What causes dry mouth?
Dry mouth is caused by a decrease in the amount of saliva in the mouth when the salivary glands do not work properly. The salivary glands help keep your mouth moist, which helps prevent decay and other oral health problems.
Dry mouth may be a sign of a serious health condition or may occur when a person is upset or experiences stress. Studies show that up to 400 medications, prescriptions and over-the-counter, can contribute to symptoms associated with dry mouth. The most common troublemakers are antihypertensives, antidepressants, painkillers, tranquilizers, diuretics, and antihistamines.
