You can also ask your physician to test for any underlying disease or conditions that may be causing your dry mouth.  
Dry mouth is a common side effect of radiation treatment. Your mouth relies on certain glands to produce saliva, which keeps your mouth well lubricated. Radiation therapy can damage salivary glands, leaving your mouth feeling dry and parched. You may also develop cracked lips, sores, or other mouth problems. While undergoing radiation treatment, try to sip water and sugarless beverages as much as possible. Sucking on ice chips can also help. Avoid alcohol as well as coffee and other beverages that contain caffeine, which can cause your mouth and body to become dehydrated.
