What to Do If Your Child Knocks Out a Permanent Tooth

What to Do If Your Child Knocks Out a Permanent Tooth

When a child knocks out a permanent tooth, it’s a true dental emergency, but quick action can often save the tooth.

Here’s exactly what to do, step by step.

First, Stay Calm and Act Quickly

Time is critical. According to the American Academy of Pediatrics, a knocked-out permanent tooth has the best chance of survival if it’s reinserted within 30–60 minutes

The faster you act, the better the outcome.

Step 1: Find the Tooth and Pick It Up Correctly

Carefully locate the tooth.

✔ Pick it up by the crown (the white chewing surface).
✘ Do NOT touch the root.

Dentists advise avoiding contact with the root because it contains delicate cells needed for reattachment.


Step 2: If Dirty, Rinse Gently (Do NOT Scrub)

If the tooth has dirt on it:

  • Rinse it briefly with milk or saline solution if available.

  • If neither is available, use clean water for a few seconds.

  • Do NOT scrub, scrape, or dry it.

Colgate explains that scrubbing or removing tissue fragments can damage important attachment cells.

Step 3: Try to Reinsert the Tooth (If Possible)

If your child is calm and cooperative:

  • Gently place the tooth back into the socket.

  • Make sure it’s facing the correct direction.

  • Have your child bite down gently on clean gauze or cloth to hold it in place.

Dentists confirm that immediate reinsertion significantly improves the chance the tooth will survive.

Step 4: If You Can’t Reinsert It, Store It Properly

If reinserting isn’t possible:

Place the tooth in one of the following:

  • Cold milk (best common option)

  • Saline solution

  • Inside the child’s cheek (only if the child is old enough not to swallow it)

  • A tooth preservation kit if available

Dentists explain that milk helps preserve root cells better than water.

Do NOT store it dry or in plain water for long periods.


Step 5: Get to a Dentist Immediately

Head to a dentist or emergency dental clinic right away.

Dentists emphasize that prompt dental care is essential to increase the chance of saving the tooth.

Even if you’ve successfully reinserted it, professional stabilization is still required.

Important: Baby Teeth Are Different

If a baby tooth is knocked out, do NOT try to reinsert it.

Dentists note that reinserting a baby tooth can damage the developing permanent tooth underneath

If you’re unsure whether it’s a baby or permanent tooth, bring the tooth to the dentist for evaluation.


What Happens at the Dental Office?

The dentist will:

  • Clean the socket

  • Reposition and stabilize the tooth

  • Possibly splint it to nearby teeth

  • Monitor healing over time

  • Evaluate need for root canal treatment later

Dentists explain that follow-up care is crucial because even successfully reimplanted teeth may require additional treatment.

Signs You Should Also Seek Medical Care

In addition to dental treatment, seek emergency medical attention if your child has:

  • Loss of consciousness

  • Severe bleeding

  • Signs of concussion

  • Facial fractures

Tooth injuries often happen during sports or falls, and other injuries can occur at the same time.

Quick Emergency Checklist

If your child knocks out a permanent tooth:

✔ Pick it up by the crown only
✔ Rinse gently, don’t scrub
✔ Reinsert if possible
✔ If not, store in milk or saline
✔ Get to a dentist within 30–60 minutes

Final Take

A knocked-out permanent tooth is one of the few true dental emergencies where minutes matter.

Fast, correct action can mean the difference between saving and losing the tooth permanently.

If it ever happens, remember:

Stay calm.
Protect the root.
Act quickly.
See a dentist immediately.
