10 Causes of Dry Mouth
Cause #9: Salivary Glands
Located beneath the tongue are glands that secrete a watery substance that we know as saliva. They help to keep the mouth wet and will respond to certain stimuli such as the smell or sight of foods we like to eat. They work involuntarily and we barely even know that they are there much of the time.
If these glands are damaged or blocked in some way, though, then they may be unable to secrete any saliva, or maybe they will secrete less than usual. Sometimes, the glands might even have been removed altogether in a surgical procedure or in a severe accident.
