;o) I use a waterpik to clean up the guk as well. I loved it during treatment as it cleaned my mouth and got rid of the worst stuff. Fizzy stuff, and juices are often painful and burn, post radiation, but luke warm water, (you can add the baking soda mixture or flattened club soda instead of just water)in the water chamber, on the lowest setting, cleans, helps heal, and breaks up the mucous. It will take time to see if your hubby's glands kick in and start producing saliva. It depends on the path of the radiation and any surgeries. I am okay at this point. I am dry in the morning, but during the day I'm okay - it has taken a while to get to this point. When the guk goes away - which it will - and dry mouth sets in, Biotene toothpaste, and gel helps. There are also a few meds that apparently are hit or miss.

best of luck.
