I have Candida and am working with 2 doctors and a naturopath to rid myself of it. I had the white coating on my tongue but it is now gone. My naturopath suggested I use Colloidal Silver and a tooth brush and brush it off. I did as she suggested and the white coating is gone! I swish with colloiodal silver every morning for 5 minutes and the white tongue has stayed away. Try this and perhaps it will help you.
