There is a dental clinic called Luba Slome Jerusalem Dental
Center for Children in Yerushalaim. They offer dental services
including orthodontia, at a large discount. I have found the
dentists and orthodontist to be good and conscientious.
The dental hygienist was not so good however.
BTW, they take care of adults too.
Good luck!? Here is the contact info:
