Usually: White tongue is a coating of debris, bacteria and dead cells on your tongue that makes it look white. Although the appearance of white tongue may be alarming, the condition is usually harmless and temporary. However, white tongue can be an indication of some serious conditions, ranging from infection to a precancerous condition. If you're concerned about a white coating call your dentist.
