Sometimes diabetes will cause this, so a doctor should draw blood and check your sugars levels.  Otherwise, dry mouth is almost always caused by a medication of some kind.  Review side effects of everything you're on, and if one says "dry mouth," well, sometimes the prescribing doc can give you someting similar without that as so much of a problem.  And sometimes over-the-counter meds will do this, like antihistimines that dry out the nose.  If you drink a whole lot of colas or juices, even orange juice, too much of those can dry out the mouth.  Alcohol consumption dehydrates a person, so if you drink a lot, cut back and don't drink daily.  Cutting back on the amount of salt you consume will help, too.  

So, get checked for diabetes, review medicine side effects, avoid things that cause dry mouth.  People should drink about 4-8 glasses of water per day, and more if they sweat when they exercise.  And a little coughdrop will ease the sensation of dry mouth.
