Knocked-out tooth

A knocked-out adult tooth can usually be saved by putting it back in place or in milk as soon as possible, before seeing a dentist.

What to do if a tooth has been knocked out

If it's an adult (permanent) tooth:

Hold it by the white bit that sticks out of the gum (the crown). Do not touch the root.

Lick it clean if it's dirty, or quickly rinse it in cold running water for no more than 10 seconds.

Try to put it back into the hole in the gum. If it does not go in easily:

If it goes back in, bite down gently on a clean cloth to hold the tooth in place.

Go to a dentist as soon as possible.

If it's a baby tooth:

Other ways to get help

Get an emergency dentist appointment

If you have a dentist, ask them for an emergency appointment.

If they're closed, their phone message may say what to do.

If you do not have a dentist, find a dentist near you and ask if you can have an emergency appointment.

What the dentist will do

If you put the tooth back in, the dentist will check it's in the right place and move it if they need to.

If you brought the tooth in milk or saliva, they'll clean it and put it back in.

They'll then fix the tooth to the teeth either side of it to hold it in place (splinting).

You'll probably need to go back after a couple of weeks to have the splint removed.

If you cannot find the tooth or the dentist is not able to save it, it can normally be replaced with a false tooth.

You may have to pay for your appointment and treatment.
