What Is Xerostomia?
5. Nerve Damage
The nerves that run through our bodies have many different functions. They help us to touch and feel, while they also help to regulate certain bodily functions, including things like how much we are salivating. This means that damage to certain nerves in the body might mean saliva isn’t produced/secreted, and this will mean xerostomia.
If you receive a sufficient enough injury to the head and neck area, then you may well end up with a dry mouth. If the relevant nerves are injured then it can also mean that other nerves are injured, so it is a good idea to let doctors know if you have not done so already.
