Actually there is a "cure' for dry mouth caused by radiation and I know from bitter personal experience. The "cure' is to have extensive surgery and even more radiation so that you cannot swallow at all. Once that happens, your formerly bone dry mouth will be awash with mucous and since not a drop of the meager saliva you do produce will go anywhere, your mouth will fill up constantly so much that you cannot even speak with spitting every other sentence.
All things considered, I wish I had "dry mouth" again. The water bottles and Biotene mouthwash in spray bottle were doable in mitigating the dry mouth Bu then what do I know since according to NIH guidelines, I guess I am not even a survivor having not been free of Cancer for 5 years.
