I think I have oral thrush again. I had it I believe 2 or 3 months ago as well. But yesterday my tongue started to turn white and I've been trying to eat plain yogurt and rinse my mouth with salt water. But today my tongue looks even more white. And I was wondering if there is anything I can do at home to help cure it was I can't get to a doctor for 4 more days. And if there is a way to prevent me from getting this again in the future.
