My top teeth don't show when I smile - what could I benefit from? (Photos)

When most people smile, you see their entire top row of teeth. I feel like a defect because when I smile, you barely see the top teeth at all. You see more bottom teeth than top teeth even. In order for me to show top teeth, I have to exaggerate my smile (my eyes and cheeks look bad). This has been a huge source of self-confidence issues my whole life. I'm trying to figure out if I could benefit from surgery, or orthodontics, or some combination. Other face-balancing surgery suggestions?
