tooth decay
Definition
Tooth decay is a disease that causes the breakdown of tooth enamel. Enamel is the hard outer layer of the tooth that protects it from decay.
Tooth decay is caused by bacteria that live in the mouth. These bacteria feed on sugar and other food particles, and they produce acids as a waste product. These acids attack the tooth enamel, causing it to break down.
Tooth decay can cause pain, sensitivity, and even tooth loss. It is important to brush your teeth twice a day and floss once a day to prevent tooth decay.
