Knocked-Out Tooth? Do These 5 Things in the First Hour

A knocked‑out permanent tooth is one of the very few dental emergencies where minutes genuinely decide the outcome. Act quickly and correctly, and there's a real chance your dentist can put the tooth back and save it for good. Hesitate, and that window closes fast. Here's exactly what to do in the critical first hour — and what to avoid.

Can a knocked-out tooth really be saved?

Often, yes — but the clock is the deciding factor. A permanent tooth has the best chance of surviving when it's placed back in its socket within about 15 minutes, and a good chance for up to 30 to 60 minutes if it's kept moist the right way. After roughly an hour out of the mouth and dry, the delicate cells on the root begin to die and re‑implanting becomes far less predictable. That's why everything below comes down to two things: speed, and keeping the tooth alive on the way to us.

The 5 things to do in the first hour

1. Pick the tooth up by the crown — the white chewing part you normally see. Never touch or handle the root; the living cells on it are what allow the tooth to reattach.
2. Rinse it gently, and only if it's dirty. A few seconds under milk or sterile saline is plenty. Don't scrub it, don't scrape off any attached tissue, and don't wrap it in a cloth or tissue.
3. Try to put it back in the socket. This is the single best place to store a knocked‑out tooth. Ease it in the right way around and bite down gently on clean gauze or a cloth to hold it there.
4. If you can't reinsert it, keep it moist in milk. Submerge the tooth in a small container of milk, or tuck it inside your cheek. Milk's makeup protects the root cells — plain water actively damages them, so never use it.
5. Get to a dentist immediately — ideally within 30 to 60 minutes. Call on the way so we're ready the moment you walk in.

What not to do

Just as important as the steps above is what to avoid, because a few natural instincts do real harm. Don't let the tooth dry out — a dry root is the main reason a knocked‑out tooth can't be saved. Don't scrub the root or pick off the soft tissue clinging to it, and don't wrap the tooth in a napkin, which wicks away the moisture it needs. Never store it in tap water; the chlorine and missing minerals kill the root cells within minutes. And whatever you do, don't take a wait‑and‑see approach — with an avulsed tooth, time is the one thing you can't get back.

What about a child's baby tooth?

The rules flip for baby teeth. A knocked‑out baby tooth should not be put back in, because forcing it into the socket can damage the permanent tooth developing underneath. Still call us right away — we'll check the area, watch for any fragments, and make sure the gum and the tooth coming in behind it are healthy.
