A knocked-out permanent tooth is one of the few true dental emergencies where minutes genuinely matter. Acting quickly and correctly in the first 30 minutes gives a real chance of saving the tooth rather than needing an implant or bridge later.
Step 1: Find the tooth and handle it by the crown only
Pick the tooth up by the chewing surface (the crown), never by the root. The root surface contains delicate ligament fibers that are essential for the tooth to be successfully reimplanted, and touching them can damage the tooth's chances of survival.
Step 2: Rinse gently, don't scrub
If the tooth is dirty, rinse it briefly with milk or saline solution — plain water if nothing else is available, for no more than 10 seconds. Do not scrub it, use soap, or wrap it in a dry tissue, all of which can damage the root surface further.
Step 3: Try to reinsert it, if possible
If you can do so calmly, gently push the tooth back into its socket facing the correct direction and hold it in place by biting down softly on a clean cloth. A tooth reinserted within 5 minutes has the best chance of successfully reattaching. If reinserting isn't possible or safe, move to step 4 immediately.
Step 4: Keep it moist if it can't go back in
- Place the tooth in a cup of milk — the best readily available option, since its composition is gentle on the root surface
- If milk isn't available, use saliva (hold the tooth inside your cheek) or a saline solution
- Never let the tooth dry out, even briefly — dry time significantly reduces the chances of successful reimplantation
- Never store it in plain tap water, which can damage the root cells
Step 5: Get to a dentist immediately
This is a true emergency — call our office right away, even outside normal hours, and get to us or an emergency dental provider as fast as possible. The chances of successfully saving the tooth drop significantly after 60 minutes outside the mouth, so speed matters more than almost any other factor.
A note on baby teeth
Knocked-out baby teeth are handled differently — they generally should not be reinserted, since doing so can damage the developing permanent tooth underneath. Still call us promptly, but the urgency and approach differ from a permanent tooth.
For what to expect once you're in our chair, see our new patients page — but for this specific situation, call us immediately.
