My 16yo daughter has just been through 2 years of fixed brace treatment with a private orthodontist. The braces were removed today, but we've realised that the upper teeth are flaring out slightly - it, not coming straight down at a 90 degree angle. We went back to the orthodontist to discuss just now but he has said that because her bite with the lower jaw teeth is so close, he can't straighten the top teeth fully without extraction. Obviously we don't want that. I've included a picture that is pretty much what it looks like now.
Is it a bad job or is he right?
