A whole tooth that has been knocked out can be kept alive and re-implanted.

Knocked out tooth












If someone is hit in the face and their tooth is knocked out, complete with its root, you should advise the person to bite on some clean cloth in order to stem the bleeding. Apply a wrapped ice pack to reduce the swelling to their face.

Adults can try to put the tooth back into place and head straight to the dentist. If it is not possible to reinsert the tooth, pick it up. The tooth can then be kept alive in milk or saliva. Transport the casualty and their tooth to a good dentist or a dental hospital and the tooth may be able to be re-implanted.

Reinsterting a tooth should never be tried with children as there is an increased risk that they may swallow it. Children should always be taken straight to the dentist along with their tooth, which is being kept alive in milk or saliva.
