My tongue became totally white and painful overnight. My doc gave me Clotirmazole lozenge for more than 2 weeks and closys mouth wash(it contains MMS- sodium chlorite) ,and I then continued with Nystatin powder for one more week, but I did not notice any difference. Before this white tongue thing, I was using Threelac for a few days.Could this be a bacterial overgrowth caused by Threelac? Any advice or help? I feel terrible because the pain and burning does not go away.
