A cavity, or caries, is a hole in the tooth that is caused by bacteria feeding on the sugars in food and drinks. Bacteria produce acids that dissolve the minerals in the tooth, creating a cavity. Cavities can be prevented by brushing and flossing regularly, eating a healthy diet, and visiting the dentist for regular checkups.
While cavities are a common problem, they can be treated easily if they are caught early. However, if left untreated, cavities can lead to pain, infection, and even tooth loss. In most cases, cavities can be treated by a dentist with a filling, crown, or root canal.
