My teeth are as straight as a picket fence. I never needed to get braces to straighten the pearls in my mouth. But, my brother is another story. You can see railroad ties laid across his teeth, placed there to straighten his teeth into a perfect picket fence like mine. Now he needs to use rubber bands like anchors to hold them. When he first got them he said how each tooth screamed in agony. I am glad I will never have to see those railroad ties laid across my teeth.
