So I have been experiencing pain in what feels like my front tooth and the tooth to the left of it. it has been going on for some time . I been to the dentist many and many of times and they always say they see nothing wrong with the tooth or gums. I did get sensitivity to the front tooth so they finally did a root canal. its been two months and the pain still comes. now when I press on the back of the tooth there is a pain. I went back to two different dentist and they still find nothing wrong. Has anyone experienced this????
