Strong Teeth and Healthy Gums. Invisible bacteria (germs) cover your teeth in a layer called plaque. To remove plaque, brush and floss your teeth. Brush your teeth at least twice a day, and floss daily.

The bacteria in plaque use the sugar and starch in your food to make acids. These acids eat away the enamel surface of your teeth and cause decay. A small spot of decay on a tooth is called a cavity. Your dentist repairs a cavity by filling it to save the tooth from more decay.

Plaque must be removed daily, or it hardens into calculus or tartar. Calculus irritates your gums and leads to gum disease (periodontal disease). Calculus cannot be brushed or flossed away. You must have your teeth cleaned by a dentist or a dental hygienist to remove it. It is good to have your teeth cleaned twice a year by a professional.

Brushing and Flossing. Brush your teeth with a soft brush. Get a new toothbrush when yours is worn or after you have been sick. Never share a toothbrush. Daily flossing removes plaque between teeth.

Nutrition.What you eat affects your teeth and gums. When you eat also affects your teeth and gums. Good nutrition (fruits, vegetables, grains, milk, meat) makes teeth strong and gums healthy. The more sugar and starch your diet contains, the more likely you are to get tooth decay. Sugars and starches between meals are more harmful than sugars and starches with a meal.

Regular Dental Care.Regular visits to a dentist help you keep healthy teeth and gums.
