Knocked-Out Tooth: What to Do in a Dental Emergency

Introduction

A knocked-out tooth, also known as tooth avulsion, is a dental emergency that requires immediate attention. Quick and proper action can sometimes save the tooth and prevent long-term damage. Whether it happens from sports, accidents, or falls, knowing what to do can make all the difference.

Step 1: Stay Calm and Handle the Tooth Carefully

  • Pick up the tooth by the crown (the chewing surface), not the root.

  • Avoid touching the root to prevent damaging cells needed for reattachment.

Step 2: Rinse the Tooth Gently

  • Rinse the tooth under cool running water if it’s dirty.

  • Do not scrub the tooth or use soap/chemicals.

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

  • Gently place the tooth back into the socket, making sure it faces the right way.

  • Bite down gently on a clean cloth or gauze to hold it in place.

  • If reinsertion isn’t possible, move to Step 4 immediately.

Step 4: Keep the Tooth Moist

  • Keep the tooth moist at all times to increase chances of survival.

  • Options include:

    • Placing it in milk (preferred)

    • Storing in saline solution

    • Using saliva (inside your cheek if nothing else is available)

  • Avoid storing in plain water for long periods—it can damage the root cells.

Step 5: Seek Emergency Dental Care Immediately

  • Time is critical—ideally within 30–60 minutes of the injury.

  • Contact a dentist or emergency dental clinic immediately.

  • Bring the tooth with you in the container with milk or saline.

Additional Tips

  • If the knocked-out tooth is a baby tooth, do not attempt to reinsert—it can damage the permanent tooth underneath.

  • Control bleeding by gently biting a clean cloth on the socket.

  • Avoid touching other teeth or areas of trauma to prevent further injury.

Key Takeaway

A knocked-out tooth is a true dental emergency. Quick action—keeping the tooth moist, gentle handling, and immediate dental care—can significantly increase the chances of saving it. Preparedness can make a critical difference in preserving your smile.
