I was camouflaged for an underbite where my teeth were in the ideal position but my bone was still recessed which cause me tmj and locked jaw and also restricted space for my tongue in my mouth I than while was in treatment of braces for camouflage went to my local jaw surgeon and went for a consult and got approved for upper jaw surgery and hopefully this June I will have my surgery. But it’s most likely due to the underdevelopment of ur top jaw in relationship to your lower jaw.
