Is it normal to have this on my teeth?
I woke up this morning to find a white spot on one of my front teeth and another on one of my canine teeth. The spots are on the bottom edges of my teeth. I brush my teeth every morning, and I usually try to brush them before bed too. I looked it up but found out it could be a number of different things. I know for a fact that they weren't there yesterday, and I just got sick yesterday and I believe I slept with my mouth open because I can't breathe out of my nose. Could this cause the spots? Is is normal to have them? And does anyone know of a way to get rid of them??
