Hi Sorry to hear about your daughter she seems to have a rough go of this. I know what you are going through somewhat because my husband has had Hairy Black Tongue, Canadidta, and they gave the drug that Brian suggested and are still giving it to him along with Mircle Wash. It burns and his throat hurts all the time it seems like when we clear up one bout he gets it again. Its like and on going with his mouth since the treatments. When he went to the hospital with last week they gave him massive doses of the diflucan and a antibiotic in IVs that helped the bacterial part but it has a ways to go with the fungus. I think its a problem that is going to always exist. Hope she feels better soon Bobbie
