Globally, cavities are a widespread concern. They are decayed areas of the teeth that have become small holes, due to a lack of good oral hygiene. The small holes are a result of the gradual breakdown of the tooth enamel during the gradual process of decay.

Cavities, which are tiny holes in the teeth, can happen at any age. Listen as Dr. Maria Lopez Howell explains why brushing your teeth twice a day and flossing can help prevent tooth decay.

Cavities are holes in the teeth. They are caused by plaque in your mouth. Plaque is bacteria that use the sugars in food that you eat to produce acid. The acid eats into the tooth causing a cavity. Proper brushing, a diet low in sugars, and regular visits to the dentist can help prevent cavities.
Cavities are small holes that slowly develop in the teeth because of tooth decay.
Tooth decay usually happens slowly over a period of months or years. Acids made by plaque eat away at the hard (mineral) part of the tooth. Sometimes the tooth can use minerals in saliva to rebuild itself. A cavity forms when the damage caused by acids is more than the tooth can repair.
Mild tooth decay may be helped by effective tooth-brushing and flossing, as well as daily rinsing with fluoride mouth care products. More serious tooth decay that has caused cavities may require fillings to stop the decay and prevent further damage to the teeth.
Infants who are put to bed with a bottle or who are allowed to suck on a bottle with any sugar-containing substance (such as juice) for a long time may develop cavities, especially in the upper front teeth. This condition is called "baby bottle tooth decay." Children who have cavities in several teeth (usually the upper front teeth) may have trouble chewing hard foods and learning to speak, due to pain and tooth damage. Cavities in infants can often be prevented by making sure the baby's mouth and teeth are cleaned after the last feeding at night.

Cavities, otherwise known as dental decay or dental caries, are holes in the teeth caused by demineralization of the enamel of the teeth. The demineralization process starts on the outside of the tooth by acids produced by bacteria. A thin film of biomaterial called plaque forms on the surface of the tooth. Acid producing bacteria live in the plaque. These bacteria utilize sugars like sucrose, glucose and fructose as their food sources. The waste products of the bacteria are acids, particularly lactic acid, that cause holes in the enamel and dentin of the teeth.
