I found my oncology dentist to be more familiar with the coated tongue issues than my CCC team but that's why they recommended him to me. I've used diflucan pills, nizoral rinses as well as Mycelex (clotrimazole) troches for this recurrent problem and like the Mycelex the best so far. This is not really a DIY issue, so see a dentist or doctor and get a script.
