What Causes Dry Mouth?

With the exception of mouth breathing, the decrease in the amount of saliva, and the subsequent development of dry mouth, is mainly due to general body causes, not to local oral problems.
 


 

Medications: Over 1800 drugs can make your mouth feel dry. Eighty percent of the top 10 drugs may cause oral dryness. Moreover, the more drugs you take, the more likely you will be troubled by dry mouth. Prominent among these drugs are those prescribed for high blood pressure, anxiety, depression, allergies, weight loss, Parkinson's disease, pain and many more.
 


 

Diseases: Decreased saliva and dry mouth are associated with a number of medical and psychologic conditions. A prominent disease which causes oral dryness (and dryness of the eye) is Sjögren’s (“Showgren’s”) Syndrome. This is an autoimmune condition which is characterized by generalized dryness. The dryness is brought on by damage to the salivary and other similar glands. Sometimes, Sjögren’s Syndrome is associated with rheumatoid diseases e.g. rheumatoid arthritis, lupus or scleroderma ( a condition in which the skin becomes thick and less pliable). Other diseases which may result in dryness are diabetes, AIDS, bone marrow transplants, dehydration, etc.

Therapeutic Irradiation: Treatment for certain cancers of the head and neck can include radiation, which may damage the salivary glands, and decrease or completely stop the production of saliva. These effects are sometimes irreversible, but some medications may partly restore salivary function.

Ageing: As we get older our mouth tends to produce less saliva. Although this loss is probably not enough to cause oral dryness, per se, it contributes to this condition.

Decrease in our ability to Chew: Chewing, is the normal exercise of the mouth. Like with any other form of exercise, when you don’t use it, things begin to shrivel up. When your arm is in a cast, the muscles shrink in size. And so it is with the salivary glands. If you cut down on your chewing, they will decline in size and produce less saliva. And this induces dryness.

Depression: People who are depressed and/or overly anxious have lower rates of salivary flow.

Since so many factors cause dry mouth, it is evident that the determination of what causes your oral dryness is not a simple matter.
