Turning on the Tap
When working at full capacity, saliva has many duties. This versatile fluid helps us talk, chew, and spit. It acts as a natural cavity-fighter by washing away food particles and plaque, and it lubricates food, works to buffer acids, and remineralizes those pearly whites. Saliva is vital in maintaining a healthy mouth, so when production decreases or stops, there is more than a dry mouth to pout about. Teeth and gums become more prone to decay and infection, and your taste buds might suffer in their taste-testing abilities.

Dry mouth is caused by several factors, most commonly by the use of medications. Look on almost any label of nonprescription and prescription drugs, and you'll find that dry mouth is typically listed as a possible side effect. Some of the worst offenders are those drugs designed to dry out your mucous membranes, such as antihistamines and many allergy medications. Other drugs contributing to dryness are those used to treat high blood pressure, depression, and heart disease.
Dehydration is an obvious cause of dry mouth, but dehydration doesn't always arise from the obvious reason (that is, not drinking eight glasses of H2O a day). You can become dehydrated through fever, extensive exercise, vomiting, diarrhea, burns, and blood loss.
Other causes of xerostomia are radiation therapy, menopause, surgical removal of the salivary glands, and cigarette smoking.
The primary symptom of xerostomia is, of course, a dry mouth. But this can be punctuated by myriad other conditions, including excessive thirst, a raw tongue, lip sores, difficulty swallowing, sore throat and hoarseness, bad breath, difficulty speaking, dry nasal passages, and dry lips.
But here's something to smile about: Most cases of dry mouth are easy to solve. Take a look at a few home remedies on the next page.
