Dry mouth results from an inadequate flow of saliva. It is not a disease, but a symptom of a medical disorder or a side effect of certain medications, such as antihistamines, decongestants, pain killers, diuretics and many others. Saliva is the mouth’s primary defense against tooth decay and maintains the health of the soft and hard tissues in the mouth.
Some of the common problems associated with dry mouth include a constant sore throat, burning sensation, trouble speaking, difficulty swallowing, hoarseness or dry nasal passages. Without saliva, extensive tooth decay can also occur. Your dentist can recommend various methods to restore moisture. Sugar-free candy or gum stimulates saliva flow, and moisture can be replaced by using artificial saliva and oral rinses.
