Hi Bev, I have that problem too but found using biotene mouth wash as well
as biotene toothpaste helps also.

The biotene helps get rid of bacteria which harbors in there.    There is
oral gel as well as the other stuff the girls mentioned.

Sugar free gum is good to chew because it stimulated saliva and NO sugar in
it.   These are tricks we find out later after LOL.

The biotene taste good and does NOT bite...do not use something like
listerine, you will be dancing in the bath roon.  Even with dry mouth..

product, but never tried it.  Maybe that will help also.   You can read
about it.

other helps

What can I do?

 a.. Sip water or sugarless drinks often.
 b.. Avoid drinks with caffeine, such as coffee, tea, and some sodas.
Caffeine can dry out the mouth.
 c.. Sip water or a sugarless drink during meals. This will make chewing
and swallowing easier. It may also improve the taste of food.
 d.. Chew sugarless gum or suck on sugarless hard candy to stimulate saliva
flow; citrus, cinnamon or mint-flavored candies are good choices.
 e.. Don't use tobacco or alcohol. They dry out the mouth.
 f.. Be aware that spicy or salty foods may cause pain in a dry mouth.
 g.. Use a humidifier at night
this is the best though
