A knocked-out permanent tooth requires immediate action. Protect the root, keep the tooth from drying out and get to an emergency dental provider as quickly as possible.
Handle the crown and keep the root safe
Pick the tooth up by the chewing surface. Avoid touching or scraping the root. If it is dirty, rinse briefly with milk or saline; do not use soap, scrub the tooth or wrap it in a dry tissue.
If it is safe to do so, place the tooth gently back into the socket. Otherwise keep it in milk or an appropriate tooth-preservation solution and bring it with you.
Do not reinsert a baby tooth
Reinserting a baby tooth can harm the developing permanent tooth. If there is any doubt about the tooth or the injury, seek professional advice immediately.
Children and adults with significant facial trauma may also need medical assessment for jaw, head or other injuries.
Travel with a plan, not a delay
Note the exact time of injury and call ahead while arranging the fastest safe transportation. Confirm that the destination knows you are coming for dental trauma.
Do not spend critical time trying home remedies or searching for a guaranteed outcome. The treating dentist will explain whether replantation or another approach is appropriate.
