Bad Mommy, good Mommy?

Today my little girl gets upper and lower palette expanders put on and I am torn. She cry's every time she thinks about it. I feel so bad. I tell her that she is perfect just the way she is but yet I'm trying to change her physical appearance. Isn't that lying? Do I really think she is perfect if I'm trying to change her? Does she realize this? Does it make her sad? Her teeth are shifting at an alarming rate and I don't want her to be embarrassed at her smile when she gets older. Right now she doesn't realize how bad they look and doesn't care. I see and know how fast they have moved in the past 2-3 months and worry about how much they will move in the next 2-3 months. And yeah, deep inside I think if I admitted it her teeth do bother me. They don't embarrass me but it bothers me because it does make her less than perfect physically and it is something I can fix. I am a fixer. If there is a remote chance that it can be fixed, I will try. We can save her some pain and time in braces if we start now. Does that make me a bad Mommy for wanting to fix this or a good Mommy for fixing her smile for her? Sigh. Some things are hard to figure out...
