Answers:

1. FALSE. It’s a common myth that a dog’s mouth is cleaner than a human’s, but animal mouths are also filled with tons of bad bacteria. The catch is that pet saliva is healthier for you than human saliva, because most of the bacteria in your pet’s mouth won’t cause much damage if they’re transferred to you.
2. A. It may seem that covering your brush will block out bacteria, but microbes thrive in moist, enclosed environments. Keep your toothbrush open to natural air to kill any bacteria living on it.
3. C. Keeping your mouth clean will decrease your risk of oral infections. While hand sanitizer can kill the bacteria on your hands before you put them in your mouth, brushing and flossing thoroughly and daily is the safest method.
4. D. You can’t see them, but germs are still there. Throughout the day, you come in contact with money and tables that other people have probably touched before you. The bacteria living on these surfaces will crawl onto your hands, and therefore likely into your mouth and body.
5. B. Tooth stains are caused by dark-colored foods and beverages and poor dental care. They are not contagious. On the other hand, tooth decay and cold sores can be passed from another person.
6. FALSE. As soon as food hits the floor, it becomes contaminated with germs and bacteria.
