Definition


The tongue is a muscular organ with sensory function that enables taste and plays a major role in phonation, the ability to speak, and the early stages of food intake. A coated tongue is a tongue lined with a whitish coating. It can be a sign of a digestive disorder but also of poor oral hygiene. Brushing the tongue has no effect on the deposit. Suspicions of some abdominal conditions such as appendicitis, may be strengthened when coated tongue appears, but this sign has no certain value.
