Smart and Sustainable
I’ve been using the RADIUS Source™ for a while now, and it’s easily one of the most comfortable brushes I’ve tried. The wide head covers more surface, and the soft bristles feel gentle but clean really well. The handle is ergonomic and made from recycled materials, which I love. Plus, you can just replace the head instead of tossing the whole thing smart and sustainable.

The Big Brush proves that a sustainable toothbrush doesn’t have to compromise on deep-cleaning power. The head is replaceable, so you can reuse the handle for years, making this one of the most eco-friendly brush options on the market.
With its replaceable head system, the RADIUS Big Brush toothbrush is 93% less wasteful than your average toothbrush. Each handle is made from renewable timber and enhanced with EcoPure, an organic additive that helps it biodegrade, even in landfill and marine environments. BPA and PFAS-free for you and the planet.

Frequently Asked Questions
Answers to common questions to help you understand things better.
How often should I replace the head?
Every 3-6 months or when bristles show wear. Just pop off the old head and click on a new one. A RADIUS replacement head toothbrush can last up to 3x longer than other brands, but the life of your toothbrush depends on how hard you brush and how often.
Are the bristles soft?
Yes. The Source™ comes in Super Soft Flossing, Soft, and Medium bristle types. 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. Our wide heads have over 3000 plant based bristles to help cover more surface area, protect enamel, and improve gum health all in one deep cleaning toothbrush.
Is the RADIUS Source™ Toothbrush biodegradable?
Each RADIUS Source™ Toothbrush is a biodegradable toothbrush made from renewable, recycled materials and plant based components, sustainable by design. In addition, all RADIUS toothbrushes contain EcoPure®, an organic additive that helps products biodegrade more quickly in landfills. A material without EcoPure degrades at a rate of 3.2%, but a material with EcoPure degrades at a rate of 40.2%. That’s a significant change!
Where is the RADIUS Source™ Toothbrush made?
Every Source™ Brush is crafted in the USA at our Pennsylvania facility using low-energy machines, a commitment to sustainability from handle to bristle.
