Geographic tongue recurrence is generally associated with genetic factors, psychological factors, and local irritation. Geographic tongue is a congenital hereditary condition, commonly seen in infants and young children aged 6 months to 3 years. This condition may last for several months or even a lifetime, but it does not pose any threat to the patient's life. Infants with geographic tongue usually have no symptoms, although discomfort may occur after consuming certain irritating foods.
