RADIUS® Source™ Brush – Eco-Friendly Toothbrush with Replaceable Head Medium

A toothbrush designed for a cleaner smile and a cleaner planet. The RADIUS® Source™ Brush combines a replaceable head with an upcycled handle, reducing plastic waste by an impressive 93%. Instead of tossing out the whole toothbrush, simply swap the head and keep brushing. Small change, big impact.

The medium-sized head features vegetable-based nylon bristles, radiating from a curved bristle bed for a deeper clean. The design doesn’t just polish teeth—it gently massages gums while reaching tricky spots with ease. Paired with a long, slim neck and an ergonomic handle made from repurposed materials, this sustainable toothbrush is built for comfort, control, and lasting performance.
