As you get older, you’re more likely to experience dry mouth. That means less saliva, which is one of your body’s key weapons in defending against gum disease and tooth decay because it washes away acid and food particles. Dry mouth can be a side effect of certain medications or can stem from other conditions, such as diabetes.
According to the American Dental Association, about 30% of people over 65 and 40% of people over 80 suffer from dry mouth. Drinking water throughout the day is a great start, but you should also limit consumption of alcohol and drinks that have a lot of sugar or caffeine.
