Hello, Is there anyway to broaden my smile/ Arch of teeth and get rid of dark spaces? I went to Consult an Orhto today and was informed that invisalign alone wouldn't widen the V shaped Arch of my teeth and that i would need (SFOT) Surgically Facilitated Orthodontic Therapy along with my invisalign treatment in order to achieve the best results. Im considering the procedure, just never heard of (SFOT) or propel so i need other opinions, Is this Necessary to achieve that broad "hollywood" smile!?
