Those costs are in the general gap you can expect to pay. I'd recommend Invisalign only if you're worried about aesthetics.


Regarding the individual who put $20k and then was told it "didn't come out right"... sounds as if he was taken. A dentist can use a more expensive material or suggest a tougher technique which would increase the cost.. and that may have happened. That is a large sum of money for an operation on one individual.
