I had a chin implant in 2007. It appears as though my chin implant has slid into the left-hand side of my jaw. This leaves the right side of my chin from about an inch inwards under the lip without an implant (I can feel this physically upon touching and I had an orthodontist appointment where we could see the x-ray showing it has slid) Do I need a revision asap before it possibly gets worse? Or can this procedure wait another year? I think this slide happened sometime in the last 24 months
