How to cope with dry mouth
Drink plenty of water.
Dehydration is one of the most common causes of dry mouth. Sipping water can also help to relieve dry mouth when it is caused by disease or as a side effect of medication.
Doctors recommend drinking eight to twelve 8-ounce glasses of water each day to keep hydrated. Drinking too much water, however, can actually dissolve the mucus lining of the mouth and worsen the symptoms of dry mouth.
