Cavity Book

Oh, no! You've got a cavity. Your teeth are the hardest things in your body, yet tiny germs are able to make holes in them. A hole in your tooth is called a cavity, and once you have one, only a dentist can come to the rescue. The key is to prevent cavities from forming in the first place. Every day, there's a battle going on in your mouth. Acids and bacteria attack your teeth and plaque builds up. Your body has superheroes—your saliva—that try to fight off acids. By brushing and flossing your teeth, you can help your body fight off the germ invaders and prevent cavities. Get a close look at the battle going on in your mouth with comic illustrations and ground-breaking photomicrographs. The photomicrographs magnify the actual cellular processes thousands of times, offering you a front-row seat for all the action.
