Startup Idea : Cereal or Breakfast That Cleans Your Teeth

Have you ever been lazy to brush your teeth after breakfast, or were just in a rush to get out to go to work? What if there were a cereal that actually tasted great, was healthy, and cleaned your teeth at the same time? This would be a non-alcoholic cereal, yet it would essentially have something in it that would do the cleaning for you, so that you can be confident about your breakfast, and feel good about brushing later because the cereal would have something good in it that cleaned your teeth.
