A knocked-out tooth (also called an avulsed tooth) is one of the most time-critical dental emergencies you can face. Whether it happened during weekend footy, a fall at the skate park, or a bike accident, what you do in the first few minutes can be the difference between saving your natural tooth and losing it permanently.
This guide walks you through exactly what to do if a tooth is knocked out, how to store and transport it safely, and when to get to a same day emergency dentist. If you're reading this because it's happening right now, skip to the [step-by-step first aid](#first-aid-steps) below and then book an emergency appointment immediately.
Is a Knocked-Out Tooth Really an Emergency?
Yes. Avulsed teeth are dental emergencies and require immediate treatment. The good news is that more than five million teeth are knocked out every year in children and adults, but if this happens to you due to an injury or accident it doesn't necessarily mean it's lost for good — proper emergency action can save the tooth so that it can be replanted successfully and last for years to come.
The catch is speed. To save your tooth, try reinserting (replanting) your tooth right away — teeth treated within 30 minutes to one hour have the best chance of success. This is why a knocked-out tooth belongs in the same category as chest pain or severe bleeding — it needs action now, not "I'll call on Monday."
First Aid Steps: What to Do If a Tooth Is Knocked Out {#first-aid-steps}
Stay calm, and work through these steps in order.
1. Find the Tooth and Handle It Correctly
Locate the tooth immediately — don't leave it behind. Pick up the tooth by the crown (the chewing surface), not the root, and never touch the root of the tooth. Touching or damaging the root reduces the chances of a successful reimplantation.
2. Rinse — Don't Scrub
If the tooth is dirty, rinse it with water or milk to remove any dirt, avoiding soap, and don't scrub or dry the tooth. Don't rub the tooth or scrape it to remove dirt, food or blood, and don't wrap the tooth in tissue or cloth — this damages the root surface, making the tooth less likely to survive.
3. Try to Put It Straight Back in the Socket
This is the single best thing you can do. Try to put the tooth back in its socket — this is ideal because the blood vessels and supporting tissues are the best environment for the tooth, making it more likely to be saved. Gently push it back into place facing the correct way, then bite on a napkin, gauze or handkerchief to anchor your tooth in place.
Important exception: it's not a good idea to reinsert a baby tooth, as reinserting it may lead to issues with the permanent tooth that'll replace it. If it's a child's baby tooth, don't put it back — just keep it safe and get to a dentist regardless.
4. Can't Reinsert It? Keep It Moist in Milk
If the tooth won't go back in the socket, don't let it dry out. Putting your knocked-out tooth in milk is the number one way to keep it intact for your dentist, because the makeup of milk helps maintain the periodontal ligaments so you have a better chance of successful reimplantation. Milk is sterile, contains proteins and sugars that help keep the tooth's cells alive, and its pH level is conducive to preserving the viability of those cells.
Avoid tap water for storage — water can cause the cells on the root to swell and burst, which damages the tooth beyond repair. If milk isn't available, your own saliva (spat into a clean container) or holding the tooth gently inside your cheek are acceptable alternatives.
5. Control Bleeding and Manage Pain
To control bleeding, apply gentle pressure with a clean, damp cloth. Over-the-counter pain relief can help while you travel, but tell the dentist exactly what you've taken when you arrive.
6. Get to an Emergency Dentist Immediately
Don't wait to see if it "settles down" — it won't, and time is the enemy here. You should aim to see an endodontist or dentist within 30 minutes of the injury, though it's still possible to save a tooth even if it has been outside the mouth for an hour or more. Call ahead so the practice knows you're coming with a dental avulsion and can prepare to see you straight away.
What NOT to Do
- Don't scrub, wipe, or dry the tooth.
- Don't wrap it in tissue or cloth.
- Don't store it in plain tap water.
- Don't try to reinsert a child's baby tooth.
- Don't delay — every extra minute lowers the odds of successful reimplantation.
What Happens at the Emergency Dental Visit?
Once you're in the chair, the dentist will assess the socket, check for other injuries, and may take an X-ray to check for root or bone damage before deciding on treatment. If the tooth has already been reinserted, they'll confirm it's correctly positioned and likely splint it to neighbouring teeth while the periodontal ligament reattaches. If reimplantation isn't successful or possible, options such as a bridge or implant can be discussed later — but the priority on the day is always trying to save your natural tooth first.
