Tired of tossing your toothbrush into the trash? Switch to a Radius Source Toothbrush and you’ll cut way back on plastic usage and waste. The handle of this soft-bristled toothbrush is composed of recycled materials, while the gum-massaging heads are replaceable. 

What else makes the Radius Source Toothbrush so unique?

The Source’s curved bristle-bed is made to stimulate, not aggravate, the gums and teeth for optimal oral hygiene. Plus, this ergonomic handle is easy to maneuver for right-handed brushers as well as lefties.

The handle is composed of repurposed and recycled materials — like wood, paper and even recycled dollar bills, dye-free bristles made from vegetable-based nylon.

As user-friendly for lefties as it is for right-handed brushers, the ergonomic handle design helps reduce pressure on teeth and gums for optimal oral health. Find refills here.
