I developed a white tongue when I woke up yesterday morning. I'm wondering how to tell for certain if it is oral thrush or something else?
I'll give a little bit of a description. When I scrape at it with a plastic spoon the taste buds remain white. It is only on my tongue and I have no ulcers any where in the mouth. It does get heavier as it goes back on the tongue but even scraping back there hasn't yielded any red marks or sores underneath.
Any advice on knowing for sure what it is?
