What people are saying.
I absolutely love this toothbrush! The bristles are soft and plentiful, giving you an amazing clean, polished feeling. You also stimulate your gums while brushing with the Big Brush. This is an amazing toothbrush!
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.
