Oh jeez yes! If you're having troubles with dry mouth, use Biotene. They make a mouthwash and mouth spray that are excellent! Don't let it get too dry in there, or all of these other lovely problems crop up! I've just found when I use Biotene religiously and rinse after eating, a lot of problems are avoided.
I've also had trouble swallowing, so I often had to take little sips of water and slowly working it down. If it's impeding eating, talk to your doctor.. if pain is keeping you from swallowing well, some magic mouthwash can help a bunch.
