Feeling regretful about my temporary veneers - advice in final veneers and adjustments? (Photo)

I’m getting veneers on my top four teeth and feel self-conscious about the temporaries. They’re longer than my natural teeth, bulky, and emphasize my overbite (told it can’t be fixed without surgery), making my smile look horse-like. Due to gaps, the width can’t be reduced much, but I’m hoping contouring could help. I’m embarrassed to go out and worried the final veneers will have the same issues. Any advice on what to ask my dentist and if anything can be done to make the temps better?
