What are the signs and symptoms of fissured tongue?
Fissured tongue affects the top surface of the tongue and often extends out to the edges of the tongue. The size and depth of the fissures vary and when particularly large and deep the fissures or grooves may be interconnected, separating the top surface of the tongue into what may look like several lobules. The condition is not usually painful unless debris such as food gets trapped within the grooves or when it occurs in association with geographic tongue.
