Q. Hi I had the last molar on my right side extracted just over 2 weeks ago and the extraction site is healing fine. Up until a few days ago I was finding it hard to brush the molar next to it but now I can without pain.. I was worried about decay at the back of this tooth so I used a mirror to check it and noticed it was slightly stained, upon feeling it with my finger I felt a sharp pain when my nail touched a certain part of the tooth. Could it be infected or decaying or is this normal due to the extraction?? I also have a small silver filling in the tooth so could this be a factor in causing the pain?? Please help as I am extremely freaked out and worried!,
