Supersized brush head for superior cleaning.

The wide oval brush head allows for 3x the bristles of your average toothbrush giving you a cleaning that will improve gum health and leave your teeth feeling tingly and fresh.

Award-winning “easy-grip” design.

That recognizable shape isn’t just for good looks — the Big Brush’s user-friendly handle complies with the dentist-recommended 45-degree brush-to-tooth angle and the smart Thumb-and-Palm design makes it much easier to grip and control.

A sustainable design that works.

From the plant-based, biodegradable cellulose handle sourced from renewable timber to the replaceable head to the vegetable-based nylon bristles, the RADIUS Big Brush is earth-friendly, 100% petroleum free and 100% effective in keeping your smile sparkling.

Never disappointed

I’ve been using Radius for a year now and I totally love it. Not changing back to other type. Best toothbrush ever.

Radius Original Toothbrushes

I have been using Radius Original Right-Hand Toothbrushes for close to twenty years. They are by far the best toothbrushes I’ve ever used. In fact, I refuse to use any other. I love how solidly it feels in my hand and how gentle the brush is on my teeth, gums and tongue. I think that they’re worth every penny of their price.

Radius customer since the 1980's

I've been a Radius customer since the beginning. Always the best cleaning after brushing. I used to get teased for having such a strangely large toothbrush. Most people change their tune when they try it!! I've converted several... don't go away Radius! Don't know what I'll do if thus product leaves one day. Love your reliable customer

Best toothbrush and great service

I bought a 6 pack of this toothbrush because I’m in love with it. I look forward to brushing my teeth because they always feel so clean and I feel like it hit every spot. I gifted this to my dentist and can’t wait to hear what she thinks.
