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. The replacement head toothbrush is designed to easily remove and snap into place, no twisting required

Is the RADIUS Big Brush biodegradable?

Yes. Each RADIUS Big Brush is a biodegradable toothbrush made from renewable timber and 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!

Are the bristles soft?

Yes. The soft, plant-based bristles are end-rounded for a gentle yet effective clean.

Is the RADIUS Big Brush good for sensitive gums?

Absolutely. Its large head distributes pressure evenly to gently massage your gums, helping to prevent recession and bleeding.

Where is the RADIUS Big Brush made?

Every Big Brush is crafted in the USA at our Pennsylvania facility using low-energy machines, a commitment to sustainability from handle to bristle
