For months, I was wondering why I was feeling extreme fatigueness, discomfort in my right ear, stomach pains, and painful migraines. Years ago, I had a root canal procedure and it always gave me discomfort. No gum infection or any abscess. I had numerous x-rays done in the past years, and it looked healthy. Surprised why every dentist I went to did not detect on the x-ray a split partial of solid black and white molar tooth. Just recently the pain appear to surface again. For months, I would get repeatedly discomfort pains that come and go. I try to avoid eating anything hard until the pain healed. I was also having medical symptoms that I had no clue it was related to the dead root-canal. A few weeks ago, I went to my dentist and asked for an x-ray and the results revealed a deep infection. I was prescribed amoxicillin for a few weeks to heal the infection before extracting the tooth. A few weeks later, another x-ray was taken and the infection was gone. The dentist advised I go to a root canal specialist to redo the root canal. I said, no way, I am not going to go through that torture again and requested that it get extracted. The tooth was extracted yesterday. I needed four shots to numb the area surrounding the bottom rear last molar root-canal tooth before proceeding to extract it. The dentist was very gentle and pulled out the giant molar tooth. The dentist said the tooth was odd because half side of the tooth was dark black and hard, while the other half side of it was white. I never seen anything like this before myself. He said that its good the tooth was pulled because it was a bad tooth that even an x-ray couldn't reveal. I am feeling so much better and no awful symptoms of fatiqueness, ear pain or migraines. I feel energetic and relieved. I am taking amoxicillin for a few days. Before the winter, I will have bridge-work done for that missing section. Since its the last molar section of the extracted tooth. Its a waste of money to plant an implant in a section that no one will notice. I want to thank my wonderful dentist that was able to extract it and end the pain.
