White Tongue. A white coating occurs when the tiny bumps on the tongue, known as papillae, become inflamed. Inflammation usually happens because of dehydration, fever, mouth breathing or smoking. Food debris, bacteria and dead cells then get lodged between the swollen papillae and create the white coating.
