Tooth decay is the damage to a tooth caused by acids produced by bacteria in plaque, a sticky layer of bacteria. These acids gradually destroy the tooth’s enamel, which is the hard outer layer of the tooth, creating cavities or holes. If not treated, tooth decay can lead to pain, infection, and tooth loss. Regular brushing, flossing, and dental check-ups help prevent tooth decay and maintain oral health.
