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.
The tongue is mainly made up of muscles. It is covered with a mucous membrane. Small bumps (papillae) cover the surface of back part of the tongue. 1  Between the papillae are the taste buds, which allow you to taste. 2  The tongue moves food to help you chew and swallow.  The tongue also helps you form words.
