I would be very interested to hear about this appliance that she mentioned.

All my dentists that I've seen since treatment have asked about flouride. It burns my mouth too much four years out of treatment. However, they are happy with me at least using the biotene toothpaste that has flouride in it. I also recently found a toothpast by Tom's (that natural stuff) that is for dry mouth and has flouride in it. Biotene toothpaste will still burn on occassion adn I"ve actually found that Tom's toothpaste will NOT burn, even when Biotene will. You know those lemon cookies that the girlscouts come out with? That's what it tastes like. It's like dessert when I brush after a meal LOL

A couple weeks ago I also stumbled across a product called Quantum Helath OraMoist Time-Releasted Dry Mouth Disc. I've been putting that in my mouth at night and it's been helping me.

Good luck.
