Xylitol, the sweetener used in Rivo Mints, is a safe natural sweetener without the bad side-effects of sugar and artificial substitutes and is also also good for your teeth! It does not break down like sugar and can help keep a neutral pH level in the mouth. Xylitol prevents bacteria from sticking to the teeth - which is how it protects the teeth from tooth decay. With the dental benefits of Xylitol, the acid attack that would otherwise last for over half an hour is stopped. Be sure to eat Rivo Mints for a healthy smile!
