Feature

Supersized, gum massaging design.

The wide oval brush head is designed to improve gum health and can even reduce the risk of gum and heart disease by massaging the whole mouth — leaving you with that tingly-fresh feeling. It’s like a trip to the dentist, every day and night. Pair these replacement heads with our Big Brush™ or our Source™ Brush.

A longer lasting brush.

These brushes are designed to last longer than the average toothbrush. That means you get a better cleaning and create less waste.

Replacement Head for reduced waste

By using a Replacement Head, 90 out of every 100 toothbrushes escape the fate of the landfills. Your forever handle is made from renewable timber and designed to last. Help us turn the tide on the plastic epidemic that litters our fields and clogs our oceans.

love it

I haven’t had one of these toothbrushes in decades and thought the company no longer existed. The wider head and design really work better.

I love this tooth brush!

I have been using Radius tooth brushes for many years. It is one of the few, if not only, companies that makes a left handed tooth brush. Now with the introduction of the replaceable head (brush section) I like it even more.
