Knocked-Out Tooth

A knocked-out permanent tooth is the one dental emergency where minutes genuinely decide the outcome. Reimplanted quickly, many teeth can be saved; after an hour dry, the odds fall steeply.

The protocol

Pick the tooth up by the crown — never the root. If dirty, rinse gently for a few seconds with milk or saline; don't scrub, and don't wrap it in tissue. Best move: push it back into the socket right away and bite gently on gauze or cloth to hold it. If you can't, transport it in cold milk (or saline, or tucked in the cheek of an adult patient) and get to a dentist immediately — call ahead so they're ready.

Baby teeth are different

Knocked-out baby teeth are NOT reimplanted — forcing one back can damage the adult tooth forming underneath. Still see a pediatric dentist promptly to check for other injury.
