I've been 98% clear after over a year with severe orange tongue. I found that taking 3 probiotics a day (3 different probiotics meaning different brands because they have different cultures), plus using a tongue scrapper has been my savior. I also found out that when I eat anything with sugar it flares up. Your tongue goes 1/2 way down your throat and since you can't get to it to scrape the fungus off, it comes back but less each day. My doctor was amazed how it went from a Colliflower orange thick coat to looking like a normal tongue. I also use charcoal toothpaste and a strong mouthwash. I still have tingling on the tongue. I think I will go to my doctor and see if he will give me penicillin if it worked for you.
