|Hope this doesn't sound too gross or weird...but I've noticed after a couple of long rides in sub-freezing weather, the lower half of my top front teeth turns dramatically whiter. There is a clear line across my teeth between the exposed bright white area and the less white normal color of my teeth. Clearly, it's from breathing through my open mouth. Is this bad? The discoloration goes away after a few hours back indoors.|

|Sub-freezing air is also very dry air, and you are just drying out your teeth, or at least the enamel. Dry teeth are whiter by nature. The line you see is the smile-line or lip-line, ie. where your lip rests on your front teeth normally. If you have a really prominent line, you are probably a mouth breather.
Wouldn't worry about it though, it's not a big deal. You probably only noticed because of the super dry air. Lick your teeth while riding every once in a while if you want.
