Yes, a knocked-out permanent tooth can often be saved if you act quickly. The best results usually come when the tooth is placed back into its socket or stored properly and a dentist reimplants it within about 30 to 60 minutes, which is an estimate. The longer the tooth stays dry and out of the mouth, the lower the chance of success.

Why this matters

This page is educational and is not medical advice, a diagnosis, or a treatment plan. For a knocked-out tooth, see a dentist right away.

The save-my-tooth steps, one at a time.
Quick answer
A knocked-out adult tooth can often be saved if you act fast. Pick it up by the crown, not the root. If it is dirty, rinse it gently with milk or saline. Try to place it back in the socket and bite on clean gauze, or keep it in milk or your cheek. Then see a dentist right away. The best window is about the first 30 to 60 minutes. Do not reinsert a child's baby tooth.
The steps at a glance
How to save a knocked-out tooth.
Here are the same steps in one place, so you can scan or share them. Sooner is better, ideally within about 30 to 60 minutes.
- Pick the tooth up by the crownFind the tooth and pick it up by the white crown, never touching the root surface.
- Rinse it gently if dirtyIf the tooth is dirty, rinse it briefly with milk or saline without scrubbing, wiping, or removing any attached tissue.
- Try to place it back in the socketFor a permanent tooth, gently slide it back in facing the correct way, then bite softly on clean gauze to hold it.
- If you cannot reinsert it, keep it moistStore the tooth in cold milk or in your own saliva, and avoid plain water so the root cells stay protected.
- Control bleeding and ease discomfortBite gently on clean gauze to slow any bleeding, and use a cold compress on the outside of the face for swelling.
- See a dentist immediatelyGet to a dentist or emergency dental service as fast as possible, bringing the tooth with you.

Why time matters
Dry time is the single biggest factor.
The root of the tooth is covered in living cells that need to stay moist. Once the tooth is out of the mouth and dry, those cells begin to die quickly. That is why keeping the tooth wet, in milk or saliva, matters as much as speed. A tooth kept moist does far better than one left dry, even at the same total time.
A general guide to how the odds shift with dry time, not exact figures. Even after an hour, bring the tooth and see a dentist, since they can still help and may be able to save it.
Adult vs baby tooth
A baby tooth is handled differently.
For a permanent adult tooth, the goal is to get it back in place as fast as possible. For a child's baby tooth, the rule is the opposite. Do not try to put a knocked-out baby tooth back in, because that can harm the adult tooth forming underneath. Instead, have the child bite gently on clean gauze to slow any bleeding, use a cold compress on the cheek for comfort, and see a dentist promptly so they can check the area. If you are not sure whether a tooth is a baby tooth or a permanent tooth, do not force anything and let the dentist decide.
At the dentist
What happens once you arrive.
You have done the important first minutes. From here, the dentist takes over and works to settle the tooth back in and keep it healthy.
Clean and reimplant
The dentist cleans the tooth and socket and places the tooth back in the correct position if it is not already in.
Splint it in place
A flexible splint bonds the tooth to its neighbors to hold it steady, usually for about 1 to 2 weeks, longer if it was dry for a while.
Check for infection and tetanus
Since this is a trauma injury, the dentist checks tetanus status and may prescribe medicine to protect against infection.
Plan a root canal and follow up
A root canal is needed in most cases because the nerve usually does not survive, then the dentist monitors healing over time.
A knocked-out tooth is usually a multi-step repair: the emergency visit and splint first, then a root canal, and often a crown later. See how a root canal is covered.
Cost and coverage
How coverage fits a knocked-out tooth.
The emergency exam and X-ray are usually covered at or near 100 percent, so getting diagnosed costs little with a plan. The repair is where the cost sits, since it often runs from an emergency visit and splint to a root canal, often estimated around 700 to 1,600 dollars, and sometimes a crown. A plan that pays toward major work shares part of that cost. If treatment cannot wait, a plan with no waiting period helps from day one. See coverage that can start fast.
If the tooth cannot be saved, that is more common than you might think, and it is not the end of the road. There are good replacement options, such as an implant or a bridge that looks and works like a natural tooth. A dentist will talk you through what fits you best, and you do not have to decide any of it tonight. Estimate your treatment cost.
Questions
Knocked-out tooth questions.
Time is critical. As a general estimate, the best chance of saving a permanent tooth is within about 30 to 60 minutes of it being knocked out. Even if more time has passed, you should still bring the tooth and see a dentist right away, because they can assess your specific situation.
For a permanent adult tooth, you can gently try to place it back into the socket if it is clean and you feel comfortable doing so. Hold it by the crown, not the root, and bite down softly on clean gauze to hold it in place. If you cannot reinsert it, store it in milk or saliva and see a dentist immediately. Do not try to reinsert a knocked-out baby tooth.
Keep the tooth moist at all times. The best options are cold milk or your own saliva, for example by holding it inside your cheek if you will not swallow it. Avoid storing the tooth in plain water, because water can damage the cells on the root surface that help it reattach.
First, work out whether it is a baby tooth or a permanent tooth. Do not try to reinsert a knocked-out baby tooth, because that can harm the developing permanent tooth underneath. For any knocked-out tooth in a child, keep the area calm, control bleeding with gentle pressure, save the tooth in milk, and see a dentist or seek emergency care promptly.
Yes, a knocked-out permanent tooth is a dental emergency even if there is little or no bleeding. The amount of blood does not tell you how successful reimplantation will be, since timing and proper handling matter most. Save the tooth, keep it moist, and see a dentist right away.
