How to Handle a Knocked-Out Tooth

A knocked-out tooth is a dental emergency that can happen quickly—and knowing what to do in the moment can make all the difference. Whether it happens from a fall, accident, or sports injury, acting fast can sometimes save the tooth and help your dentist reattach it successfully.

If a permanent tooth is knocked out, the first thing to do is stay calm and act quickly. Pick up the tooth by the crown, which is the white part you normally see in the mouth. Do not touch the root of the tooth, as it is very sensitive. If the tooth is dirty, gently rinse it with milk or clean water, but do not scrub it or use soap.

If possible, try to place the tooth back into the socket right away. Hold it in place by gently biting down on a clean cloth or gauze. If you can’t put it back in, keep the tooth moist. The best options are placing it in a small container of milk, holding it in your cheek (if safe to do so), or using a tooth preservation kit if one is available.

Time is very important. Try to get to a dentist within 30 minutes. The sooner the tooth is reimplanted, the better the chances are that it can be saved. If you are unsure whether the tooth is permanent or a baby tooth, it’s still best to contact a dentist right away for guidance.

According to the American Association of Endodontists, quick action within the first hour gives the tooth the best chance of being saved.

Remember, a knocked-out tooth is not something to ignore. Even if you can’t reinsert it yourself, getting to the dentist quickly gives you the best chance of a good outcome. It’s also a good idea to wear a mouthguard during contact sports to help prevent these injuries from happening in the first place.
