Feature

Gum massaging bristles.

The unique curved bristle-bed ensures our plush bristles clean and massage the gum rather than aggravating them. Choose your bristle type! Our Super Soft Flossing bristles are tapered to get closer to your gum line while our Soft and Medium bristles are end-rounded for a pillow-soft clean. Pair these replacement heads with our Big Brush™, Source™ Brush, or TOUR™ Travel Brush.

Longer neck for better reach.

A long, thin neck makes cleaning tricky-to-reach spots much easier — all the way to the very last molar.

Premium, eco-friendly bristles.

The soft bristles are made from vegetable-based nylon to reduce our dependence on fossil fuels. The bristles are arranged in an elegant fanned shape, designed to gently yet thoroughly clean and invigorate the entire mouth.

great handle

The handle on this brush is ideal for those with arthritis, very comfortable, and of course the brush head is also so comfortable. I appreciate being able to simply replace the head and reduce my plastic use!

I keep getting the wrong Replacement Heads and I don't know how to stop them

Per my dentist, I'm seeking the floss/very soft model - and I can't figure out how to change this... to get the right ones.

Very Well Designed and Made Product!

Saw an online ad for Radius and was curious, so I purchased a toothbrush and several replacement heads for myself. Everything was well packaged and this is the best (manual) toothbrush I've ever used. I may need to try out some toothpaste next time!
