I've been having problems with a bad pre-molar on my upper right side. My ear on that side, just above the tooth feels full, and I have a sore throat. Its been like this for months! Since at least May. I got a root canal in September and no change, just constant burning aching pain. Dentists I go to, I've gotten second opinions and they say they don't see much wrong. They tell me each time to stick with the root canal, it should eventually feel better and its better for my long-term health....but is it time to get it pulled? I'm wanting to keep getting teeth pulled until it feels better!
