Did you know that a scientific study has shown that chewing Big Red Gum reduces mouth microbes? (ScienceDaily contributors, 2004) The cinnamon oil in the gum is a natural defense against mouth bacteria that cause tooth decay and bad breath. Conduct an experiment to compare products with cinnamon essence in gum, candy, toothpaste, and mouthwash to see if they can decrease mouth germs. Do a before and after swab of the mouth with a Q-tip. Which treatments work the best? Can you find another useful ingredient in other natural oils or essences? What about peppermint, wintergreen, or spearmint?

Career Profile
Good oral hygiene protects not only teeth and gums, but the whole body, reducing the risk of infections, heart disease, clogged arteries, and stroke. Dental hygienists help prevent and correct dental problems by taking X-rays, examining teeth and gums, removing plaque, polishing teeth, injecting local anesthetics, and assisting with dental procedures. They also play a key role in educating patients about how and when to brush and floss. Read more
Career Profile
Microorganisms (bacteria, viruses, algae, and fungi) are the most common life-forms on Earth. They help us digest nutrients; make foods like yogurt, bread, and olives; and create antibiotics. Some microbes also cause diseases. Microbiologists study the growth, structure, development, and general characteristics of microorganisms to promote health, industry, and a basic understanding of cellular functions. Read more
