White Tongue: A white coating on your tongue could mean that you are dehydrated. It can also be caused by smoking or drinking alcohol. A white coating can also be a sign of thrush, which is an infection of the mouth with the yeast Candida albicans.
Your tongue is a great indicator of the health of your digestive tract and liver. Having a coated tongue usually means you have poor digestion or too many bad bugs in your bowel and/or a sluggish liver. It may also cause bad breath of which you may be unaware.
