Why do disorders of salivation develop?
Disorders of salivation develop for a number of reasons. Xerostonia, or "dry mouth," occurs when an individual has a reduction in the output of saliva. A dry mouth is usually produced by the intake of medications, including diuretics, antihistamines, and anti-hypertensive drugs. Hundreds of different medications can produce this condition. Another cause of dry mouth is Sjogren's syndrome, which is an autoimmune disorder. This condition is characterized by disabled salivary glands and tear ducts. Finally, peripheral and central nerve damage can cause a disorder of salivation.
