Hi...am 22 years old i asked my dentist if he thought i needed braces he said no...then i said how about retainer? he laughed and said the braces come first and if you dont need braces then you will not need a retainer... he said i will only need some whitening done on my teeth and i'll be good. i really dont like my teeth i think one or two are crooked and a lil gap in between them. what can i do ? ughhh!!! help somebody pleaseee
