I just noticed that the surface of my tongue and the roof of my mouth look white to yellowish in color. There arent any white or red spots, but Im wondering what this could be and if its something serious. How can I treat it? Also, Ive been feeling like theres hair or something stuck at the back of my throat for a while now. It goes away when I eat or drink but comes back later. Are these two things connected, or are they separate issues? What could this be?
