A tooth can be chipped or fractured during an accident or a bad fall. A tooth that is chipped or not badly fractured can usually be handled on a nonemergency basis. A tooth that is badly fractured may have exposed nerve tissue inside the tooth. In this case, immediate attention is needed to avoid infection, abscess, and pain. Update Date: 05/28/2008Jason S.
