01In brief
Tooth knocked out: what should I do?
Very urgent: every minute counts
A permanent tooth knocked out of the mouth is an immediate emergency: it has a much better chance of being saved if it is put back quickly, ideally within minutes and no later than one hour. Hold it by the crown (the white part) without touching the root, rinse it for a few seconds if it is dirty, put it back in its socket if you can or keep it in milk, and call the Go Dentiste clinic in Valleyfield right away at 514-533-3368. A baby tooth is never put back in.

04At the Valleyfield clinic
How a knocked-out tooth is put back in place
The dentist cleans the area, repositions the tooth if needed, checks its position with an X-ray and stabilizes it with a flexible splint bonded to the neighbouring teeth, usually for about two weeks.
Depending on how long the tooth was out of the mouth and the person’s age, a root canal may be needed in the following weeks. Check-ups are planned over several months to monitor healing.

06FAQ
Frequently asked questions: knocked-out tooth in Valleyfield
How much time do I have to save a knocked-out tooth?
As little as possible. A tooth put back within minutes has the best chance of reattaching. After an hour out of the mouth, especially if it has dried out, the chances drop sharply.
What should I carry the tooth in?
In milk, ideally. Otherwise, in the mouth against the cheek (conscious adult only) or in a small container with a little saliva. Avoid tap water and never let it dry out.
Should a baby tooth be put back in?
No. A baby tooth is not put back in, because this can damage the permanent tooth forming underneath. Still have the child examined quickly.
Will the replanted tooth last?
It depends on how long it was out of the mouth, how it was kept and the person’s age. The dentist provides follow-up and explains your options if the tooth does not reattach.
