Fissured tongue is usually a painless condition characterized by deep grooves in the dorsum of the tongue. Although these grooves may look unsettling, the condition is usually painless. Some individuals may complain of an associated burning sensation. The exact cause is still unknown. It may be evident at birth or present in association with an underlying syndrome or condition, such as malnutrition or Down syndrome.
