that depends on a lot of things. extractions(usual wisdom teeth) I had 4 molars taken also. the expression and bite numbers of foffice visits/cleanings. people with really messed up mouths (baby teeth not taken at proper times etc) can run into $6-7k+ you may not need braces but get away w/ invisoline. My experience was in the $5k range. overbite straightening of 3 and extractions closing gaps.
