Dryness of the mouth can be lessened by using sugarless gum or mints, taking frequent sips of water or melting ice chips in your mouth. If you have drinks with alcohol or caffeine, you may want to have fewer, as they may also worsen the dryness.
Your dentist may suggest a saliva substitute or medication that can be used to help relieve dry mouth. Some products are available over-the-counter at drugstores. Or your dentist may prescribe a medication for you.
