Ah, I see.
In my opinion after seeing her teeth again now, it isn't so much that her front teeth are longer. It's that both her upper canines are shorter and pointier than the rest of all her teeth, they protrude outwards moreso than the others, and the gumline above them is higher. I don't think anything can be done to lower a person's gumline, but braces might change the alignment/protrusion. The pointiness could only be altered by veneers, which would probably make braces redundant. From what I can tell, the issue is mainly with those two teeth.
I feel sort of unkind talking about this, like I'm picking apart her looks. She's actually probably my favorite white female model.
