Yes, though we do recommend using your new RADIUS toothbrush for a whole week before deciding if you don't like it. The bigger head can take some getting used to!
The Big Brush™ features a wide oval head designed to improve gum health and massage your whole mouth. If our Big Brush™ still feels too large after trying for a week, the Source™ Toothbrush is a great alternative. It has a smaller head, a slim, longer neck for reaching tight spaces, and does not have the 45-degree angle.
The Source™ head is about 50% smaller than the Big Brush™ and Flex™ Brush but still contains 200–300% more bristles than an ordinary toothbrush. All of our replacement heads are interchangeable, so you can use Big Brush Replacement Heads with the Source handle and vice versa.
