When I first read your question I thought “Yes! She does!” But then I watched the video.
Doesn’t seem like she has braces, although she could probably have used them!
I Googled “Pat Benatar’s teeth” to see if I could find out whether she ever had braces. The first match from Rhapsody.com said “Pat Benatar hit the late ‘70s rock scene like a teeth-and-spandex tornado”. I just had to share that because it’s so fantastic.
