A knocked-out permanent tooth is a dental emergency, but quick first aid can improve the chance of saving it. Get clear next steps for your child based on how long ago the tooth came out.
Start with when the permanent tooth was knocked out so we can help you understand what to do right now, including whether reinserting the tooth may still be possible and how urgently to contact an emergency dentist.
If your child has knocked out an adult tooth, the first priority is staying calm and protecting the tooth. A permanent tooth has the best chance of survival when it is handled carefully and treated quickly. If the tooth is dirty, rinse it gently with milk or saline if available, or briefly with water. Hold it by the crown, not the root. If your child is old enough and cooperative, placing the tooth back in the socket right away may help. If that is not possible, keep the tooth moist in milk or inside the child's cheek only if they are old enough not to swallow it. Then contact a dentist or emergency dentist immediately.
Hold the tooth by the chewing surface or crown. Avoid touching or scrubbing the root, because the root surface is delicate and important for saving the tooth.
Do not let the tooth dry out. If you cannot reinsert it, place it in milk, saline, or a tooth preservation solution if you have one. Avoid wrapping it in tissue or leaving it on a counter.
A permanent tooth knocked out in a child is an emergency. Call a dentist right away, even if the tooth has been out for more than an hour, because treatment is still important.
This is the most favorable window. Fast action may give the tooth the best chance of being saved, especially if it is reinserted promptly and handled correctly.
There may still be a reasonable chance to save the tooth, especially if it has been kept moist. Immediate dental care is still very important.
The chance of long-term survival may be lower, but your child still needs urgent evaluation. A dentist can assess the tooth, the socket, bleeding, pain, and any other mouth injury.
Scrubbing can damage the root surface. If the tooth is dirty, rinse gently for a few seconds instead of brushing or wiping it.
A dry tooth is harder to save. Milk is often a practical option at home, at school, or on the go.
If your child knocked out a front tooth and you are unsure whether it is permanent, treat it like a permanent tooth emergency and call a dentist right away.
Stay calm, find the tooth, and hold it by the crown only. If it is dirty, rinse it gently without scrubbing. If your child is old enough and cooperative, you may be told to reinsert the tooth into the socket right away. If not, keep it moist in milk or saline and contact a dentist or emergency dentist immediately.
In some cases, yes. Reinserting a knocked-out permanent tooth quickly can improve the chance of saving it. The tooth should be handled carefully and placed in the correct direction. If you are unsure or your child is distressed, keep the tooth moist and get urgent dental help.
The best chance is usually when the tooth is treated within minutes, especially under 15 to 30 minutes. A tooth kept moist may still have a better outlook than one that dries out. Even after an hour, your child still needs urgent dental care.
Milk is often the most practical choice. Saline or a tooth preservation solution can also be used. Avoid storing the tooth dry, and avoid harsh cleaning products.
An emergency dentist is often the best place for a knocked-out permanent tooth if one is available right away. If your child has heavy bleeding, severe facial injury, trouble breathing, loss of consciousness, or you cannot reach a dentist promptly, seek emergency medical care.
