The Original has such a large head because it’s not your ordinary toothbrush…it’s an entire MOUTHBRUSH! The wide massaging head helps reduce chronic bleeding and receding gums. When you brush your teeth, you want to include your gums as well and the Original makes sure that you’re reaching your entire mouth.
There are 300% more bristles than competitors and they have a non-aligned layout to avoid tooth erosion. The Original has soft, premium bristles that are spread evenly over the large head for even applied pressure. You won’t be neglecting any teeth with the Original!
