I went to a dentist for a toothache problem. I was told that there was a hole which was through the side of the tooth and by doing root canal treatment, the pain would go. I got the root canal treatment done and a cap also fixed on the tooth, but to my dismay the pain in that tooth still remains. Again Xray was conducted and I was given to understand that the tooth had no problem and the root canal was success. Still they could not identify the problem. What is the solution now?
