It the only dry-mouth toothpaste that has worked for me.
I've been having problems with dry mouth for many years.  I have tried many products that were supposed to help, but never seemed to make much difference.  Colgate Hydris Dry Mouth toothpaste is the only one I have tried that really seems to help.  Unfortunately, it seems hard to find this toothpaste at any local stores.  Thankfully I was able to find some on Amazon.
