Knocked Out Tooth: What to Do and When to Call an Emergency Dentist
24 October 2025
Losing a tooth can be distressing, but staying calm and acting quickly can make all the difference in saving it.
When a tooth is completely displaced from its socket, known as a knocked-out or avulsed tooth, it becomes a true dental emergency. The outcome depends on how the tooth is handled and how soon professional care is received. Providing the right first aid within minutes can often mean the difference between saving the natural tooth and facing more complex dental treatment later on.
Tooth avulsion can happen in everyday life: during sports, a sudden fall, or an unexpected knock to the face. Whatever the cause, understanding the right steps to take in those first critical minutes is essential for preserving both the tooth and surrounding tissues.
This article explains the essential steps for managing a knocked-out tooth, so you’ll know exactly how to act and protect your smile when seconds matter most.
Immediate Actions When a Tooth Is Knocked Out
In a dental emergency like this, the first few steps are critical.
When a tooth has been knocked out, every minute matters. The first priority is to ensure the patient is medically stable and to locate the missing tooth as soon as possible. Soft tissue injuries, bleeding, or facial trauma should be addressed immediately, but preserving the avulsed tooth is equally urgent.
Always handle the tooth by the crown, the visible white part, and avoid touching the root. The root’s surface contains delicate periodontal ligament fibres that are vital for successful reattachment. Even a brief period of drying can damage these cells.
If the patient is in pain, anxious, or disoriented, help them stay calm. Avoid excessive cleaning or manipulation of the tooth. The goal is to keep it in the best possible condition and reach a dental professional within 30 minutes, if possible.

What to Do If a Baby Tooth Has Been Knocked Out
For children, the management of a knocked-out tooth is different and must be handled with extra care.
If a baby tooth has been knocked out, do not try to put it back in place. Reinserting a primary tooth can harm the developing adult tooth underneath, which may lead to complications later on.
The safest step is to contact a dental clinic as soon as possible for an examination. During the visit, the dentist will check the area for soft tissue injuries and ensure no fragments of the tooth remain in the socket. Although baby teeth are meant to fall out naturally, losing one too early can sometimes affect how a child speaks, chews, or how their adult teeth eventually align.
At MGA Dental Clinic, children who experience dental trauma receive gentle and thorough care. The dental team can provide advice on pain relief, oral hygiene after the injury, and what to expect as the area heals. Getting an early assessment helps prevent long-term issues and supports a smooth, comfortable recovery for your child.
How to Handle a Knocked-Out Adult Tooth
The situation is handled very differently when a permanent tooth is involved. Here’s what to do.
When an adult tooth is knocked out, immediate action is essential. The Australian Dental Association (ADA) provides clear guidelines for the management of avulsed permanent teeth, which should be followed closely to improve the chances of successful reimplantation:
Hold the tooth by the crown only. This is the white part you normally see in the mouth. Avoid touching the root – it’s covered with delicate cells that are vital for reattachment.
If the tooth is clean, gently place it back in the socket right away. Use the nearby teeth as a guide and make sure it’s facing the correct way.
If the tooth is dirty, rinse it gently for no more than two seconds under running water, or ideally, use milk. If that’s not possible, the patient can gently suck it clean.
Once reinserted, hold it in place. Bite down gently on a clean cloth or gauze to keep it steady until you reach the dentist.
The goal is to reimplant the tooth within 15 to 30 minutes of the injury. If reinsertion isn’t possible immediately, keep the tooth preserved and see an emergency dentist as soon as possible. Acting quickly can make the difference between saving and losing the tooth.
What to Do If You Cannot Reinsert the Tooth
In some cases, reinserting the tooth immediately isn’t possible. When that happens, the focus shifts to keeping the tooth alive until you reach a dentist.
If you can’t put the tooth back into its socket straight away, the most important thing is to prevent it from drying out. The living cells on the root surface need moisture to survive, and once they dry out, the chance of successful reattachment drops significantly.
Store the tooth using one of the following methods, listed in order of preference:
Place it in milk: Milk is the best readily available option because it has a balanced pH and contains nutrients that help preserve the root surface.
Wrap it in plastic wrap: If milk isn’t available, gently wrap the tooth in plastic wrap to prevent dehydration.
Hold it inside the mouth against the cheek: This is an option only if the patient is fully conscious and able to do so safely.
Do not store the tooth in water. Water damages the periodontal ligament cells that are essential for reattachment.
Once the tooth is safely stored, head straight to an emergency dentist. Quick, professional intervention allows the dentist to clean the socket, assess the surrounding tissues, and stabilise the tooth if reinsertion is possible.
At MGA Dental Clinic, the team is trained to manage dental trauma promptly and carefully. With the right handling and immediate care, there’s often a good chance the tooth can be saved.
When the Tooth Root Is Fractured
Sometimes a knocked-out tooth might look damaged or even fractured at the root. In that case, it’s important to handle it just as carefully.
If this happens, don’t throw the tooth away – it may still be possible to save it. Try to reinsert it gently into the socket, or if that’s not possible, keep it stored in milk or plastic wrap as described earlier.
A root fracture doesn’t always mean the tooth is lost for good. With modern restorative techniques and stabilisation methods, dentists can often preserve part or all of the natural tooth structure. In some cases, the tooth can be splinted – held in place using a small support while it heals.
It’s important to have the injury assessed as soon as possible. An emergency dentist can use dental imaging to determine the extent of the fracture and decide on the most suitable treatment. Depending on the situation, this may include root canal therapy, stabilisation, or extraction if the damage is too severe. Early assessment gives the best chance of keeping the natural tooth and preventing further complications.
Common Mistakes to Avoid After a Tooth Is Knocked Out
When a tooth is knocked out, avoiding common mistakes is just as important as taking the right steps. To maximise the chances of saving the tooth, make sure to avoid the following:
Don’t touch or handle the root: The root surface is covered with living cells that help the tooth reattach.
Do not scrape, rub, or clean the root: Even gentle cleaning can remove vital tissue from the root.
Do not let the tooth dry out: Keep it moist in milk, plastic wrap, or inside the mouth against the cheek if it’s safe to do so.
Do not rinse it in water for more than a second or two: Extended exposure to tap water can harm the root cells.
Don’t store the tooth in water: Water damages the periodontal ligament and reduces the chance of successful reimplantation.
Do not delay seeking emergency dental treatment: Every minute counts when it comes to saving a knocked-out tooth.
Acting quickly and handling the tooth carefully gives you the best chance of saving it. Immediate attention from an emergency dentist on the Gold Coast can often mean the difference between keeping your natural tooth and losing it permanently.
FAQs About Knocked-Out Teeth
How soon should I see a dentist after a tooth is knocked out?
Ideally, within 30 minutes. The sooner the tooth is reimplanted, the higher the chance it can be saved.
Can a tooth always be saved after being knocked out?
If the tooth is handled carefully, kept moist, and treated promptly, there’s a good chance it can be successfully reimplanted. The outcome depends on factors such as the condition of the tooth, how long it was out of the socket, and how it was stored.
Is it safe to reinsert a tooth myself?
Yes, but only if it’s a permanent (adult) tooth and the person is conscious. Follow the ADA’s (The Australian Dental Association) guidelines and seek immediate dental assistance.
What if I can’t get to a dentist right away?
If you can’t reach a dentist immediately, keep the tooth moist. Place it in milk, wrap it in plastic wrap, or keep it in the mouth against the cheek if it’s safe to do so. Then contact an emergency dentist for urgent care.
How do I prevent knocking a tooth out?
Accidents can happen, but there are practical steps you can take to reduce the risk. If you play contact sports, wear a custom-fitted mouthguard. Around the home or workplace, try to avoid using your teeth as tools to open packaging or hold objects. Keeping teeth healthy through regular check-ups also helps, as strong gums and bone structure provide better support.
