Having a tooth knocked out is alarming, but what you do in the first hour can decide whether the tooth can be saved. A knocked-out (avulsed) adult tooth is a genuine dental emergency, and acting quickly and correctly gives it the best possible chance of surviving. This guide walks you through exactly what to do, step by step, and how to reach an emergency dentist in Daventry fast.
Why the first hour matters
When an adult tooth is knocked out, the delicate cells on the root surface begin to die within minutes of being exposed to air. The sooner the tooth is placed back into its socket or kept in a suitable liquid, the better the chance it can be successfully reimplanted. Dentists often describe a “golden hour”: teeth reimplanted within about 60 minutes have a far higher survival rate. Speed and correct handling are everything.
Step by step: what to do in the first hour
- Find the tooth and pick it up by the crown. Hold the white chewing part, never the root, to protect the fragile cells that help it reattach.
- Do not scrub it. If the tooth is dirty, rinse it gently for a few seconds in milk or cool running water. Do not scrub, use soap, or dry it, and do not wrap it in tissue.
- Try to reinsert it. If you can, gently place the tooth back into its socket the right way round and hold it in place by biting softly on a clean cloth.
- If you cannot reinsert it, keep it moist. Store the tooth in a cup of milk, or hold it inside the cheek between the teeth and gum. Do not store it in water, which damages the root cells.
- Control any bleeding. Bite on clean gauze or a cloth over the socket to manage bleeding.
- Contact an emergency dentist immediately. Call ahead so they know a knocked-out tooth is on the way and can see you straight away.
Baby teeth are different
If a child knocks out a baby (milk) tooth, do not try to put it back. Reimplanting a baby tooth can damage the developing adult tooth underneath. Still contact a dentist for advice and to check for other injuries, but the tooth itself should not be reinserted.
The best ways to store a knocked-out tooth
If reinserting the tooth is not possible, the storage medium matters. In order of preference: back in the socket, then milk, then inside the cheek (for adults who will not swallow it), then saliva. Avoid tap water, as it causes the root cells to swell and die more quickly. Bring the tooth with you in its container.
What the dentist will do
At the appointment, the dentist will clean the area, reposition the tooth if it is viable, and usually splint it to the neighbouring teeth for a period of healing. They may take an x-ray and discuss follow-up care, including whether root canal treatment will be needed later. Even a delayed or uncertain case is worth showing to a dentist, as options may still exist.

Frequently asked questions
Can a knocked-out tooth be saved?
Often yes, especially if it is an adult tooth reimplanted within about an hour and kept moist in milk or saliva in the meantime. Handling it by the crown and seeing a dentist immediately gives the best chance.
Should I put a knocked-out tooth in water?
No. Water damages the delicate root cells. Store the tooth in milk, inside the cheek, or ideally back in its socket until you can see a dentist.
What if I cannot get to a dentist within an hour?
Still keep the tooth moist in milk and seek dental care as soon as possible. Reimplantation may still be attempted after an hour, so do not give up — contact a dentist for advice straight away.
