Practicing good oral hygiene is essential for anyone who wants whiter teeth. Brushing, flossing and using mouthwash are all great ways to take care of your teeth and help prevent stains from forming. Flossing teeth at least once a day can help remove dental plaque that has built up. It is important to wait at least 30 minutes before brushing, after eating and drinking acidic foods. Acids weaken tooth enamel and brushing teeth when enamel is in its weakened state can damage teeth.
The ADA also says that certain foods like apples, pears, celery, carrots, cauliflower and cucumbers can actually help keep teeth cleaner and eliminate bacteria. Adding these foods into your diet can help keep teeth white. Using a straw when you are drinking beverages can help keep stain causing dyes away from teeth. This is especially true for beverages like coffee, tea, wine and sports drinks.
