I went through left side lower side last but one tooth root canal first sitting. And post that my left side face is numb. Observations. 1. Not able to move my left eye brow 2. Can't wink with my left eye 3. When closing both the eyes my left eye closes almost 90 percent 4. Can eat from my left side easily 5. My mouth orientation is towards right 6. Right side of my face is more active and left side is passive 7. My left eye is dripping becomes watery quite often 4. In sleeping no problem Would like to know why this happened: What negligence my dentist did. I know she didn't do it deliberately but still to be cautious in future. Plz advise Many regards
