How can I tell if I'm brushing and flossing properly?
Brushing: Brush your teeth gently, paying special attention to the areas where your teeth and gums meet. Clean every surface of every tooth. Use the tip of your brush to clean behind your upper and lower front teeth.
Flossing: Take a piece of floss about 18 inches long and wrap it around your middle fingers. Using a clean section of floss each time, wrap the floss into a C shape around a tooth. Wipe it over the tooth, from base to tip, a couple of times. Repeat on each tooth.
