Found this term while reading through some journal articles for a paper, and I’m all about sharing the knowledge.
Xerostomia is the medical term for the subjective complaint of dry mouth due to a lack of saliva. Xerostomia is sometimes colloquially called pasties, cottonmouth, or doughmouth. Xerostomia is also common in smokers.
Xerostomia can cause difficulty in speech and eating. It also leads to halitosis and a dramatic rise in the number of cavities, as the protective effect of saliva’s remineralizing the enamel is no longer present, and can make the mucosa of the mouth more vulnerable to infection.
Other causes of insufficient saliva include anxiety, medications, or the consumption of alcoholic beverages, physical trauma to the salivary glands or their ducts or nerves, dehydration caused by lack of sufficient fluids, excessive breathing through the mouth, previous radiation therapy, and also a natural result of aging
