Thanks for the reply!
Well, I am already in a 0 sugar type diet - except for the natural fructose from fruits. I've been doing it for more than 6 months and my tongue stays the same.
I am also taking: Probiotics + Caprilic Acid + Oregano Oil.
You mentioned "clean up". what do you suggest I do more? The tip of the tongue is not covered. But the middle of the tongue and the back are fully white
