Hit by a netball in the face?

I was hit by a netball on the right hand side of my face between the cheek bone and lower jaw. My cheek bone has swollen up a fair bit and my jaw is increasingly painful.

I noticed that my jaw has become quite off set now with only my left hand teeth fitting together. Chewing has become difficult.

Also a few of my lower teeth have moved and are pointing in and one of my upper teeth has become loose.

How would a dentist or someone fix this?

Additional Details

I have never had braces, most of my top teeth are straight but some over lap. My bottom teeth are very jagged and over crowded, so much so that my canines have turned 90degrees and have had to have been filed by the dentist to stop cutting my lip.

I'm 14 and I have all adult teeth.

She was standing about 1 metre away from me (and a heck of a lot taller) a turned to mark my partner and at that second she did a full on chest past straight into my face. So i would say VERY hard.
