Last year (or was it early this year?) my wife talked me into taking advantage of a teeth whitening special from our dentist. The procedure involved squirting a whitening liquid or gel into some "trays"--one for my top teeth and another for the bottom teeth--and putting them in my mouth for a period of time.
Those trays were in the shape of my teeth. As I looked at the bottom tray I noticed that my bottom front teeth were somewhat crooked. I had never really noticed nor been bothered by them before, but looking at the bottom tray got me to thinking. I asked my dentist, who referred me to an orthodontist.
