Xerostomia
Xerostomia is dryness of the mouth due to lack or absence or saliva. This can lead to deterioration in oro-dental state and in the gastrointestinal system.
Causes of xerostomia
Xerostomia has many different causes. In particular these include:
- side effects of some medicines or some therapies (radiotherapy);
- some diseases (for example Sjögren's syndrome);
- excessive anxiety;
- smoking ;
- dehydration, etc.
Saliva is produced by three different glands: the parotids (1), submaxillary (2) and sublingual (3). Xerostomia develops when these glands no longer produce enough saliva. © US administration, DP
