Just a quick note to say hi! Thank you Vista. I have been asked that question before, but do not have any history of grinding my teeth. I did visit my dentist today and he is referring me to an endodondist after taking another x-ray. He said he could have gotten a little too close to the nerve when they removed the old silver filling from my broken tooth. I have very long and somewhat curved roots, so he did not want to attempt a root canal himself, but felt it better to see a specialist. I will vist the endodondist tomorrow with my x-ray and see what he thinks. My dentist said over 2 weeks was long enough to be in pain. He also said he will check my crown after the root canal and if it is not sealed well, he will redo it for me at no charge - I certainly appreciate that.
