A permanent tooth that is displaced after trauma should be replanted as soon as possible. The best practice is immediate replantation but this is often not done. It may be necessary to store the tooth before the tooth is replanted.
Worst practices:
(1) not preserving the tooth
(2) leaving the tooth dry and exposed
The tooth may be placed in the victim's mouth between the buccal mucosa and gingiva, but the patient must be careful not to swallow it or spit it out.
