My dentist told me I need a root canal but the tooth doesn't hurt. Is it really necessary?
Usually when a nerve gets infected or exposed pain is a common symptom. However, there are often times when it can also be asymptomatic as well. Ironically it is usually best to perform a root canal when the tooth isn't hurting as bad. It tells us that there is less infection at the moment. This allows proper anesthetic as well as less post procedure discomfort.
