Aging plays a major role in dry mouth syndrome. Over time, the salivary glands secrete less saliva and the brain becomes less responsive to thirst cues, leaving your mouth and body feeling dehydrated. Although the following dry mouth remedies aren't exactly a "fountain of youth," they can certainly help counteract the effects of dehydration.
Drink plenty of water. The Institute of Medicine recommends drinking three liters of water per day for men and two liters for women. Keep in mind that the amount of water you need depends on how much exercise you get, the climate of your environment, and whether you have health conditions such as heart, liver or kidney disease, which can limit your intake of water.
Eat water-rich foods. Ideally, the foods you eat should provide about 20 percent of your fluid intake. Eat foods such as watermelon, cucumbers, peaches, nectarines and even popsicles, to ensure that you're getting the fluids you need.
Limit caffeine and alcohol intake. Drinks that contain caffeine or alcohol are dehydrating and can exacerbate dry mouth. Instead of reaching for soda, coffee or tea throughout the day, drink water or juice. When drinking alcohol, be sure to have at least one glass of water after every cocktail, beer or glass of wine.
Use a humidifier. Living in a hot, dry climate can leave you feeling more dehydrated than if you lived in a temperate environment. Use a humidifier while you sleep to help boost moisture in your mouth and on your skin.
