Replying to White and Yellow blotches on teeth?

I have some yellow and white blotches on my front teeth, and I don't know what they are or how to get them off.

I don't think it is just like discoloration from not brushing enough, as I brush everyday, and I don't smoke or drink coffee or anything.

At a point I wasn't brushing my teeth very often, but for hte last 5 months or so I have been brushing them every day. Either way though, it seems like standard discoloration would be even everywhere, and would not appear in splotches.

I can take a picture if it will help. I've seen other people have these kinds of things, it seems farily common.

I want to get rid of them, not that they are too big a deal, but you know.

Ps, I realize people are going to make jokes about this. Enjoy.
