A week ago today I had a temporary crown put on lower right molar while a permanent crown is being made. When anesthegia wore off I was left in chronic extreme pain that extends from the middle of my lip and jaw to my ear and up into my eye socket. The pain is extreme but centered on the lower row of teeth where the crown was put on. Yesterday the dentist checked everything, did a second xray, and found nothing. He stated the tooth is probably dying but admitted it had shown no signs of problem upon examination other than one corner had broken off, which was the reason for the crown. There were no symptoms prior to the crown. The tooth is not sensitive to heat/cold or biting on something. Could the injection of anesthegia hit a nerve to cause this? If so, what is prognosis, treatment, and length of recovery.
