My family doctor said that I need an emergency root canal. My teeth were damaged during an accident a few weeks ago. My right leg and hand were fractured and I was hospitalized for a week. Recently I experience severe pain in my teeth. So our family doctor checked my teeth in detail by taking digital x rays. He suggested for the root canal treatment for the coming week. I'm totally tensed. Because will this root canal treatment harm other nearby teeth. What do you say? Does it have any aftereffects? Or is this a very painful treatment? Kindly share your insights.
