Article in English: . This is the most important step, so don't skip it. Teeth should be brushed three times a day, after each meal.  Be sure to brush the full surface area of your teeth accessible with your toothbrush; this includes the cheek side, the tongue side, and the chewing surface of your teeth.   Angle the toothbrush 45 degrees where your teeth meet your gums, and gently massage the toothbrush over this area to ensure it is cleaned as well. Do not press too hard here as it can be damaging.   Brush your teeth for two minutes. This helps to clear away plaque and bacteria, and to keep your teeth clean and shiny. Flossing should be done at least once a day.  Flossing cleans an additional 33% of tooth surface area that cannot be reached with a toothbrush alone.   Flossing also removes plaque before it hardens into tartar, which keeps your teeth looking cleaner and healthier.   For optimum flossing, take a piece of floss about 12 inches long and wrap it around your index finger on each hand, leaving at least 2 inches in between. Slide it between each of your teeth, being sure to go from the top of the tooth all the way to the base. Repeat two to three times to ensure plaque is removed. This can help to keep your mouth and teeth clean. Some mouthwashes have additional "whitening" properties, but it depends on which brand you buy - read the product label for more information. This is critical in maintaining good oral hygiene, and your dentist can provide you with additional information and suggestions specific to you.
