Egg shells and teeth have something in common! Both can be weakened by acid! When you put an egg in vinegar (a weak acid similar to what causes cavities), it attacks the shell (enamel), making it soft and weak. When teeth are exposed to acids in your mouth, your teeth become vulnerable to cavities. This experiment shows you how you can help LOCK IN the calcium in an egg shell (your teeth) by protecting them with a fluoride toothpaste!
