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.
If you have a white tongue due to dry mouth, you can usually resolve this condition by drinking more water, using a humidifier, or rinsing with special mouthwash. You can also chew sugar-free gum or suck on sugarless lozenges to stimulate saliva production.You should avoid smoking and reduce your alcohol consumption.f you have a white tongue due to dry mouth, you can usually resolve this condition by drinking more water, using a humidifier, or rinsing with special mouthwash.
