Lynn,
I'm not sure of the name of the machine to debride the mouth out with, but it was a small air compressor with a long nozzle sprayer that they attached a small brown glass vial or put in, saline solution, in its absence several times, which was done in the radiation center exam room by the nurse. I assume not all centers do this as my first IMRT didn't, but they weren't geared toward head and neck cancer patients. My second round, at a different facility highly experienced with head and neck cancer, did it every day, either before or after the radiation session. So did the Proton Cenrer at another location.
I also was prescribed nystatin then, and used the NeutraSal rinse instead of the salt water baking soda. NeutrSal is not available anymore, but heard of SalivaMax, that has pretty much the same igediants.
I previously used magic mouth wash, which there are about 25 different concoctions and various names, but all have about 3-5 ingredients to numb the mouth. Besides that, I've used oxycodone, fetynal....and plenty of other medications to deal with whatever arised.
I hope this helps
