Need to Know About Dry mouth

By Nutrition Expert – Trupti Gurav,Mumbai

Saliva, or spit, is made by the salivary glands and is very important for a healthy mouth. It moistens and breaks down food, washes away food particles from the teeth and gums, and helps people with swallowing. In addition, saliva contains minerals such as calcium and phosphate that help keep teeth strong and fight tooth decay.

Dry mouth is also known as xerostomia. It occurs when salivary glands in your mouth don’t produce enough saliva. This condition causes a parched, or dry, feeling in your mouth. It can also cause other symptoms, such as bad breath, a dry throat, and cracked lips.

Dry mouth is not a normal part of aging. Dry mouth can happen to anyone occasionally—for example, when nervous or stressed. However, when dry mouth persists, it can make chewing, swallowing, and even talking difficult. Dry mouth also increases the risk for tooth decay or fungal infections in the mouth because saliva helps keep harmful germs in check.
