Questions and Answers About Dry Mouth


Almost everyone has experienced dry mouth at some point. For some people, however, it can become a long-term problem. The clinical name for dry mouth is xerostomia (ZEE-roe-STOE-mee-uh), which is a subjective feeling of dryness in the mouth. It can occur when the glands in the mouth and throat that make saliva?the salivary glands?do not make enough of it. Lack of saliva can lead to an increased risk of:

  • Dental cavities
  • Bad breath
  • Difficulty speaking
  • Changes in taste
  • Difficulty in chewing and swallowing foods

What Can Cause a Dry Mouth?

Many things can cause a dry mouth. Temporary dry mouth can be caused by nervousness, stress, or excessive talking or singing. These situations do not typically lead to long-term problems, although they can be uncomfortable to deal with. Chronic Dry Mouth, which can lead to more severe complications, can be caused by:

?Medications: Hundreds of medications can cause Dry Mouth. Some of the most common include medicines for allergy, high blood pressure, and pain, and antidepressants and diuretics.

?Chemotherapy and radiation therapy: Cancer therapy can decrease the amount of saliva produced. Radiation therapy to the head and neck can damage the salivary glands, leading to chronic complications.

?Diseases: Certain medical conditions are associated with Dry Mouth, such as diabetes, HIV/AIDS, Parkinson's disease, and Sjogren's syndrome (a condition characterized by dry mouth and eyes).

?Nerve damage: Trauma to the head and neck can damage the nerves that tell the salivary glands to make saliva.

How Do You Protect Your Mouth from Dry Mouth Complications?
