Prefered his other teeth + some whitening. The new ones are way too white and make him look very generic in my opinion, which takes away from his appeal. Sorry but basing off these photos, they just look way too fake for me. I'm all for nice teeth, but prefer minor natural enhancements unless more drastic changes are really necessary. Of course it all depends on individual cases, but I just dont think this was necessarly a positive change to his appearance, as it's taken away from his individuality. Again, yes the old teeth needed some whitening, but they made his face much more memorable in general.
would like to see another photo of the new teeth though before I say much more.
