How to fix my protruding/horse looking teeth? (Photo)

I have straight teeth but however I do not like the overbite horse looking appearance that I have when I smile I am looking to fix this issue as soon as possible, I am 24 years old and I would like to have perfectly shaped teeth that does not make me look like a horse or gives that "buck tooth" effect. People do not comment on it or seem to notice that aspect of it they would only say my teeth is straight but that is the least of my worry I think it makes me look unattractive Any suggestions :( ??
