1 After you eat, tiny bits of food are left between your teeth. Bacteria grow on them, forming plaque.  The bacteria digest the carbohydrates (sugars and starches) in food and produce an acid. This acid dissolves the enamel (the hard outer layer of your tooth) and a hole (cavity) is formed.
Cavities are what you get from tooth decay -- damage to the tooth. Tooth decay can affect both the outer coating of a tooth (called enamel) and the inner layer (called dentin).his exposes the roots of your teeth to plaque. And if you eat a lot of sugary or high-carb foods, youâre more likely to get cavities. Older adults sometimes get decay around the edges of fillings. Seniors often have a lot of dental work because they didn't get fluoride or good oral care when they were kids.
