Does the numbness always go away after chin implant ? I'm still number after 12 days.

I have had a chin implant 12 days ago, my chin and lower lip is still numb, my speech is different and that makes me uncomfortable and I find my smile a little odd because my lower lip doesn't stretch as much. I wonder if I should have it removed. I would also like to know if there is a way to remove the implant to insure that there won't be any deformity in the future ? Thank you
