Dry mouth

Xerostomia is not uncommon in clinical practice, especially in older people. Because saliva secretion is reduced, patients feel dry mouth, foreign body sensation, burning sensation, when chewing food, especially dry food, can not form bolus and affect swallowing. The amount of saliva secretion is small, and the scouring effect on the teeth and oral mucosa is also small, making the oral self-cleaning effect worse. Therefore, the caries rate of patients with xerostomia is higher. The taste of most patients with xerostomia is also affected, which can not effectively stimulate appetite, and will affect the function of the entire digestive system.
