The Big Brush™/Flex™ Brush is too big for my mouth.

The wide oval brush head of the Big Brush™ is designed to improve gum health and can even reduce the risk of gum and heart disease by massaging the whole mouth. If our Big Brush™ is too big for you, we suggest you try our Source™ Toothbrush. It features a much smaller head and does not feature the 45-degree angle. The Source has a slim neck that’s longer than your average toothbrush to provide maximum reach in tight spaces.
