Debbie, do not give up on those fluoride trays, they are really essential. It may be that the upper one just needs to be trimmed some to stop the gag reflex. But fluoride is an essential part of any radiated persons future if you wish to avoid dental caries from the decalcification that is caused by radiation. The consequences of losing a tooth a few years out of treatment can be catastrophic. For sure the fluoride tastes horrible, but compared to osteoradionecrosis from a non-healing socket after a tooth is lost, it is nothing.
