What else can I do to fix teeth appearance, particularly when talking, besides regular cleaning?

I feel like I'm showing too much teeth or not enough teeth (think the movie Mud but my teeth are straight). Should I try to hold a full smile more when I talk so my bottom teeth show too? Because I think by default only the bottoms of my top teeth show and it looks funky. I think I naturally cover my bottom teeth when I talk from muscle memory and wanting to hide my teeth pre-invisalign.
