ANNOUNCER: What Lives Inside Your Mouth? Brought to you by the U.S. Department of
Health and Human Services National Institutes of Health. We all know there are living things like trees birds and bugs because we can see them. But some living things are so small that
we can’t see them unless we use a microscope. Some of these tiny creatures are called bacteria. We all have bacteria living in our mouth. They love it there because the inside of our mouth is dark, damp, and warm. Some of the bacteria in your mouth are
good for you but some are not. Some bacteria form gluey stuff on
your teeth called plaque. Many of the foods you eat especially
sugary and starchy foods, cause the bacteria in plaque to produce acids. These asses attack your tooth enamel and after many acid attacks your
teeth decay or get cavities. Is there anything you can do about this problem? Yes, you could buy thirty for the fluoride toothpaste, eat healthy meals, and limit the number of times you snack, and when you do snack, eat healthy foods.
