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.
It could mean: You have a yeast infection. A lumpy, white-coated tongue could be thrush, an oral yeast infection caused by overproduction of candida. The condition is often linked to antibiotics. âYour tongue is home to naturally occurring bacteria and yeast.
