White coated tongue is a common sign of fungal infection known as Oral Thrush. As it is mostly caused by overgrowth of fungus called Candida, this condition is also referred to as Candidiasis of the mouth and throat.
The tongue can get coated with bacteria-rich mucus, giving it a white appearance. You can gently brush your tongue with your toothbrush or use a tongue scraper to reduce the coating and any odor associated with it. If the problem won't go away, see your dentist.
