Brush your teeth well twice a day. This removes the film of bacteria from the teeth. Be sure to use a soft-bristled toothbrush that is in good condition. Toothpastes and mouth rinses containing fluoride strengthen the teeth and help prevent decay. Choose products that bear the American Dental Association Seal of Acceptance, a symbol of a product's safety and effectiveness. The ADA reviews all advertising claims for any product bearing the Seal. The Seal on a product is an assurance for consumers and dentists against misleading or untrue statements concerning a product and its use, safety and effectiveness.

Clean between your teeth every day. Cleaning between your teeth with floss or interdental cleaners removes bacteria and food particles from between the teeth, where a toothbrush can't reach. Early gum disease can often be reversed by daily brushing and flossing. If you use interdental cleaners, ask your dentist how to use them properly, to avoid injuring your gums.

Eat a balanced diet. Choose a variety of foods from the basic food groups, such as breads, cereals and other grain products; fruits; vegetables; meat, poultry and fish; and dairy products, such as milk, cheese and yogurt. Limit between-meal snacks.

Visit your dentist regularly. It is important to have regular dental checkups, and professional cleaning is essential to prevent periodontal diseases.
