Tooth decay and cavities are among the world’s most common oral health problems. These problems are most often seen in children, teenagers and older adults. However, anyone can get cavities.

Dental cavities, also referred to as caries, are holes in the teeth caused by tooth decay. Decay usually occurs due to a bacterial infection that causes demineralization and destruction of the hard tissues in the teeth.

Certain factors can increase the risk of getting cavities, including foods that cling to your teeth for a long time, frequent snacking or sipping, poor oral hygiene, not getting enough fluoride, dry mouth, worn fillings or dental devices. Eating disorders like anorexia and bulimia can also contribute to serious dental problems due to repeated purging.
