When to brush your teeth
When should you brush your teeth? Learn how to protect your oral health.
Want whiter teeth?
If your pearly whites are dulled by surface stains, whitening toothpaste can appear to whiten teeth slightly. Whitening toothpaste can't change the natural color of your teeth, however. For more noticeable results, ask your dentist about tooth-whitening bleaching products.
Toothpicks: For hors d'oeuvres, not teeth
Have something stuck in your teeth? Use a toothbrush, dental floss, or an interdental cleaner — such as a dental pick, pre-threaded flosser, tiny brushes that reach between teeth, a water flosser, or wooden or silicone wedge plaque remover. Save toothpicks for olives. If you use a toothpick to clean your teeth, you could injure your gums and let in bacteria.

Does flossing really make a difference?
Yes. You can't reach the bacteria in tight spaces between your teeth and under the gum line with a toothbrush. Aim to floss daily. If you find it hard to handle floss, use an interdental cleaner — such as a dental pick, pre-threaded flosser, tiny brushes that reach between teeth, a water flosser, or wooden or silicone wedge plaque remover. As long as you do a thorough job, it doesn't matter if you brush or floss first.
