I have pain in my lower jaw, ear, and neck. After going to my dentist, ENT, and Oral Surgeon my dentist believes I need a root canal. The same thing happed to me a couple of years ago on the left side. After 2 years of going back and forth to the dentist and finally a root canan. My dentist discovered my root was broken and I lost my tooth. Could this possibly be the same thing happening on my right side now. I am currantly on antibiotics until my root canal in 2 weeks. It is very scary especially with my neck glands feeling sore.
