Spry Mints not only freshen your breath, but they also defend against dental health problems. Each mint has .5g of xylitol—a natural sweetener. Xylitol also doesn’t allow bacteria to stick to teeth. This quality means the bacteria can’t colonize in the mouth. Because they can’t thrive, they also can’t produce their bi-product, acid, which is the culprit to tooth decay and cavities.
