Andrew,

The old Biotene gel was the bomb. An old OCF member from a decade ago used the gel for scuba diving. He insisted slathering that stuff on made the dry tank air and underwater experience unchanged from before surgery and chemorads. The ProVantage gel is a different approach. It only takes a small amount and you spit it out while it settles in vs putting it all over the inside of the mouth.

For me, ProVantage generates a lot more "bubbly" aerated saliva. I have completely lost the ability to secret saliva from my left parotid. It just swells up and I spend a lot of time throughout the day squeezing the nerve that goes through the salivary gland to empty it so I reduce chances of infection. I use the product every time I brush plus I suck on xylitol candy through the day.

PerioSciences offered a 50% discount a while back for oral cancer survivors just for their small travel size (Chapstick size) for $12. You can check out their website and the hydrating products. I am involved in a study of theirs through my dental oncologist who is also a big supporter of OCF. He will be speaking at an upcoming OCF walk.
