Hi Deb. I found a product for my Aunt that she uses at night. It's hard to find in the US but found it at Dentist.net. The product is GC Mouth Gel. Email me at [email protected] if you have trouble finding it and I'll send ya a link.

She says it helps her ALOT. Kinda found it by accident as I was searching for the GC tooth mousse for enamel on my own teeth. The mouth gel is a saliva replacement... aunt just ordered another tube.
