Knocked-Out Tooth? What to Do in the First 30 Minutes

A knocked-out tooth (called tooth avulsion) is a true dental emergency. What you do in the first 30 minutes can mean the difference between saving or losing the tooth permanently. Acting fast and correctly gives the best chance of successful reattachment.

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

Step-by-Step: The First 30 Minutes Matter

⏱️ Minute 0–5: Stay Calm and Find the Tooth

• Locate the tooth immediately
• Pick it up by the crown only (the white chewing surface)
• Do NOT touch the root

Touching the root can damage the periodontal ligament cells needed for reattachment.

🚿 Minute 5–10: Clean It Carefully (If Needed)

• If the tooth is dirty, gently rinse it for 5–10 seconds
• Use milk or saline if available
• Do NOT scrub, brush, or use soap
• Do NOT dry the tooth

Never wrap the tooth in tissue or cloth.

🦷 Minute 10–15: Try to Reinsert the Tooth (If Possible)

If the person is conscious and cooperative:

• Gently place the tooth back into the socket
• Make sure it’s facing the correct direction
• Bite softly on gauze or a clean cloth to hold it in place

⚠️ Do not force it if it doesn’t slide in easily.

🥛 Minute 15–30: Store the Tooth Properly (If Reinsertion Isn’t Possible)

If you cannot put the tooth back:

• Place it in cold milk (best option)
• Or use saline solution
• Or hold it inside the cheek (adults only)

❌ Do NOT store in water
❌ Do NOT let it dry out

Get to a Dentist Immediately

• See a dentist or emergency dental clinic within 30–60 minutes
• The success rate drops sharply after one hour
• Call ahead so the clinic can prepare for an emergency visit

What NOT to Do

• ❌ Don’t delay treatment
• ❌ Don’t scrub or sterilize the tooth
• ❌ Don’t store the tooth dry
• ❌ Don’t touch the root
• ❌ Don’t assume it can’t be saved

What About Baby Teeth?

Do NOT reinsert a knocked-out baby tooth.
Doing so can damage the developing permanent tooth underneath. Still see a dentist immediately for evaluation.

Can a Knocked-Out Tooth Be Saved?

Yes — if treated fast.

• Best outcomes occur when the tooth is replanted within 30 minutes
• Proper handling and storage dramatically increase success

Final Takeaway

A knocked-out tooth is one of the few dental emergencies where minutes truly matter. Knowing what to do before you reach the dentist can save your natural tooth.

When in doubt: act fast, keep the tooth moist, and get professional care immediately.
