Xerostomia, or also called dry mouth, is a condition wherein your salivary glands do not make enough saliva to keep your mouth wet regularly. Having this condition, it is less likely to directly affect our salivary glands. This is because xerostomia is often due to the side effects of taking certain medications or because of aging issues. It could also be a result of having radiation therapy for cancer.

The saliva is a fundamental necessity to help the mouth function, and it also has a significant function in our digestive system. It helps prevent our teeth from decaying by neutralizing acids that are produced by the bacteria in the mouth, while also limiting the growth of bacteria and washing away any food particles inside the mouth. Saliva also enhances our ability to taste and it makes chewing and swallowing easier for us. Lastly, the enzymes in the saliva help in digesting food in our stomach.

Having dry mouth or xerostomia disturbs our daily life, making it uncomfortable from time to time. But it also has a considerable impact on our general health, especially the health of our teeth and gums. Also, it spoils our appetite in the food making it less enjoyable when eating.
