Would you pull all your teeth out just because you didn't like your smile?

My friends sister had all her teeth pulled just because she thought it might look better with dentures. Before she did it, I told her she had good teeth. I gave suggestions, like maybe the dentist could just fill in a gap she had on the upper part. She seemed excited, but I told her there's no going back after you do it. Well, now that she did it, she regrets it and said she hates every single thing about it now. I wish she hadn't have done it
