Hey, thanks for responding. I think I know what you might possibly be talking about, thanks to google images. (Bad idea to search) anyway, mine isnt white either though, it's slightly redder than my tongue but pretty much the same color of my tongue. A pinkish color, sometimes redder after chewing or talking a lot. And mine is on the right side of the tongue towards the front, I'm not sure of your location. But I will definitely keep an eye on it until the next appointment with my other dentist and then ask him for recommendations.
