Hey all
i was on a train to night and i got to talk to some nice girl sitting beside me. it didn't take a lot to notice that she was wearing metal on her lower teeth and clear on the upper. what i noticed then, was that her 4 upper front teeth had clear brackets, but no wire. only her side teeth had wires running from bands through brackets. so what's the purpose of having brackets on the front teeth but now wire at all?   needless to say that, anyway, this situation made her front brackets virtually invisible.
