Saliva helps clean the mouth naturally. When there is less of it, the tongue's surface can feel drier and develop a more visible coating.
What matters?
Drinking water regularly, gently cleaning the tongue and maintaining good dental hygiene can improve comfort. If dryness is chronic, look for its cause instead of simply cleaning the tongue more intensely.
Some medicines and illnesses can affect saliva production, so persistent or severe dryness should be discussed with a doctor or dentist. Learn more about the causes and care of dry mouth.
