If a tooth is completely knocked out of your mouth, time is of the essence. The tooth should be handled very gently, avoiding touching the root surface itself. If it is dirty, quickly and gently rinse it in water. Do not use soap or any other cleaning agent, and never scrape or brush the tooth. If possible, the tooth should be placed back into its socket as soon as possible. The less time the tooth is out of its socket, the better the chance for saving it.
Once the tooth has been put back in its socket, your endodontist will evaluate it and will check for any other dental or facial injuries. If the tooth has not been placed back into its socket, your endodontist will clean it carefully and replace it. A stabilizing splint will be placed for a few weeks. Depending on the stage of root development, your endodontist may start root canal treatment a week or two later.
