I have pain in my lower left 3ird tooth from the back. I have been to the dentist. They want to do root canal on the lower left side furthest back tooth.
Pain in the tooth can be due to pulpits as in your case. The pain can be radiated and show up on another area of the mouth at times. The dentist will check the X-ray of your tooth and suggest root canal. Root canal will relieve you of any pain in the tooth. Go ahead for the treatment :) hope this helps.
