My question is that ever since I have quit smoking and had my wisdom tooth taken out, I've noticed soreness in my upper back area, and on the lower mollars there is blackening around my crowns. My mouth has a bad taste and odor to it as well. I've been using an electric tooth brush, and floss alone with listerine. Do I need to make another dentist apt. or is there something I can do to get rid of the blackness and odor? When I went to my dentist for my referel to the maxifacial surgery guy they didn't mention anything about an infection. I would of hoped that they saw anything in the back area that would of been shocking to them and would try to fix or something.
