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.
A tongue that looks white in patches may indicate another condition, thrush, a type of oral yeast infection. This may be caused if you have recently taken antibiotics, and itâs not uncommon in infants and the elderly.enerally, the occasional white tongue, especially when the whole tongue is white (not white in spots or patches), is due to minor inflammation of papillae, the tiny bumps that coat your tongue.
