Brush at least twice a day. If you can, brush after every meal. Ideally wait 30 minutes after eating, this will allow any enamel that softened from acid during eating to re-harden and not get brushed away. Brushing removes plaque, a film of bacteria that clings to teeth. When bacteria in plaque come into contact with food, they produce acids. These acids lead to cavities.
• Place a pea-sized dab of fluoride toothpaste on the head of the toothbrush. (Use a soft toothbrush.)
• Place the toothbrush against the teeth at a 45-degree angle up to the gum line.
• Move the brush across the teeth using a small circular motion. Continue with this motion cleaning one tooth at a time. Keep the tips of the bristles against the gum line. Avoid pressing so hard that the bristles lie flat against the teeth. (Only the tips of the toothbrush clean the teeth.) Let the bristles reach into spaces between teeth.
• Brush across the top of the chewing surfaces of the teeth. Make sure the bristles get into the grooves and crevices.
• Use the same small circular motion to clean the backside of the upper and lower teeth — the side that faces the tongue.
• To clean the inside of the bottom front teeth, angle the head in an up-and-down position toward the bottom inside of the mouth and move the toothbrush in a small circle.
• For the inside of the top front teeth, angle the brush in an up-and-down position with the tip of the head pointing towards the roof of the mouth . Move the toothbrush in a small circle.
• Give your tongue a few gentle brush strokes, brushing from the back of your tongue forward. Do not scrub. This helps remove bacteria and freshens your breath.
• After brushing your teeth for two to three minutes, rinse your mouth with water.
• Replace your toothbrush with a new one every three to four months.
