I had a composite filling put in one of my molars a year ago. Right after it hurt so badly that I could not eat on that side of my mouth for about two months. Since then the pain has lessened when cheweing, but it is still there, and I have become accustomed to chewing harder items on the other side of my mouth. I even went back to the dentist and she filed it a little and it did not help. I recently got my dental records from her and she covered the entire section of the tooth with filling material despite it being a small cavity. I am still having pain while chewing, and I sometimes have cold sensitivity in this tooth. What will it take to get this problem fixed?
