Your Body Battles a Cavity PDF

If you want to hear a scary sound, you don't even have to go to a horror show. The only thing you'll need to do is forget about taking care of your teeth, get a few cavities that need filling and you can listen to the dentist's drill. Bzzz bzzz bzzz bzzz! A toothache is a miserable thing to have, but you don't have to have them if you take good care of your teeth. In this book you'll meet five superheroes, the red blood cell, the salivary gland cell, the neutrophil, the odontoblast and the nerve cell, all of which can help you to "keep your teeth healthy."

You have different kinds of cells in your body and when you get a toothache there are germs that are attacking come of them. Your tooth is made up of enamel, pulp and dentin. When you get a cavity eventually you may get a toothache because if you neglect it the cavity can eat through the enamel and the dentin right down into the pulp. Your nerve cells will "send a message to your brain" that let you know fairly quickly that there is something wrong. In this book you'll learn all about how you can prevent cavities by making sure that bacteria called Streptococcus mutans (these cause plaque) stay out of your mouth, how to brush properly and what causes this bacteria to do its nasty deed on your teeth.

You'll learn about odontoblasts and how they "help keep dentin strong," how nerve cells can signal to you that you have something amiss, how red and white blood cells (neutrophils) fight infections and how your salivary glands produce saliva to wash your teeth. You'll also see some very interesting photomicrographs that "were taken with a scanning electron microscope (SEM) that will absolutely amaze you!
