More bristles, more surface area, better cleaning.

With 3x the normal toothbrush’s bristles, the wide oval brush head coupled with a flexible neck helps target those tricky-to-reach areas and massages the whole mouth as it goes for an all-over tingly clean, that lasts 3x longer than other run-of-the-mill toothbrushes.

“Flex-Neck” Technology meets award winning easy-grip design.

The design of the Big Brush with a twist, made from flexible recycled rubber with a soft head stems, the angled neck reduces pressure on gums and teeth — especially if you’re a hard brusher.

Created to keep your teeth and the world clean.

From the recycled rubber handle to the vegetable-based nylon bristles, the RADIUS Flex Brush is eco-friendly from top to bottom.

Thirty years and counting

I’ve been using a radius toothbrush for over 30 years now and would be lost without it. I love how it brushes my whole mouth and my dentist is always amazed that I never have plaque. I’m 65 and my gums are still healthy…I would never switch to a different product at this point. If something ever happened to this company, I’d try to buy a lifetime supply first.

Never disappointed

I’m always very pleased with all things Radius. I’ve been using the Radius brand Scuba toothbrush for years and wouldn’t think of changing brands or style. Thank you, Radius for helping me maintain healthy teeth and gums!
