Yellow canines? - tooth whitening comparison yellow canines

I am quite white with the color of my teeth are sometimes in the future are satisfied, but it is something of grave concern me yet.

But I have some photos again recently, and looked through them, look at my dogs really yellow compared to my other teeth. When I look in the mirror, which are a little more yellow than my front teeth, but in fact visible in the pictures.

Why is this so? And there's nothing I can do about it cheaper?
