Xerostomia

Xerostomia, commonly known as dry mouth, is a condition in which the person’s salivary glands don't make enough saliva to keep the mouth wet. It is generally seen as a side-effect of certain medications, symptom of some medical disorders or as an adverse effect of radiation in cancer therapy. Rarely, the cause may be directly related to the salivary gland itself.

Saliva helps prevent tooth decay by neutralizing acids produced by bacteria, limiting bacterial growth, and washing away food particles. Saliva also enhances the ability to taste and makes it easier to chew and swallow food. Along with this, saliva contains enzymes that help in the easy digestion of food.

Decreased salivary secretion can range from minor discomfort to something that affects general wellbeing and the health of your teeth, gums, and surrounding oral tissues. Identifying the factors and causes for xerostomia creates a path for the treatment.
