Dry mouth describes any condition in which reduced secretion of the salivary glands results in inadequate saliva, and the saliva that is produced is thicker than normal. Depending on the severity of the problem, a person may have not only dryness in the mouth, but also increased thirst, dry lips, or, in the worst cases, difficulty chewing and swallowing. Taste and smell may be impaired. Because mouth dryness permits more rapid bacterial growth, tooth decay and gum disease are more likely to occur. Commonly, dry mouth is a consequence of smoking or a side effect of certain drugs, especially decongestants, antihistamines, antidepressants, atropine, and some heart and ulcer medications. Cancer chemotherapy and radiation therapy to the mouth and throat also cause dry mouth. To some degree, all older people experience this condition, because saliva production naturally declines with age.
Diagnostic Studies And Procedures
A doctor or dentist can often diagnose a salivary gland disorder simply by feeling the glands and noting the reduced moisture in the mouth. However, if the cause is not readily apparent, the physician may order blood tests to check for autoantibodies (antibodies that attack the body) and X-rays to check for structural abnormalities.
Medical Treatments
If an autoimmune disorder, such as lupus or Sjogren’s syndrome, is responsible for the dry mouth, treatment is direcled to controlling the underlying disease and alleviating the dryness. In severe cases, immunosuppressive drugs are given to halt the immune system attack on healthy tissue. If salivary glands suddenly become enlarged and painful, a painkiller with anti inflammatory action, such as ibuprofen or aspirin, may be advised. Anyone with dry mouth should see a dentist every three months for cleaning and periodontal treatmenLs to help prevent a potentially dramatic increase in dental cavities and gum disease. The dentist may recommend special preventive fluoride treatments that can be performed at home.
