When was the last time you looked at your tongue? The appearance of your tongue can tell you a lot about your oral health. For instance, the appearance of a white film can be an indication of bad breath. When food particles, bacteria, and debris get trapped in the papillae (the tiny dots on the surface of the tongue), it causes a white coating and an unpleasant smell. Good oral hygiene is the best way to avoid and treat this. Take time to gently clean your tongue with a tongue scraper after brushing your teeth.
Thick white coating or patches of white on the tongue may be a sign of oral thrush, an infection caused by an overgrowth of the candida fungus. Leukoplakia is another condition marked by a white-coated tongue, which can be an early indicator of oral cancer. Be sure to speak with your dentist or medical professional if white spots on your mouth do not resolve on their own within two weeks. They can determine the cause of your white tongue and recommend the best treatment option.
