prevention of dental caries
"I have experienced severe dry mouth after using Pro-denRX aqueous gel for teeth brushing.  I used it for three weeks before I finally realized that my dry mouth started when I began the use of the toothpaste.  I have stopped using Pro-denRX and hope the side effects will eventually disappear.  It has only been two days since I stopped use, so it is too early to tell much.  My mouth is still severely dry."
