A white tongue is a description, not a diagnosis. Often, bacteria, dead cells, food particles, and mucus collect between the tongue’s tiny bumps, called papillae. Dehydration and reduced saliva overnight can make this coating more noticeable, especially if you breathe through your mouth. Smoking, alcohol, some medications, and temporary illnesses may contribute too. Drinking enough water, brushing regularly, and gently cleaning your tongue can help clear ordinary buildup and improve breath. Avoid forceful scraping, which can irritate delicate tissue.
