When I was 50 I discovered the Radius toothbrush (original) in an Albertson's grocery store. The moment I saw it, it made good sense to me. Why brush with only a small number of bristles, when you can brush with a bunch and accomplish so much more! I tried it, loved it and have used one ever since. I am now 70 and my dental hygienist is very pleased with my oral health. I began giving these toothbrushes to my kids at Christmas. They love them, too, and now my grandchildren as well. So for the past several years, I have made use of the online sales and I buy the 6 packs for Christmas giving….and when they come to visit from out of state. The hardest thing about the 6 pack is deciding who gets which color. Thanks so much for making a sensible product, and for having the sales so I can stock up for my family.
The Radius is my new tooth brushfor life!

The only thing I would change is to add the option of a line of medium bristles down the middle of the brush head. Only about 25% of the bristles being medium strength, and not at the outer edge.
Happy Smile !

I just started to use the Original Radius. After brushing, my gums feel wonderful,like they've had a gentle massage, my teeth are sparkling clean...This will be my toothbrush from now on! Thank you for inventing and producing this. And very happy it's made here in the US!

I'm 16, and my dentist was actually shocked I don't have cavities. Sense I don't floss and eat plunty of junk. But I swear it is because of this tooth brush! It covers my whole mouse. Sense I started using it; old regular brushes feel awkward and weird. I highly suggest this tooth brush. Plus it's lasted me so long till I need a replacement.
