Does it hurt to have a root canal?

a woman covers her mouth | root canals st. paul MNRoot canals have gotten a lot of bad press over the years. The most common reason for the need for root canal treatment is pain and/or infection in a tooth. The treatment, a root canal, often removes the pain and is not the cause of pain. After completing more than 10,000 root canals in my experience most root canal procedures are painless with little or no post-operative pain.
