What people are saying.
Love our new toothbrushes! So easy to use!
The big brush is unlike anything else for keeping my mouth super clean and conditioning my teeth and gums. I love it, and the replaceable head is a bonus.
Big Brush with Replaceable Head
I mainly bought the brush for the green reasons but after my first time using it having a bigger surface makes it easier to get every spot!
I’ve been using Radius toothbrushes for 1 1/2 years. Absolutely the best toothbrushes ever. I prefer the small head, but my husband likes the big head. When my first toothbrush arrived, I thought it might be too soft, I used it anyway, and fell in love. I also love that I can just change out the brush and not contribute to excess trash.
