Understanding Saliva: Production, Function and Dry MouthSaliva, that thin transparent fluid that keeps your mouth cool, moist and comfortable, is often wrongly forgotten when it comes to oral health concerns.

Needless to say, saliva is an essential component of a healthy oral environment. It’s essentially the best barrier that actively protects your gums and teeth against bacterial build-up and oral diseases.


The human body, when in good health, constantly produces saliva throughout the course of the day. Saliva production is best stimulated by chewing and mainly takes place in the salivary glands that sit at the bottom of the mouth. While the body constantly produces saliva all-day long, saliva production peaks in the afternoon and drops at night during sleep.


Apart from keeping the mouth moist, saliva plays many essential roles concerning oral health, which, among others include:

  • Aiding in the initial chemical digestion of food.
  • Helping in the performance of fundamental oral tasks such as tasting, chewing, and swallowing.
  • Dissolving food particles, which in turn allows the tongue to actually taste food.
  • Actively fighting against the build-up of bacteria and harmful pathogenic organisms.
  • Preventing sudden and unwanted changes in the PH level of the mouth.
  • Supplying the necessary calcium and phosphorus minerals to the teeth.

Dry Mouth

Xerostomia happens when the salivary glands are unable to make enough saliva to maintain a healthy oral environment.

Popularly referred to as dry mouth, xerostomia can easily result in a number of oral health problems, including chronic tooth decay and gum disease, when left untreated.
