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.

BIG BRUSH FOREVER!

I have been using the Radius Big Brush since it first came out. No toothbrush even comes close to making such a huge foam out of a tiny blob of toothpaste. It cleans teeth and gums at the same time and makes your breath so fresh. The Big Brush is “da bomb”!! 😊

I have bought these for many years and they are the only toothbrushes that I like..I was very disappointed to find out that you were discontinuing them. I am glad that you were able to find apparently the last few back in the warehouse..If you can find 10 or so more, I would like to have them too.

Have had great dental check-ups ever since I discovered this brush years ago. Too bad the big brush in this configuration is being discontinued. Bought every one I could get at this time. So useful, even when it's "used up."
