Could an orthodontist or oral surgeon fix my problem?

My teeth are more or less straight, its just the other aspects of my face that make it look off. When I smile, the lower teeth are visible, and the upper teeth are nearly invisible, they are obscured by the upper lip. I am very self conscious about it. Smiling feels awkward, and unnatural to me, and it feels like a huge obstacle for me socially. Any advice from an Orthodontist, Dentist, Oral Surgeon, or just someone with experience like mine would be much appreciated
