There are several traumatic dental injuries that can occur:
Fractured or chipped teeth can be repaired with simple fillings; but if the nerve is exposed, a root canal might be needed. Teeth can also be dislodged in several ways. Teeth can be pushed in, pushed partially out of socket, and malpositioned. Usually stabilizing the teeth and testing them for vitality is all that is needed. If the nerve tests abnormally, then root canal therapy might be necessary. The worst prognosis is usually associated with an avulsed tooth. This is because the supporting structures for the tooth can become irreversibly damaged. If the tooth is placed back in the socket within a reasonable period of time, then there is a chance to save that tooth. It is important to not handle the root of the tooth excessively and to place it in a moist environment. Milk, salt water, or specific solutions sold at local drug stores are good mediums for preserving the tooth. Try to get to your dentist as soon as possible.
