Do I need to get my crossbite corrected? (Photo)

I had braces for a year because of delayed milk tooth extraction. Ever since I got my braces removed, I've been obsessing over my teeth. During the treatment, the orthodontist mentioned that I had a slight crossbite. He didn't say that it has to be fixed. My face doesn't look asymmetrical in general but while talking, the right side of my lips move more than the left side. The crossbite is on the left. P.S: Sorry about the bad picture quality.
