Dental Benefit, What an extremely dry mouth may be telling you
Some medications can dry out your mouth, but an extremely dry mouth is a hallmark symptom of Sjögren’s syndrome, an autoimmune condition in which moisture-producing glands in the body come under fire from white blood cells. It is most commonly diagnosed in people over 40, and 9 out of 10 Sjögren’s patients are women. It is very important that people with dry mouth see their dentist regularly, since the lack of saliva can also lead to tooth decay.
