Braces or no?

i`m a freshman in hs and mii front teeth are crooked; the first 2 in the front are; ii don't think they are that bad tho. my dentist says all mii other teeth are perfect. SO if I was to get braces I would only have it on the top teeth. Can I just get a retainter or something else for those specific 2 teeth? I don't want crooked teeth in senior year buht I don't wanna be walkin around with braces either. So what should I do? Any other way to get "perfect teeth?"
