What causes tooth decay?
Decay occurs when plaque, the sticky substance that forms on teeth, combines with the sugars and / or starches of the foods that we eat. This combination produces acids that attack tooth enamel. The best way to prevent tooth decay is by brushing twice a day and flossing daily. Eating healthy foods and avoiding snacks and drinks that are high in sugar are also ways to prevent decay.
Four things are necessary for cavities to form — a tooth, bacteria, sugars or other carbohydrates and time. Dental plaque is a thin, sticky, colorless deposit of bacteria that constantly forms on everyone’s teeth. When you eat, the sugars in your food cause the bacteria in plaque to produce acids that attack the tooth enamel. With time and repeated acid attacks, the enamel breaks down and a cavity forms.
