coffee turns your teeth brown.... do you drink any?
Don't try and argue that smoking doesn't show up on your teeth. Your particular case might be special, I don't know, but you can tell smokers by their teeth. I'd guess that I could tell with 99% accuracy whether someone smoked (or has smoked heavily) just by looking at their teeth.
