Hi - I see a doctor of naturopathic medicine here in Mississauga - Ontario (he actually has his doctorate) - his wife is also a researcher at the top cancer facility in Canada - my focus wasn't particularly on my saliva though he did stab me in my glandular area under my chin, and despite being a little dry at night now for the most part during the day i have enough saliva to wet my lips and speak without difficulty. he also broke up my scar tissue all along my neck dissection area, returned blood flow to that area, and the area on either side of my jaw which helped loosen up the jaw. He stabbed me on either side of my nose and forehead (said to help with taste as well) and on my hands (for taste) my neck now is loose and probably 95-98 % and still numb in areas but thankfully it's soft and not stiff anymore.
