You already know that brushing at least twice a day and flossing daily are the best ways to keep your teeth and gums healthy. But did you know that chewing gum — sugarless varieties, of course — can help keep your teeth pearly white too? Chewing gum increases saliva production and can break down the bacteria that contribute to tooth decay. If brushing after a midday meal isn’t possible, try chewing gum for 20 minutes instead. Then enjoy the fresh breath that come with it.
