Braces or no braces?

This is a question that needs answering. Even though it is an issue regarding my daughter, I would like to know your opinions if you were to step into her shoes.
When my daughter got her braces on, she had crowding. There was a possibility that they could move on with out pulling teeth, or move on with pulling 4 adult teeth. By December the orthodontist was supposed to know if teeth were to be pulled or not. It is now April, and we need some answers!
Here’s what he told me as of Monday. Her teeth wouldn’t and couldn’t move anymore. They were close enough to normal that she could just take them off and they’d be fine. OR she could leave them on and get those 4 adult teeth pulled.
I find this an extremely tough decision to make! As does she. I think that taking the braces off would be fine. Her smile makes up her. She’ll have a nice teethy smile that gives her character. Her teeth are a little flared, but nothing too bad. It’s just the crowding that the doctor is worried about.
However, having a nice smile is important too. Perfect teeth, with a little more waiting. Perfect teeth. Ahhhhh.
Then these questions come to mind… Will the waiting be worth it? Will her new perfect teeth be nice, even though they will look the same as everyone else who had braces? Will her slightly crooked front teeth be okay enough?

I’m no orthodontist here though. So what would yo do if you were put in this situation?

Of course though, we still need a little bit more information. How far away are her teeth from “normal”. Close enough? How much longer would she have to wait if she had decided to get the teeth pulled? etc. Anyways. What would you do?
