If an "adult" tooth is knocked out, don't panic, but act quickly following these simple steps and you may save a smile.
1.Find the tooth: hold the tooth by the crown (the part usually visible in the mouth) not by the root (the pointed end). Do not scrub the tooth or place it in disinfectant.
2.If the tooth is clean: hold it by the crown and gently push it back into the socket making sure that it is the right way round. This is usually painless if done immediately after the accident.
3.If the tooth is dirty: rinse it in milk or cold water before gently pushing it back into place.
4.Hold the tooth in place: ask the child (or adult) to bite on a handkerchief and got to the dentist immediately for advice.
If you can't put the tooth back in:
1.Place it in a cup of milk. When milk is not available, place the tooth in the mouth between the cheeks and the gums. Do not let the tooth become dry. Do not place the tooth in disinfectant.
2.Go to your dentist immediately. If this is not possible, go to your hospital casualty department and ask to be seen by the dentist on duty.
