White Tongue Cure

I had a white coating on my tongue for many years and would just brush it when I brushed my teeth. Didn't seem all that bad. However, when I went on an anti-Candida diet (i.e. no sugar), I noticed one day that my tongue wasn't white anymore. Honey and fruit seems to be ok, though, because I have had those regularly after the appropriate time on the diet. I'm guessing that it is related to systemic yeast infection, which I have had for some time.
