SILVER SPRING, Md., May 9, 2011 /PRNewswire-USNewswire/ -- Almost everyone's mouth is dry sometimes, especially during stressful times. But a persistently dry mouth may signal an underlying disease or condition, so it's important to see your doctor, says the Food and Drug Administration.
And because dry mouth can lead to tooth decay, you should see your dentist, too.
Dry mouth, known medically as xerostomia, is a side effect of more than 400 prescription and over-the-counter drugs. Older people are especially vulnerable because they may take multiple medications.
