PAIN IN TOOTH LONG AFTER ROOT CANAL. PAIN IN TOOTH LONG AFTER ROOT CANAL. I'm wondering if anyone can help me. I've been going to a dental school to get cheaper prices on my dental work. The first thing they did was to tell me I needed a root canal and so I let them do it. That was six months ago and it hurt after they did it. They kept saying the pain would wear off. I think it's also making my sinus blocked up and I have a sinus headache all the time.
