Teeth that are knocked out of the socked for any of a number of traumatic reason are a common dental emergencies.

If the whole tooth is knocked out by some traumatic episode you should contact an emergency dentist immediately. Generally the tooth can be saved if It is repositioned back in the socket immediately, ideally in its original position, or if repositioning is not possible, placed the tooth in a moist environment (preferably whole milk). It should be repositioned in the socket within the first half-hour after extraction. Contact a dentist immediately so the tooth can be stabilized.
