Most traumatic dental injuries occur in children, but people of all ages can be affected. Whether the injury is a result of an automobile accident, a sports mishap, an altercation or a bad fall, the severity and type of injury will determine the treatment necessary. There are a number of common injuries that occur to teeth. Many of them affect the inner soft tissues of the tooth, known as the dental pulp. When the pulp becomes injured or inflamed, root canal treatment may be needed.
