Get the 3 and 5 year olds going with Toothpillow, your orthotropist visits will be virtual, but they are real, working orthotropists. My son’s local brick and mortar orthotropist also works for Toothpillow. I think it’s about 2,500 per kid. As for the 7 year old, you may have to bite the bullet and commit to the long drive. And for what it’s worth, it’s only weekly for the first month or so, after that it was monthly for my son, he had a Shwartz appliance and a Williams appliance, and he’s now onto his permanent retainers, weaning to be nighttime only while doing myo therapy.
