Why do my top front teeth protrude so much? (photos)

Regardless of when i clench my teeth, smile or chew, my front teeth are always outer(?) then my bottom teeth. When I talk, sing or laugh my two front teeth are exposed and make me look like a bunny. I don't know if its buckteeth but it seems so, yet other top front teeth next to the two front teeth still protrude,but they do not get noticed as my lips kinda cover them. Help from any docter is totally apprieciated.
