What Causes Dry Mouth?
Posted on November 4, 2008 9:18AM in General Dentistry
Dry Mouth, called xerostomia, results from an inadequate flow of saliva,
and is a symptom rather than a specific disorder. Adequate salivary
flow lubricates oral tissues, cleanses the mouth and begins the digestive
process as foods are chewed. When salivary flow is reduced, harmful
organisms grow in the mouth. Left untreated, dry mouth may lead to oral
yeast infection, a burning sensation, rampant tooth decay, bad breath
and other oral health problems. Chronic dry mouth can make swallowing
difficult. Drying irritates the soft tissues, which can make them inflamed
and more susceptible to infection. Without the cleansing and shielding
effects of adequate salivary flow, tooth decay and periodontal (gum)
disease become more common. Constant dryness and the lack of protection
provided by saliva contribute to bad breath. Dry mouth also causes dentures
to become uncomfortable. Prescribed and over-the-counter medications are
the most common cause of dry mouth. These include antihistamines,
decongestants, pain killers, diuretics, anti-hypertensives and
anti-depressants. Dry mouth also may result from radiation treatment for
head and neck cancers, salivary gland disease, emotional stress, and auto
immune diseases. Pregnancy and menopause have also been associated with
dry mouth. Increasing fluid intake might alleviate dry mouth. Your dentist
or physician may recommend using artificial saliva-available at local
pharmacies to keep oral tissues moist. Other remedies include sugar-free
gum or candy (to stimulate salivary flow); frequent sips of water;
alcohol-free oral rinses; restricted intake of caffeine, alcohol and
carbonated beverages.
P.S. Regular dental checkups are important, too. Taking good care of your
teeth and gums is critical if you have dry mouth to minimize decay and
periodontal disease. Brush and floss twice a day. Your dentist may
recommend additional fluoride products to help control tooth decay.
