Healthy teeth are clean and have no cavities. Healthy gums are pink and firm, and do not bleed. To maintain healthy teeth and gums, follow these steps:

• Floss at least once per day. It is best to floss after brushing. Flossing removes plaque that is left behind after brushing from between the teeth and on the gums.
• Brush your teeth twice a day with a soft-bristled toothbrush. Brush for at least 2 minutes each time.
• Use fluoride toothpaste. The fluoride helps strengthen tooth enamel and helps prevent tooth decay.
• Replace your toothbrush every 3 to 4 months or sooner if needed. A worn-out toothbrush will not clean your teeth as well. If you use an electric toothbrush, change heads every 3 to 4 months as well.
• Eat a healthy diet. You are less likely to get gum disease if you eat healthy foods.
• Avoid sweets and sweetened drinks. Eating and drinking a lot of sweets increases your risk of cavities. If you do eat or drink sweets, brush your teeth soon after.
• Do not smoke. Smokers have more teeth and gum problems than non-smokers.
• Keep dentures, retainers, and other appliances clean. This includes brushing them regularly. You may also need to soak them in a cleansing solution.
• Schedule regular checkups with your dentist. Many dentists recommend having the teeth professionally cleaned every 6 months for optimal oral health. Seeing the dentist every 3 to 4 months may be needed if your gums become unhealthy.
