I need professional opinion/help with my uneven jawline, would Botox help? (Photos)

I notice I had an uneven jawline a few years ago. I got braces thinking my top and bottom teeth would align. The orthodontist said that since I'm an adult, my jaw has already molded where braces wouldn't help. I started to notice right side of my face is more slanted; my lip and jaw! I do have tmj problems like cracking of jaw when chewing. I was wondering, would botox help? Would botox make my jaw & chin look smaller? I never got filler/botox in my life so i get nervous! If anyone can help me?
