I get a yeast coating on my tongue all the time without having any soreness or discomfort in my mouth. (I do get treated for it though when I have it) The only reason I know when I get it is because I see my allergist quite regularly, and he knows what he is looking for. A lot of drs don't. (although one would hope that the dr would be able to recognize it!) You can definitely get a yeast coating on your tongue without having any other symptoms. If you do get soreness in the mouth or any other symptoms associated with that, then it is probably a different kind of yeast than what I am talking about. That would be called Oral Thrush, for which you do need to see your dr.
There is also such a thing as a "tongue scraper" (I believe that is what it is called. either that or the "tongue cleanser" or something like that). It is made of plastic and is basically the same shape as a spoon. It has a handle and the round part is not filled in (so in other words, it is like the rim of the spoon but without the center) and some of them also have a bar in the middle of them. The edges are smooth so as not to injure your mouth, but it does a very good job of removing the coating. You can probably pick one up in the toothpaste aisle of any drug store. I got mine in the Vitamin Shoppe of all places. Also, you can probably ask your dentist for one. It will gently remove all of the coating from your tongue. A spoon is just as good though. I suggest using either the spoon or the tongue scraper to first remove the coating, and then brushing both your teeth and your tongue with toothpaste to get rid of any bad breath that might have been caused by the coating on your tongue. Plus, it leaves your mouth tasting minty fresh.
P.S. I can do a little diagram thingy of the tongue scraper if anyone really wants to get one but doesn't know what they look like.
