Xerostomia: the "invisible" oral health condition.

Xerostomia, or dry mouth, is perhaps one of the most underappreciated, underdiagnosed, and undermanaged oral health conditions. Recognition of a xerostomic condition is important because it can significantly affect the overall quality of life and contribute to diminishing oral health in a number of ways. This article will provide an overview of the etiology of xerostomia, the sequelae of the condition, and suggestions for pharmacological and nonpharmacological management of the condition to improve a patient's quality of life.
