Dry mouth doesn’t happen only if you’re dehydrated. Many medications and health conditions can cause dry mouth, with symptoms such as difficulty speaking, chewing, and swallowing. What can you do to lessen the symptoms and prevent oral health problems? Reducing intake of caffeinated and alcoholic beverages can help, as can sucking on sugar-free candies and using a room humidifier. Your pharmacist can offer additional tips, help you choose an appropriate OTC saliva replacement, and perhaps even suggest a change to your medications.
