We like keeping it in the family and, with Jeffrey, we did. When we saw him for a consult he told us how impressed he was with the way we were able to resolve his sisters issues with Invisalign. He liked what he saw, but was convinced that Invisalign wouldnt work for his severe underbite (which gave him the classic Bulldog look) and jaw joint pain in the bargain. In fact he expected us to throw our hand up in despair and agree with him. Of course, though, we didnt. We knew better! When we were able to convince him that it would work and that he wouldnt have to have jaw surgery, he actually jumped for joy. In a little less than two years time we were able to accomplish the esthetic and functional outcome we had expected all along; Jeffreys Bulldog look was gone, along with his jaw joint pain. Now he and his sister look like siblings with a smile.
