Nearly 75% of Americans report some level of anxiety about seeing the dentist. Because of their fears, one out of seven will avoid going to the dentist altogether. Yet only about two-thirds of Americans brush their teeth twice a day, as dental health experts have long since recommended for maintaining a healthy smile.

Your smile may be the first thing that people notice about you. But healthy teeth are not only important for looking good. Your oral health can affect your ability to taste and eat, to smell, and to communicate with others.

Do you know what you should and shouldn't do to take care of your teeth at home? What about if your teeth start shifting, or if one is knocked out or chipped?
