Tooth Knocked Out or Traumatic Injury: Emergency Management and Care
Summary
A knocked-out tooth is a dental emergency that requires quick action to save the tooth. According to the American Dental Association (ADA) 2024 guidelines, immediate care within 30 minutes can increase the chances of successful re-implantation. This handout provides clear instructions on what to do and what to avoid if you or someone else loses a tooth due to an accident.
What Is This & Why It Matters
When a tooth is knocked out, it means it has been completely displaced from its socket in your mouth. This can happen due to an accident, sports injury, or other trauma. Acting quickly is essential because the cells on the root surface of the tooth start dying once the tooth is out of its natural environment. Prompt care can help save your tooth and reduce complications.
What You Should Do
- Pick up the tooth by its crown (the chewing surface), not the root.
- Gently rinse the tooth with milk or saline solution; never scrub it.
- If possible, place the tooth back into its socket in the mouth.
- If unable to reinsert, keep it moist by placing it under your tongue or in milk.
- Call an emergency dentist immediately for urgent care.
- Head to the nearest emergency room if a dentist is unavailable.
What You Should NOT Do
- Do not touch or scrub the root of the tooth.
- Avoid using tap water to rinse off the tooth.
- Don't delay seeking professional dental help.
- Do not store the tooth in dry tissue or cloth.
- Avoid handling the tooth more than necessary.
- Do not panic; stay calm and act quickly.
Symptoms: Normal vs Warning Signs
