I had a dentist, a qualified person, nice guy, who did my pre radiation fillings, extractions, but he was not a dental oncologist. I did not inquire about any dental trays, special fluoride nor was it recommended, except giving me chorhexadine, even though I knew of the others preventive measures. I was scared of any additional medications, doctors, after being beat up for a year, and went the local route with treatment, instead of my CCC. As such, other contributing factors, all my teeth need to be removed sometime soon, plus doing HBOT, 20 prior, 10 after, which I did two years ago. I'm just trying to hold off as much as posdible with no dental insurance now, plus not wanting surgeru surgery until after my Pet scan, but now is effecting foods I can eat, and pain sometimes. Proper oral care, and pre-radiation dental care is very important. If there is doubt with anything, radiation can be delayed. Once radiation is given, it can't be taken back, and should not unnecessarily be stopped.
I use biotene dry mouth products, mouthwash, toothpaste, gel, spray, gum.
