I have a mild profile protrusion but my teeth are straight with minimal/no crowding. I have been advised by my dentist that in order to correct the profile protrusion I need to extract 4 teeth and go on braces. Is there any other methods other than extraction?(IPR) Should I be worried that it will cause a 'dished-in' look as my protrusion is only minor? I have consulted 2 other orthodontists and they said mine is a borderline case and its up to personal choice. Can i seek ur kind advice please
