What is Xerostomia?

Xerostomia is commonly known as dry mouth and it is caused by a lack of saliva in the mouth. Dry mouth is often due to the side effects of certain medications, aging issues, radiation therapy for cancer and less commonly can be caused by a condition that directly affects the salivary glands.

However, almost everyone will experience dry mouth at some point in their life, specifically in the morning if you have slept with your mouth open during the night. This is quite common and completely normal, however, if you are experiencing consistent or abnormal mouth dryness you should talk with your physician about possible causes.
