Plaque is a type of buildup that occurs throughout the body, and no matter where it accumulates it is dangerous to your health. Dental plaque is a soft, white, sticky film that develops on the teeth each day. Millions of bacteria live inside the mouth on any given day, and they react to the foods and beverages that you consume. After every meal, snack, piece of candy, soft drink, cup of coffee, glass of wine – anything other than water – the bacteria create a constant assault on your teeth.
