RADIUS built the Source toothbrush around a simple idea: replace the head, keep the handle. Because only the compact head needs replacing every few months, the brush cuts waste dramatically compared to tossing a whole toothbrush.
The soft-bristle head is ADA Accepted and made in the USA, with a wide brush design meant to clean gently along teeth and gums.
It's a small swap for anyone looking to trim bathroom plastic waste without changing their brushing routine.
