Hi, I had a root cannal and cap done to my top left molar 25 years ago, this week that tooth has started to hurt and is causing my face, eye, ear and head to hurt. It's been bothering me for a week, there is no abces on the gumline, could it be infected? I'm really starting to worry and know I should see a dentist but it is not easy to get an appointment where I live. Thank youView Thread
