A dry mouth, or xerostomia, refers to a condition in which the salivary glands in your mouth don’t produce enough saliva to keep your mouth wet. A dry mouth can be caused by certain medications or ageing issues, or as a result of radiation therapy for cancer. Also, athletes, marathon runners, and people playing any kind of sports may experience a dry mouth as well. In addition to these conditions, dry mouth may also be caused by a condition that directly affects the salivary glands.
Saliva plays an important role in the oral health process. It neutralizes acids produced by bacteria, limits bacterial growth, and washes away food particles. Saliva also enhances your ability to taste and makes it easier to chew and swallow. In addition, enzymes in saliva aid in digestion.

Dry mouth signs and symptoms
Reduced salivary flow may cause difficulty in speech, swallowing, and digestion or permanent mouth and throat disorders, and also some dental problems. A reduction in the salivary flow may cause an unpleasant feeling in your mouth and you would want to consume more liquids. Your mouth might seem a little sticky and you may experience difficulty in swallowing or talking due to decreased lubrication.
You may also notice your tongue feeling rough and dry, which may lead to a burning sensation and gradual loss of taste sensations. Subsequently, it makes your gums look pale and bleed and swell up and also causes sores to form in your mouth. A dry mouth consequently leads to bad breath as a lack of saliva is unable to flush out all the residual bacteria.
Patients suffering from the dry mouth also complain of dry nasal passages, dry corners of the mouth, and a dry and itchy throat. Furthermore, a decrease in salivation can lead to dental decay and various periodontal conditions.
