I had heard of dental trays, prescription fluoride prior to my radiation in 2011, and went to a regular dentist who said he'll take care of me. I had one or two extractions, a root canal and two fillings, and was given chlohexidine mouth rinse. I was fine with this, having a very bad experience from chemo a year earlier, so I didn't push, didnt really know better or really want high doses of fluoride hearing it causes cancer, plus my near death experience with other drugs/chemo I had at a top NYC CCC before that, so I never went back to them, and formed my own team of doctors, radiation and medical oncologist, Dentist, etc. A year after radiation, my teeth started to deminerlize, two years out most are cracked, broken, down to the gum line. I'm back to another CCC, seeing the dental oncologist for teeth removal, hyperbaric chamber. It may have happened anyway, as the chemo had caused worse dry mouth, mucocitis than radiation did, so may have been compromised already, but in retrospect, I wish I did go to a dental oncologist, gitten the dental trays, prescription fluoride.

You still can get dental trays, prescription fluoride, as some doctors start after Treatment, some before. There is also remineralization paste you can get from a dentist to help with demineralization, white spots no teeth.

Good luck.
