Just curious what this might be, I just experienced a UNBELIEVEABLY sharp pain shoot through one of my lower front teeth, its almost like I felt it shoot through my lower gum and out this tooth. Right after I felt some pain in the back of my head for a minute, a dull pain and then that was it. Could this be caused by a nerve as my neck and left arm have been in quite a bit of pain due to an injury. Or would could this simply be nerves in the teeth? Not sure what to think, I never felt a pain shoot through a tooth this sharp before, it made me completely freeze up and buckle almost.

thanks
