A dry mouth can be caused by many different things. Cigarette smoking is definitely on the list. Thus, I think quitting should be the first step towards figuring this problem out. A dry mouth can be a very uncomfortable thing.
There are other causes of a dry mouth that should also be considered. First, there are many medications that have the side effect of dry mouth. Some anti-depressants and mood stabilizing drugs can do this. If you also have really dry eyes, a condition known as Sjogren's syndrome should also be considered. This is a condition where body's immune system attacks glands that make tears and saliva which causes dry eyes and dry mouth.
I suggest that you schedule an appointment with your primary care physician
. He or she can listen to your problem an give you a rundown of the possibilities. In addition, your doctor
can give you some information on how he or she can help you with quitting tobacco. This is probably the most important thing you can do for your health long term. There are many tools that physicians have which can help you successfully quit. Newer medications have been shown to be helpful in preventing cravings for nicotine. Good luck.
