Why drinking water does not resolve CHRONIC dry mouth
Take (a liquid) into the mouth and swallow.
Drink (something) by taking small mouthfuls.
The definition of drinking (or sipping) clearly tells you why drinking water is an unfortunate belief by the medical community who consistently relates this faux pas to their patients suffering from chronic dry mouth.
In order to relieve chronic dry mouth by drinking one would need to place a small water hose into their mouth and let it run almost twenty-four hours a day. As you can see, this is both impractical and illogical.
Let me explain
How the salivary system works

The salivary glands produce saliva, which keeps the mouth and other parts of the digestive system moist. It also helps break down carbohydrates (with salivary amylase, formerly known as ptyalin) and lubricates the passage of food down from the oro-pharynx to the esophagus to the stomach.

Saliva is a watery substance formed in the mouths of animals, secreted by the salivary glands. Human saliva comprises 99.5?% water plus electrolytes, mucus, white blood cells, epithelial cells (from which DNA can be extracted), enzymes (such as amylase and lipase), antimicrobial agents such as secretory IgA and lysozyme. The enzymes found in saliva are essential in beginning the process of digestion of dietary starches and fats. These enzymes also play a role in breaking down food particles entrapped within dental crevices, thus protecting teeth from bacterial decay. Furthermore, saliva serves a lubricative function, wetting food and permitting the initiation of swallowing, and protecting the mucosal surfaces of the oral cavity from desiccation.
Produced in salivary glands, human saliva is 99.5% water, but also contains many important substances, including electrolytes, mucus, antibacterial compounds and various enzymes.
There is much debate about the amount of saliva that is produced in a healthy person per day; estimates range from 0.75 to 1.5 litres per day while it is generally accepted that during sleep the amount drops to nearly zero. In humans, the submandibular gland contributes around 70-75% of secretion, while the parotid gland secretes about 20-25% and small amounts are secreted from the other salivary glands.
I personally contest the statement that the flow drops to nearly zero when sleeping. The statement is spoken in relative terms which is not measurable. At the time of this writing my personal experience is, is there is near zero saliva flow during sleeping, then I simply do not sleep. My sleep pattern is severely damaged resulting in little to no productive sleep. Therefore, there is a quantitative flow of saliva while sleeping.
Sleeping, lack there of, appears to be the number one reason why those suffering from chronic dry mouth choose relief, otherwise, one is awaken by a very debilitating, painful experience, interrupting sleep.
