I have a horrible smile; I have a wonky lip that makes me appear to have a permanent sneer. My teeth are awful, naturally yellow, now worsened by a lifetime of drinking my coffee black. I do have a white stripe across the middle of my two front teeth, but that serves only to show up the yellow (apparently my poor enamel is a result of Measles when I was very young.) I have missing teeth, such that the gap is visible when I smile, and a mis-aligned jaw that gives me an overbite that can only be corrected by some quite drastic surgery.
