Braces off slight tooth discoloration?

I got my braces off today after four years and there is a little discoloration. The teeth are a little whiter where the braces WERE and more yellow everywhere else. Will this go away and the color even out? Will a dental cleaning take care of this or should I get them whiten professionally? thank you I am getting really worried and freaked out by all of this.

i think u could just get them cleaned at the dentist and it will take off the staining. if you decide to whiten down the road, i recommend polanight whitening gel, its really cheap and works miracles.
