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 experiences a bump filled with blood instead of a transparent fluid commonly noticed in a blister. Usually the blister on the tongue is a tiny red bump either on the surface of the tongue or any other side of tongue-back, under and or sides. Your tongue should be pink always moist and some texture on it.
