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.
Of course, you can't see bad breath. If you see a coating or a color that doesn't look right, chances are you're looking at bacterial residues, a sign of halitosis. While most people brush their teeth regularly and floss once a day, far fewer realize it is just as important to clean the tongue.
