caries Dental decay caused by attack on the tooth enamel by acids produced by bacteria that are normally present in the mouth. Sugars in the mouth promote bacterial growth and acid production; sucrose specifically promotes plaque‐forming bacteria, which cause the most damage. A moderately high intake of fluoride increases the resistance of tooth enamel to acid attack. See also tooth‐friendly sweets.
