When papillae, the tiny hair-like projections on the tongue's surface, grow longer than normal, bacteria cling to them, explains Mayo Clinic. Dead skin cells hold matter such as stained food and tobacco, and the cells become trapped in the papillae. The bacteria and skin cells cause different colors to appear in the mouth. Yellow tongue may be related to dry mouth and breathing through the mouth. When a person experiences yellow tongue along with yellowing of the skin and the whites of the eyes, he may have jaundice, which is a sign of liver problems. Anyone with these conditions should see a doctor.
