becomes plaque quickly. But not with the Radius! It effectively cleans my teeth and gums, leaving them feeling totally fresh and smooth. There's no residual gritty feel that some toothbrushes leave behind. Like the name, it offers an allover clean that is deep and wide, as it is able to cover the entire surface of each tooth. Another big bonus: this toothbrush is durable and lasts forever. Not literally, but so much longer than most toothbrushes on the market. My husband is really hard on toothbrushes, and only this one can withstand him! A stronger toothbrush means that you have to replace it less often (as long as you keep it clean, of course)! This translates into benefits for your wallet as well as the environment.
