Radius Source Toothbrush

The toothbrush features a solar panel integrated into the handle that converts ambient light—whether from sunlight or indoor lighting—into the energy needed to power the cleaning action. You do not need to leave it in direct sunlight; standard bathroom lighting is sufficient to keep it charged for daily use.

Yes, the toothbrush is designed with a simple, replaceable head system. Each unit comes with two replacement heads, and you can purchase additional heads directly from the manufacturer to minimize plastic waste compared to disposing of the entire brush.

The wide bristle design is specifically engineered to massage the gums and reduce issues like chronic bleeding and enamel erosion. While the bristles are medium-firm, the broad surface area helps distribute pressure more evenly across your gum line, which can be gentler than traditional, narrow-bristled brushes.

No setup is required. The timer is built into the brush to automatically track your brushing session, ensuring you hit the dentist-recommended two-minute mark every time you use it.

The handle is designed with a universal, ergonomic shape that accommodates a wide range of hand sizes. Its balanced weight and grip profile are intended to provide a secure, comfortable hold regardless of your hand size.
