Kerri,
I work for an orthodontist. Invisalign is great if you have the perfect bite and just want to correct a few teeth, otherwise traditional braces would be better. As far as cost depends on your case, how severe it is, could be anywhere from 2k to 6k. Invisalign has to be sent out to a lab also so be prepared to pay half of the cost of the treatment upfront. Good luck!
