What people are saying.
I always liked Radius tooth brushes. Now I like that I can keep my handle and change my brush out. Great hygienic care for my oral care regime. Awesome innovations for a healthy environment for the customer!
Better brush that covers more teeth while brushing.
Best toothbrush ever
My husband is super picky in general but especially about his toothbrushes (his father was a dentist!). We discovered Radius toothbrushes years ago and have been faithful to the brand because it’s simply the best out there. The new Big Brush with the Replaceable heads is our favorite because it’s so comfortable to hold and the replaceable heads are a great idea.
I really love the big brush with replaceable head it works great ! Ever since i started using Matcha mint toothpaste my gums are so healthy. And now i have the big brush to brush my teeth and gums are even so much better. My teeth feel strong and my gums feel great. I truly believe everyone should get an big brush with replaceable head or the source brush to help our beautiful planet. We can do our part to change the environment to make it healthy again. That's why i chose radius is because i love our planet earth. I know when i brush my teeth i keep my heart healthy and pray that the heart of nature is healthy too. Thank you radius 😘
