I kind of buy it.
My daughter was supposed to have a jaw-lengthening surgery, but she refused precisely because it would lengthen her jaw and change her appearance. (The jaw-wiring was off-putting as well...)
She eventually found another dentist that sculpted her teeth so they’d better align. The procedure took about ten minutes, no pain or injections and ended years of migraines.
You have a wonderful, sensible daughter. Smart too.
