Celebrities who have fixed their teeth -- and those who haven't

3 of 10: Crystal Bowersox, an 'American Idol' finalist in early 2010, had during her time on the show been criticized by many for her gap-toothed look and even received a 'rude' offer from a dentist to fix her teeth for free. She declined. But in July of that year, she debuted a new smile.

'I had braces when I was young and I couldn't afford to finish treatment," she told People magazine. 'Its not that I didn't want to do it. I've always wanted to do it. I'm smiling with pure confidence for the first time in my life. And it's a good thing.'
