The dentist brought it up. Usually dental insurance doesn't cover it, he said you have to get ortho insurance. We are actually adding the kids to DH's plan next month, and if you don't sign up for the dental now, you can't do it unless there is an 'event'. But it specifically excludes ortho. So that won't help anyway. Googling yields some results with info about ortho ins, but not necessarily from companies that you can purchase it from.
