I Have a Gap in My Teeth?

Hey guys. I have a gap in my teeth and I've seen many alternatives online for it…. what's the best? I'm quite new to all this but I really want to get it fixed.

Thanks in advance!

Suggestion:

How old are you? I had a gap when I was in grade school and a bit into high school. As all my back teeth came in it did close up on its own and now I wouldn't say I have a gap at all.
