Saliva is needed for the proper functioning of the tongue. A dry tongue can't taste a thing so saliva helps the tongue and our sense of taste by keeping it wet. Saliva moistens food and helps to break it down, which in turn makes it easier for the tongue to push the food to the back of the mouth for swallowing.
These are the characteristics of a fissured tongue: Cracks, grooves, or clefts appear on the top and sides of the tongue. These fissures only affect your tongue. Fissures on the tongue vary in depth, but they may be as deep as 6 millimeters. Grooves may connect with other grooves, separating the tongue into small lobes or sections.
