Teeth

Teeth are wonderfully splendid bone fragments. They jut up from your lower mandible and down from your upper jawbone like stalagmites and stalactites, respectively. Teeth are covered in a hard, white substance known as enamel. Now enamel is a wonderful substance. It is the second hardest substance known to man, and its second only to diamonds. But the reason enamel is number two is due to the fact that it can be eaten away. Acids damage and eventually destroy the enamel. And the more enamel that gets eaten away, the more your teeth lose the distinction as being "pearly whites". But enamel is just the outside, whats underneath is pretty cool too. The enamel is hard for a reason, and that reason is to provide protection to the sensitive nerve endings that are located on the interior of each tooth. Those nerve endings need a lot of protection, so it's best that you keep your pearly white enamel in the best health possible. And because enamel is so hard, it enables teeth to do what they do best, and that is brutally mutilate every single morsel of food that finds its way through your jaws. Teeth are specially designed to rip, tear, and mash food into smaller portions that are easier for you stomach and digestive system to process. And they are very good at what they do. Teeth are wonderful fragments of bone, protect them with your life, you'll wanna keep the set you have.
