It’s going to be a shock in itself if you have a tooth knocked out, but you need to be aware that if you act fast, you can actually have it popped back in. If you ask your dentist or go on line, you can get all the information you need about this situation so that you are prepared. The first thing to do is to recover the tooth from the scene and ensure that you pick it up by the crown only: rinse it with warm salty water and if possible keep it in milk. Yes, that’s practical if you’re on a sports field or on a busy street, so the way to get around this is to tuck the tooth under your tongue or by the gums and now get to the dentist, you have about twelve hours to do this otherwise the tooth won’t take again. There are hospitals and 24 hour dentists dotted around London if you can’t get to your own. Of course, if none of these options are available to you, then you will have to put the tooth back in yourself. It can be done and you are just going to have to be brave, but on the bright side, you will be saving yourself a tooth and money on getting it replaced.
