Dry mouth or Xerostomia is a condition when the amount of saliva present in the mouth is reduced. This reduction can vary from a little to a lot to the total loss of saliva. The amount of saliva a normal person produces during the day is about 2 cups. The ability of a patient to detect a decrease in saliva is when the volume of saliva decreases about 50%, or down to one cup.
