Clean eating is very trendy these days, but it’s actually been around for generations. Simple raw vegetables like cucumbers or celery require a lot of munching that produces bacteria-buffering saliva that protects your teeth and gums. As well, any naturally fibrous food can help remove plaque and massage your gums. Celery has an additional bonus; its leaves are a great substitute for breath- freshening parsley. Simply snack on a handful of your favorite raw vegetable for a great tasting salad.
