Unhappy with final result, what can I do?

I went through major changes with braces. 2 months ago my dentist asked me if I was happy with my smile and I said yes. Got them off Friday, but I just now noticed that one side's teeth are still tilted inwards. It looks crooked because of that. Whatc can be done? They asked me 3 times in different appointments if I'm happy but I didn't notice it when I had braces.
