Baby tooth removed and trying to pull down the permanent one, both canines

I am 45 ,due to cavity, a cap was put on my baby canine teeth both sides, right side tooth broke, and when the xray was taken the doctor found the permanent ones a little behind on both sides, he has put braces and a surgery is done and is trying to pull down the tooth on both sides.My fear is will it come down and will it be long enough, though the dentist say it is in favourable position.
