Can I still wear clear retainer after a year? (Photo)

I have a clear retainer for my upper part of my mouth, and a wire retainer for the teeth on the lower part of my mouth, I haven't worn them in a year and there's a slight pinch in one of my front two teeth, I've noticed it's very slightly longer than the other front tooth, would it be okay if I wore my retainers again? They go on a little more than half way
