A dental injury can happen in a split secondduring sports, a fall, or even rough play. When a permanent tooth is knocked out of a childs mouth, its a true dental emergency. Quick, correct action can mean the difference between saving the tooth or losing it permanently.
At McLevin Dental Clinic, we treat avulsed (knocked-out) teeth in children regularly and help families handle this stressful moment with confidence. This guide outlines what parents, coaches, and caregivers should do immediately after a permanent tooth is knocked out, including first-aid steps and when to seek professional treatment.
Understanding Dental Avulsion in Children
Children typically begin to get their first permanent teeth around age 6, starting with the front incisors. If one of these teeth is knocked out, it should never be considered disposableunlike baby teeth, permanent teeth are meant to last a lifetime.
When a tooth is completely dislodged from its socket, this is called dental avulsion. The periodontal ligament that holds the tooth in place is torn, and the clock starts ticking. The best outcomes occur when the tooth is re-implanted within 30 to 60 minutes.
First Aid: Step-by-Step for a Knocked-Out Permanent Tooth
1. Stay Calm and Act Quickly
Your reaction sets the tone. Stay calm, reassure the child, and focus on getting the tooth handled and back in place (or preserved) within an hour.
2. Find the Tooth and Handle It Correctly
Locate the tooth as soon as possible. Pick it up by the crown (the chewing surface)never touch the root, as this can damage important ligament fibers needed for reintegration.
3. Gently Rinse the Tooth If Dirty
If there is visible dirt or debris, gently rinse the tooth with milk, saline solution, or cold running water for no more than 10 seconds. Do not scrub, use soap, or dry the tooth with tissue.
4. Try to Reinsert the Tooth (If Possible)
If the child is alert and cooperative, gently place the tooth back into the socket and have the child bite down on gauze or a soft cloth to hold it in place. Only attempt this if you feel confidentit shouldnt be forced.
5. Store the Tooth Properly If Reimplantation Isn’t Possible
If reinsertion isnt possible or the child is in too much distress:
Place the tooth in a container of cold milk or saline solution
If neither is available, have the child hold the tooth inside their cheek (older children only)
Avoid using plain waterit can damage root cells
6. Control Bleeding
Use clean gauze or a damp cloth to apply gentle pressure to the gum where the tooth was lost. Encourage the child to bite down on it if theyre able.
7. Get to McLevin Dental Clinic Immediately
Call our office while en route. Tell us a permanent tooth has been knocked out and provide the time of the injury. Well prepare for immediate reimplantation and stabilization once you arrive.
What to Expect at the Emergency Dental Visit
At McLevin Dental Clinic, well begin with:
Clinical and X-ray evaluation of the socket
Cleaning and disinfecting the area
Reimplantation of the avulsed tooth (if not already done)
Splinting the tooth to adjacent teeth for stabilization
Discussing follow-up care including possible root canal treatment, depending on the childs age and the tooth’s development
We may also prescribe antibiotics, and if the child isnt up to date on tetanus shots, a physician consult may be needed.
When Reimplantation May Not Be Possible
Certain conditions may prevent reimplantation of a knocked-out tooth:
Tooth was out of the mouth for more than 60 minutes without proper storage
The root surface was damaged or dried out
Severe socket injury or contamination
Very young children (in rare cases, based on root development)
If the tooth cannot be saved, well discuss pediatric tooth replacement options, such as space maintainers or eventual dental implants when the child is older.
How to Prevent Future Dental Trauma in Children
Make sure your child wears a mouthguard during sports and recreational activities
Educate them on the risks of biting hard objects like pens, ice, or candy
Ensure home play areas and school playgrounds are free from trip hazards
Teach kids how to fall safely and avoid high-risk stunts
Schedule regular dental checkups to monitor eruption and alignment of permanent teeth
We also offer custom-fitted sports mouthguards at McLevin Dental Clinic for active kids in Scarborough.
