Is Dry Mouth Normal?

is dry mouth normalIf you’ve ever been thirsty, extremely hot, or near dehydration, you’ve probably experienced dry mouth, which occurs when your mouth does not produce enough saliva. While inarguably uncomfortable, most cases of temporary dry mouth are resolved when you quench your thirst. Persistent dry mouth (xerostomia) is usually solved when the underlying cause of the condition is discovered and treated.

Lack of Saliva

Reduced or non-existent saliva can cause damage far beyond that of discomfort. In addition to enhancing your sense of taste, saliva makes swallowing food easier and contains enzymes that aid digestion. It also washes away food particles and assists in controlling the bacterial population in your mouth. When saliva production decreases, your risk of developing tooth decay increases. Prolonged xerostomia can cause devastating damage to your oral health, and can lead to malnutrition due to difficulty eating.

I’m Still Thirsty

When your mouth is dry, your instinctive reaction is probably to drink something, preferably water, to quench your thirst. If this alleviates your discomfort, than you can move on and continue to enjoy your day. Some people, however, may become frustrated that endless gulps of water seem to do nothing to ease their discomfort. Most cases of persistent xerostomia are caused by factors other than thirst. Some common causes for xerostomia include (but are not limited to):

  • Medications—Some medications have been known to carry the risk of dry mouth as a side effect, including anti-depression and anti-anxiety drugs, antihistamines, decongestants, muscle relaxants, and medications for high blood pressure and Parkinson’s disease.
  • Tobacco—Among the myriad consequences of tobacco use, including cancer, gum disease, and heart disease, tobacco can also cause your salivary glands to become inflamed, reducing or stopping saliva production.
