Patient being treated in the dental chair after a knocked-out tooth

The short answer

Pick the tooth up by the crown, never the root. If it is dirty, rinse it for a couple of seconds in milk or saline — not water, and never scrub it. If you can, push it gently back into the socket and bite on a clean cloth to hold it. If you cannot, keep it in milk, or tucked inside the cheek. Then get to a dentist immediately. The first hour is what decides whether the tooth survives, and every ten minutes counts.

Do this now

  • Hold it by the crown — the white chewing part. The root surface carries the living cells that let it reattach, and touching them destroys them.
  • Do not scrub, wipe or disinfect it. A two-second rinse in milk or saline is the most it should get.
  • Put it back in the socket if you can manage it, the right way round, and bite gently on a clean cloth.
  • If it will not go back, put it in a cup of milk. Milk is the best thing most people have to hand.
  • No milk? Tuck it inside your cheek, or use saline. Plain water is the worst option — it kills the cells fastest.
  • Call us and set off. Do not wait to see whether it settles.

Baby teeth are different

A knocked-out baby tooth is not put back — replanting it can damage the adult tooth forming above it. Keep the child calm, control the bleeding with gentle pressure on a clean cloth, and call us so we can check the socket and the neighbouring teeth. Bring the tooth if you have it.

Go to the emergency room, not a dentist, if

  • Trouble breathing or swallowing.
  • Swelling spreading toward your eye, under your jaw, or down your neck.
  • Bleeding that will not stop after 15 minutes of firm pressure.
  • A blow to the head with confusion, vomiting or any loss of consciousness.
  • A fever over 101°F together with facial swelling.

If any of these apply, go to the nearest emergency room or call 911. That is a hospital problem, not a dental one.

Questions people ask

How long can a tooth survive out of the mouth?

The best chance is within the first 30 to 60 minutes. After about an hour dry, the cells on the root surface are usually gone and the odds drop sharply. Kept in milk, the window stretches — which is exactly why the milk matters.

Can I put it in water?

Avoid it. Plain water makes the root cells swell and burst faster than anything else you could choose. Milk, saline, or your own cheek are all far better.

What if the tooth is chipped rather than out?

Keep the fragment in milk or a clean container and bring it — a piece can sometimes be bonded straight back on. Cover any sharp edge with sugar-free gum so it does not cut your tongue on the way.
