Xerostomia is a subjective feeling of dryness in the mouth. It is also called as the DRY MOUTH.  This can range from severity, from a temporary reduction of salivary flow rate, which is relatively common, to a more permanent absence of saliva. Individual usually detect they have a dry mouth when the flow of saliva decreases to around half the normal unstimulated rate (0.3ml/min). This decrease from saliva flow rate is the result of hypo-function of the salivary glands. The glands source their fluid from the blood circulation, process it and secrete it into the mouth. Interference of blood supply to the gland, damage to its secretary function or interruption of stimuli can lead to reduced salivary production.

Xerostomia more commonly known as dry mouth is not disease in itself rather it is a symptom of many other disease and conditions. These conditions cause saliva production to decrease or stop

Importance of Saliva


Saliva moistens your mouth and helps you to swallow and taste food. It is a natural cavity fighter. For example it washes away food and plaque from the teeth. It helps to neutralize acids in the mouth that harm tooth enamel. If you have less saliva in your mouth, your teeth and gums are at increased risk of tooth decay. People with Xerostomia are also more likely to get illnesses that affect the soft tissues of the mouth such as yeast infections (thrush). In addition, your diet may be affected because you cannot taste food as you normally would.
