I suffer from an overbite and crowding teeth on the bottom. My bottom jaw is also recessive and small. It creates a profile that lacks a jaw line and makes my face look long and narrow. Will braces alone correct this? I'm hoping for more of a jaw line and chin. Along with fixing my narrow long face. My face also seems to be a little crooked. Am I too old for appliances to expand my lower jaw? Would I need premolar extraction and how will that change my face?
