A knocked out tooth can turn a fall or sports accident into a frightening emergency. If it is permanent, quick action may improve the chance of saving it. Find the tooth, hold only the white top, keep it moist, and call an emergency dentist immediately. Never place a baby tooth back into the gum.
Dr. Kat helps parents understand the next steps while their child is brought in for care.
Act Fast After a Knocked-Out Tooth
First, check that your child is awake, breathing normally, and responding. Press clean gauze gently against bleeding gums and place a cold pack outside the cheek.
Then act quickly:
- Find the tooth.
- Hold it by the white top, not the root.
- Rinse it gently only if it is dirty.
- Return it only if it is permanent and goes in easily.
- Otherwise, cover it with milk.
- Contact emergency pediatric dental care immediately.
Permanent teeth have the best chance when handled quickly, but seek care even when more time has passed.
Check Baby or Permanent Tooth
Never return a baby tooth to the empty space because this could harm the permanent tooth developing underneath. A knocked-out permanent tooth may be returned when it is safe.
Permanent front teeth usually appear during the early school years and often look larger than baby teeth. Check whether the baby tooth in that position had already fallen out.
When unsure, do not force the tooth back. Keep it moist.
Handle the Knocked-Out Tooth Safely
Pick It Up by the White Top
Hold the part normally visible in the mouth. Do not touch, rub, or squeeze the root because its surface needs protection.
Rinse It Without Scrubbing
If dirty, rinse the tooth briefly with milk or saline. Do not brush it or use soap, alcohol, or peroxide. The American Academy of Pediatrics provides a useful knocked-out permanent tooth first-aid guide.
Keep It From Drying Out
Never wrap the tooth in tissue or leave it on a dry surface. A dentist may call it an avulsed tooth, which simply means the whole tooth came out.
Put the Permanent Tooth Back?
Only try this with a known permanent tooth. Hold the white top, face it the correct way, and guide it gently into the empty space. Never force it.
If it slides in easily, ask your child to bite softly on clean gauze. Do not attempt this when a child is panicking or cannot follow directions because the tooth could be swallowed.
Dentists call this tooth reimplantation, meaning the tooth is returned to its position. Your child still needs immediate dental care.
Store the Tooth in Milk
When the tooth cannot be returned safely, store knocked-out tooth in milk inside a clean container. Cover it completely and take it directly to the dentist.
A tooth-preservation liquid or saline may also work. If neither is available, an older child can spit saliva into a clean container. Never ask a young child to hold the tooth inside the mouth.
Milk keeps the tooth moist during travel, but it does not make waiting safe.
Choose Dentist or ER
Call an emergency dentist when the main problem is the tooth, your child is alert, breathing normally, and bleeding slows with pressure.
Go to the emergency room for loss of consciousness, breathing trouble, uncontrolled bleeding, an unusual bite, or a possible serious head, jaw, or facial injury. If the tooth is missing and your child starts coughing or choking, seek medical help immediately.
A dental emergency for kids needs clear details. Tell the office when the accident happened, whether the tooth is whole, and how it is being stored.
Expect Emergency Dental Treatment
The dentist will examine the empty space, nearby teeth, lips, and gums. Digital radiography may help locate hidden damage or a missing piece.
When possible, the dentist may clean the area, return the tooth, and temporarily connect it to nearby teeth while healing begins. Follow-up visits matter because problems can develop later.
Dr. Kat guides parents through home care, follow-up timing, and warning signs. Saving the tooth cannot be guaranteed, but prompt care gives it a better opportunity.
Protect the Tooth While Healing
Offer soft foods and have your child chew on the other side. Brush gently without moving the injured tooth. Avoid hard, sticky, or crunchy foods and pause contact sports until the dentist approves.
After healing, a fitted sports mouth guard may reduce another injury. Call the dentist for increasing pain, swelling, fever, looseness, gum bumps, or darkening.
Avoid Knocked-Out Tooth Mistakes
Do not touch the root, scrub the tooth, let it dry, wrap it in tissue, return a baby tooth, or force a permanent tooth into place.
Do not delay while searching for perfect storage. Use milk and leave for the dentist. Even if an hour has passed, keep the tooth moist and seek care.

Knocked-Out Tooth FAQs
How Long Can a Knocked-Out Tooth Stay in Milk?
Milk helps keep a knocked-out permanent tooth moist during the trip, but it does not create a safe waiting period. Contact an emergency dentist immediately and bring the tooth with you, even if it has already been out for an hour.
What If I Cannot Find the Knocked-Out Tooth?
Check the ground, clothing, and inside the mouth without delaying care. Tell the dentist the tooth is missing. If your child is coughing, choking, or struggling to breathe, seek emergency medical help because the tooth may have entered the airway.
What If I Find Only Part of the Tooth?
Place the broken piece in milk or saliva and take it to the dentist. Do not push a fragment into the empty space. The dentist can check whether more tooth remains in the gum and determine whether the piece can help with repair.
What If More Than an Hour Has Passed?
Do not throw the tooth away or assume it cannot be saved. Keep it moist in milk and contact an emergency dentist now. The dentist must examine the injury before deciding whether the tooth can be returned or another plan is needed.
What If the Dental Office Is Closed?
Call the office and follow its after-hours message or emergency number. Seek an available emergency dentist. Go to the ER for trouble breathing, loss of consciousness, uncontrolled bleeding, or signs of a serious head or jaw injury.
