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.
White tongue is the result of an overgrowth and swelling of the fingerlike projections (papillae) on the surface of your tongue.The appearance of a white coating is caused by debris, bacteria and dead cells getting lodged between the enlarged and sometimes inflamed papillae.xamples of conditions associated with white patches or other discolorations of your tongue include: 1  Use of certain medications, such as prolonged use of antibiotics that may bring on an oral yeast infection.
