I had braces for 1.5 years and got them off 2 years ago. Did the traditional braces where i had 4 teeth extracted and shifted inwards. Though right after i removed it, sunken cheeks and hollow smile were not that apparent but right now, it is! Particularly how sunken in my lower lip, upper lip looks and the cheek look! cheeks became super deferent. I want to know if i can improve my profile by pushing upper and lower lip forward. Through invisalign, veneers ??
