Will my face really have a "sunken" look once I get a few teeth extracted?

My orthodontist told me that i'm going to have to get 4 of my premolars extracted (I just got braces). At first, I was fine with the idea, but i've been reading some things online, and people have regretted going through with this same "surgery". Can someone shed some light ? Does this only happen... show more My orthodontist told me that i'm going to have to get 4 of my premolars extracted (I just got braces).

Does this only happen to certain people who have certain cases? I have a crossbite... I don't know if that matters!

Thanks in advance for your help!
