Our toothbrush head was designed with radiating bristles embedded in a curved bristle bed and connected to a longer neck so that you get a deeper clean and a stimulating gum massage all at the same time. It’s a smaller head than the Big Brush™ and Flex™ Brush but the bristle design means the same gum stimulation and massaging benefits. Choose your bristle type! Our Super Soft Flossing bristles are tapered to get closer to your gum line while our Soft and Medium bristles are end-rounded for a pillow-soft clean.
