2. Cancer Treatment
There are few more frightening things in life than a cancer diagnosis. Part of the problem is that many of the treatments used to treat cancer take a toll on the body. In fact, researchers from the National Institute of Dental and Craniofacial Research have found that dry mouth is a common side effect of many chemotherapy drugs.
This is because those drugs affect the development of saliva in the mouth. The good news is that this is often temporary, with production of saliva returning to normal once the body adapts to the treatment or the treatment is completed. Of course, this will vary from case to case.
