Brushing Your Teeth
Brushing should be done at least twice a day, and may be done after every meal. That being said, after eating or drinking anything acidic, it is important to wait at least an hour before brushing as to avoid damaging the teeth.
How to Keep Your Teeth White
First and foremost, try your best to avoid products that will stain your teeth. This includes coffee, tea, cola and red wine. If you do have to consume these beverages, consider using a straw, so the liquid can bypass your teeth.
If you’re a smoker, stop smoking. Beyond the other health repercussions, smoking is terrible for your teeth, staining them and damaging your gum and bones.
Use a whitening toothpaste. The effects will not be as dramatic as professional whitening, as toothpastes can only target superficial stains, but toothpaste can still help to maintain the whiteness of your teeth. Steer clear of do-it-yourself whitening concoctions, however, and if in doubt, consult your dentist before trying any new products.
Flossing doesn’t need to be done as frequently as brushing, though it is important to floss at least once a day. Right before bed is a great time to do so.
Making sure your gums are healthy is just as important as taking care of your actual teeth. Ideally, your gums should form a tight seal with your teeth that bacteria cannot penetrate.
Physically, your gums should be firm, and not bleed after brushing or flossing. They are typically a light or coral shade of pink, though this can vary slightly based on ethnic origin.
