TEETH AND HEALTHY EATING

age 12 or 13, most kids have lost all of their baby teeth and have a full set of permanent teeth. Ancient Egyptians believed that a mixture of onions, spices and incense would cure a toothache. Today, we know that toothaches happen when you don't take care of your teeth.

Unlike your heart or brain, your teeth weren't ready to work from the day you were born. Although babies have the beginnings of their first teeth even before they are born, teeth don't become visible until babies are about 6 to 12 months old.

You bite into an apple and then try to start talking to your friend about yesterday's math homework. Suddenly something feels funny — one of your baby teeth has fallen out! It's been loose forever, and now there it is, right in your hand. And you have an empty space in your mouth big enough to poke a drinking straw through.
