What is a "cavity"?
A cavity is a hole that forms in a tooth because of tooth damage. It occurs when bacteria in the mouth produce acids that destroy the tooth enamel, which is the hard outer layer of the tooth. If left untreated, cavities can lead to pain, infection, and even tooth loss. Regular brushing, flossing, and dental check-ups are essential in preventing cavities.
