A root canal does not kill the tooth, and after a root canal is complete, the tooth will be able to function as it normally does. However, root canals do remove the nerves inside the tooth, but these nerves serve very little function in a fully formed tooth.
In a root canal procedure, we have to access the pulp chamber, which means we have to remove some enamel and dentin. Whenever we do this, we are obviously weakening the tooth. But we don’t leave your tooth weakened. Once your tooth is completely treated, your dentist may put a crown on top of it. The idea here is to prevent future damage to an already delicate tooth. The result is a tooth that is as strong or stronger than it was before we began treatment.
