Coated or white tongue. Introduction. A coated or white tongue occurs when the surface is colonised by bacteria or fungi, and dead cells become trapped between the small nodules on the tongue. A coated tongue isn't a disease and isn't usually a sign of anything serious. It's usually only temporary.
There are a number of things that can cause a whitish coating or white spots to develop on the tongue, including: 1  Leukoplakia. 2  This condition causes cells in the mouth to grow excessively. 3  That, in turn, leads to the formation of white patches inside the mouth, including on the tongue. So it is important for your dentist to determine the cause of white patches on your tongue. 2  Leukoplakia can develop when the tongue has been irritated, and it is often found in people who use tobacco products. 3  Oral thrush. 4  Also known as candidiasis, oral thrush is a yeast infection that develops inside the mouth.
