Dry mouth refers to any condition in which mouth is unusually dry. Most often, dry mouth is the result of a decrease in saliva produced by the glands in mouth (salivary glands), and it's frequently a side effect of medication. Less often, dry mouth may be caused by a condition that directly affects the salivary glands. Dry mouth is a common problem. It can range from being merely a nuisance to something that has a major impact on your general health and the health of your teeth, as well as appetite and enjoyment of food.
Change medications that cause dry mouth. If the doctor believes medication to be the cause, he or she may adjust your dosage or switch you to another medication that doesn't cause a dry mouth. Recommend products to moisturize mouth. These can include prescription or over-the-counter mouth rinses, artificial saliva or moisturizers to lubricate your mouth.
