The recommended frequency of dental check-ups depends on the person’s age, oral health status, and risk factors. For adults, the general recommendation is to visit the dentist at least once every two years. If you have an increased risk of oral diseases, such as gum disease or caries, the dentist may recommend more frequent visits. For children and adolescents, an annual check-up is usually recommended so that any potential issues can be detected and treated in a timely manner.
