I have a condition where my front 4 teeth of the upper jaw slant outwards like \ (away from the mouth). The lower jaw has straight teeth. I visited one Ortho and he suggests I wear Palate Expander. He says if braces alone is used to straighten my teeth, then I would have an underbite and he says that my Upper Jaw is not fully arched and he needs to pull it forwards. Can I go with this treatment or, are there any other alternatives besides surgery? The jaw needs to shift 4-5mm forwards.
