I got my 2 top teeth pulled out, because my dentist said I didn't have space. My teeth no longer show when I smile?

I used to have 2 fangs sticking out on the top of my teeth but my old dentist decided to pull out the 2 teeth next to my fangs. I got braces by him but I switched dentist because his braces kept falling off.I realized later,that he wasn't even a licensed orthodontist. My new ortho who is great,and said I didn't need the 2 teeth pulled out on the top. I got my braces off, and my teeth are straight, but my teeth don't show when I smile anymore like they used too. What can I do to fix this?
