My saliva pH went to below 6, which is dangerous. It should be 7.4 in the alkaline range. On the other hand, my stomach pH which needed to be properly acidic became too alkaline, so I used digestive aids to help digest food. Everything got better except my salive readings which stayed way too acidic until recently when I went on seawater supplements (Ocean Plasma). It seems to be accomplishing what the alkaline diet, lots of lemon and lime drinks (they are alkaline-forming in spite of being acidic drinks), calcium supplementation and other efforts have failed to do, not that I would change this regimen. I just added to it.
