Introduction

Cavities are decayed areas of your teeth that develop into tiny openings or holes. Cavities, also called tooth decay, are caused by a combination of factors, including not cleaning your teeth well, frequent snacking and sipping sugary drinks.

Cavities and tooth decay are one of the most common health problems around the world. They're especially common in children and young adults. But anyone who has teeth can get cavities, including infants and older adults.

If cavities aren't treated, they get larger and the decay can become severe enough to cause serious toothache pain, infection, tooth loss and other complications. You probably know that regular dental visits and good brushing and flossing habits go a long way toward preventing cavities and tooth decay. But you may be surprised to learn that cheese may also help prevent cavities, and that potato chips may be more harmful than a candy bar. Detecting and treating cavities and tooth decay early can save you pain and expense later — as well as your teeth.
