Dry Mouth Guide

We need saliva to moisten and cleanse our mouths and digest food. Aside from that, it also prevents infection by controlling bacteria and fungi in the mouth. Your mouth gets dry and uncomfortable when you don’t make enough saliva. Decreased saliva and dry mouth can range from being merely a nuisance to something which has a major impact on your general health and the health of your teeth and gums, and also your appetite and enjoyment of food.

A persistently dry mouth is thought to affect at least 1 person in 10, and one in 5 older people. Sometimes, a dry mouth can be a sign of more serious condition like diabetes or Parkinson’s disease. Learn more about dry mouth in this article.
