recently had a cracked crown replaced with a gold one on back lower left. It's actually a wisdom tooth. Next tooth forward was missing and then first molar . Dentist put gold crown on first molara and a bridge. Started having jaw pain and eustician tube pain. Went back to dentist and he xrayed and nothing showed up but he put me on antibiotics and believes there is an infection. I have no symptons of an infection except for this terrible jaw pain and it is at times severe.
