ChristineB, thanks for the info, will continue to drink lots of water, as I don't see this as a problem now, because I usually buy and drink bottled spring water and I usually drink at least 1.5 to 2 liters a anyway. And now I am drinking more.... after the 3rd Rad TX my buds and glands do seem to be SLIGHTLY less...

David, I will ask the dentist next week if twice a day trays is correct, but I think they are just being cautious (but it does take time, and I know fluoride is poison) My dentist tells me they have and are treating patients with this same issue (no salivary glands, or little production)... I was thinking the radiation path should not come out my back of the head because the RAD OC said that he has to be careful and mindful of the spinal cord..

Kris, Thanks for the reminder about stretching my jaw, I have done so and will continue, just one more great point that I discovered on this great www site.

My lovely bride is googeling the dry mouth and I think that the destruction of the salivary glands is her greatest fear (and to some degree the taste buds).

Some friends have said that they would not do all the RAD TX or even none due to the poison and gland destruction, since I had clear margins... But no one knows until...

Keep the faith.
