Q. Hi i’ve had crooked teeth for a long time. When i was a teenager my parents couldn’t afford to get me braces, back then i didnt mind the way my teeth were i guess because i was so young i didnt care, but now i do not like smiling because my left front tooth sticks out ( i have an overjet) and its really unattractive. i am 21 years old now and i want to get them fixed but in a way scared because 3 years ago i went to an orthodontist and he told me i need 4 teeth extracted because i have severe crowding, over jet, and an over bite. i was actually hoping i would be a candidate for invislign but i wasnt. so here i am 3 years later and i want to get them fixed so bad. i just do not want to get teeth extracted. Now my question is when that orthodoctist said all that to me 3 years ago. Do you think i can be able to fix my teeth with out getting any teeth pulled out? and i just read about the 6 month smile, do you think i will be a candidate for that?.
