What causes cavities?
Your mouth is a busy place. Think of it as Grand Central Station... With teeth. Instead of commuters, Bacteria - tiny colonies of living organisms are constantly on the move on your teeth, gums, lips, and tongue. Having bacteria in your mouth is a normal thing. While some of the bacteria can be harmful, most are not, and some are even quite helpful.
Certain types of bacteria can attach themselves to hard surfaces like the enamel that covers your teeth. If the bacteria is not removed, it multiplies and grows until a colony forms. More bacteria of different types attach to the colony already growing on the tooth enamel. Proteins that are present in your saliva also mix in with the bacteria colony and become a whitish film on the tooth. This film is called plaque, and it is what causes cavities. Brushing and flossing after EVERY meal is the only way to prevent this.
How does Plaque cause cavities?
The hard, outer covering of your teeth is called enamel. Enamel is very hard, mainly because it contains durable mineral salts, like calcium. Mineral salts in your saliva help add to the hardness of your teeth. Mineral salts, however, are prone to attack by acids. Acid causes them to breakdown.
The plaque that forms on your teeth and doesn't get washed away by saliva or brushed away by your toothbrush, produces acid as it eats up sugar. This acid is produced inside the plaque and can't be easily washed away by your saliva. The acid dissolves the minerals that make your tooth enamel hard. The surface of the enamel becomes porous - tiny holes appear. After a while, the acid causes the tiny holes in the enamel to get bigger until one large hole appears. This is a cavity. It's important to see your dentist before a cavity forms so that the plaque you can't reach with your toothbrush or floss can be removed.
