“Crooked smile after chin surgery”

My chin was large - a little too long and wide, and very "fleshy"/fatty. I had lipo on it to make it more defined and a little smaller. A year later I decided to have the bone shaved down a little to make it look even more refined (because it was looking kind of square after the fatty tip was removed).

This was 2 weeks ago. I'm now experiencing problems with my motor nerves, in which my lip is crooked when I smile. I understand that this will heal, but I'm worried that it won't, or that it won't all the way. I want to know what the odds are that I won't regain 100% mobility.
