White tongue is a term used to describe any area of the tongue that has a grayish-white coating on it.
The entire tongue may be coated, or the coating may appear in patches.
There are a few different reasons for a white tongue, and each has a specific treatment.
A white tongue is usually a harmless symptom but, in rare cases, it can indicate a serious condition.
The most common cause of a white tongue is poor oral hygiene. Small bumps on the tongue called papillae can start to swell up and become inflamed in a mouth that is not cared for well.
