Accidents happen, especially if you're playing sports. If your teeth get knocked out, there is a chance that they can be put back in by a dentist. Simply follow these steps to give your knocked out tooth the best chance:

•Hold the tooth by the part usually visible in the mouth, not by the root. Don't scrub the tooth or place it in disinfectant.
•If the tooth is clean, hold it by the white part (the bit that is usually visible) and, making sure it's the right way round, gently push it back into its socket.
•If the tooth is dirty, rinse it in milk or cold water before gently pushing it back into place.
•Hold the tooth in place by biting on a handkerchief and go to the dentist immediately for advice.

If you can't put the tooth back in, try this:
•Place it in a cup of milk or, if not available, keep the tooth in the mouth between the cheeks and gums.
•Don't let the tooth become dry and don't put it in disinfectant.
•Go to your dentist immediately. If this isn't possible, contact NHS Direct 0845 4647 to find out your nearest Accident & Emergency department that has a dentist on call.

Accidents happen, especially if you're playing sports. You can help avoid damage to your teeth by getting a properly fitted mouthguard, which your dentist can supply for you. Make sure you get a CE marked gum shield - it is not worth taking the risk.
