Injuries to the mouth can cause teeth to be pushed back into their sockets. If the tooth is pushed partially out of the socket, your dentist may re-position and stabilize your tooth. If the pulp remains healthy, then no other treatment is necessary. However, if the pulp becomes damaged or infected, root canal treatment will be required. Root canal treatment is usually started within a few weeks of the injury and a medication, such as calcium hydroxide, will be placed inside the tooth. Eventually, a permanent root canal filling will be placed and the canal will be sealed.
If an injury causes a tooth to be completely knocked out of your mouth, it is important that you seek treatment immediately! It is important to keep the avulsed tooth moist. If possible, put it back into the socket. A tooth can be saved if it remains moist. You can even put the tooth in milk or a glass of water (add a pinch of salt). Root canal treatment may be needed based upon the stage of root development. The length of time the tooth was out of your mouth and the way the tooth was stored may influence the type of treatment you receive and how successful the outcome.
