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.
Other conditions associated with white patches or other discolorations of your tongue include leukoplakia (pre-cancerous condition), oral lichen planus (a chronic autoimmune disorder), oral thrust (a yeast infection), and syphilis (a bacterial infection from sexual contact).very now and then you notice that your tongue (usually a healthy pink) is coated in white. While a white tongue is something that can be alarming, there is no need to worry.
