I’m not a health expert, so I do not recommend anything to anyone but just share my experience.  (Having lived two hundred years, it seemed, I have something that I learned through my experience over the years.)

So, dry mouth, I mean lack of saliva, is usually caused by a long-term use of medication, a medical expert says.  In my opinion, it can be also related to toothpaste and mouthwash; using too much toothpaste or mouthwash can give you dry mouth.  So, I use tiny amount of toothpaste, about less than a pea size.  As for the mouthwash, I avoid using it all together.  Why?  It can give you some side effects like, discoloration of skins in your mouth.  A doctor says that it is a normal condition as we get older.  I hope he’s right.  When I rinse mouth with cold water the skin color returns to normal a little for a while.

I’ve heard that whitened skin in the mouth can be a sign of mouth cancer.  I guess I should research on it more.  Any suggestion or information on the subject would be very much appreciated.

Don’t judge a book by its book cover.  Authors often change their book cover images as the better ones available, or, just to refresh it.
