Terrib, I think you have gotten a comprehensive response. My oral surgeon / dental team who removed my molars prior to rad/chemo advised to fluoride every day...for the rest of my life to keep the remaining teeth. Rather stark advise, but since my saliva is mostly gone, and it is what in the past kept the teeth clean or washed, I get it. Sometimes if I feel ill I skip. The fluoride paste seems to upset my tummy some.

Good Luck and my prayers will be with your hubby and your family.
