Root canal is usually painful. When people are told that they need a root canal treatment, they usually think about pain. However, the pain they feel is caused by an infection in the tooth, not by root canal treatment. A root canal is done to eliminate that pain.The root canal procedure itself is painless. A local anesthetic numbs the tooth and the surrounding area.ut that does not mean the tooth is okay. Your dentist and endodontist have ways to see if the tooth's pulp is damaged or infected. If it is, then you will need root canal treatment, even if the tooth doesn't hurt. If you see something near a damaged tooth that looks like a pimple, see your dentist.
