CANDIDA
and the Antibiotic SYNDROME
By Walter Last
Very informative
Have you considered you might have candida? I thought I might have md when I couldn't find a answer for the black specks and filaments coming out of my skin, candida symptoms list lesions but if you look up fungus that cause filaments it's says candida also produces blue, red, green, white, and grey filaments, anyways even if you don't there is treatment for tooth problems in the article above
