Knocked Out Tooth First Aid – What NOT to do after a tooth is knocked out
When dealing with a knocked out tooth first aid situation, certain actions can make the injury worse. Avoid these common mistakes to protect the tooth and your overall health.
Do NOT
- Do not touch the root of the tooth. Handling the root can damage the cells needed for successful reimplantation.
- Do not scrub or clean the tooth with soap, chemicals, or alcohol. This can harm the tooth’s surface and reduce the chance of saving it.
- Do not try to force the tooth back into the socket yourself if you are unsure or uncomfortable. Incorrect placement can cause further injury.
- Do not store the tooth in water. Water can damage the root cells. Instead, keep it moist in milk, saliva, or a tooth preservation kit if available.
- Do not delay seeking professional care. Time is critical for saving a knocked out tooth. Aim to reach a dentist or emergency department within 30 minutes.
- Do not ignore severe bleeding, swelling, or signs of shock. If these occur, call 911 or go to the nearest emergency department immediately.
Following these guidelines helps improve the chances of saving the tooth and prevents complications. Always prioritise safety and seek urgent care when needed. See also: [Emergency dental care]
