What causes cavities?

Many factors play a role in the development of cavities. These steps typically occur:

• Bacteria in the mouth feed on sugary, starchy foods and drinks (fruit, candy, bread, cereal, sodas, juice and milk). The bacteria convert these carbohydrates into acids.
• Bacteria, acid, food and saliva mix to form plaque. This sticky substance coats the teeth.
• Without proper brushing and flossing, acids in plaque dissolve tooth enamel, creating cavities, or holes.
