Have you ever wondered what the plaque on your teeth actually is? Dental plaque, also known as tooth plaque, microbial plaque and dental biofilm, is a soft, sticky film that builds up on your teeth. Plaque is an extremely sticky, colorless to pale yellow deposit of biofilm that regularly forms on your teeth. When saliva, food, and fluids combine they produce bacteria deposits, which collect where the teeth and gums meet. Plaque contains bacteria, which produce acids that attack your tooth enamel and can damage your gums. If not treated, the damage could become permanent. It contains millions of bacteria that feed on the food and drinks you eat every day. If bacteria deposits from plaque on teeth aren’t removed through regular brushing and flossing, they can cause tooth decay, gum disease, and tartar buildup.
