I had a chin implant 7 weeks ago. While things are getting better I still have tightness on my right side, and a slightly crooked smile. It seems to get better as the day goes on but its still always there. Is this normal 7 weeks post op? My Dr. says it may never come back or it may (not a very reassuring guy). I also want to mention this is my second implant, I had my 1st one 17 years ago, replaced 7 weeks ago. The dr. mentioned there was a lot of scar tissue.
