What it is
A knocked-out tooth, which dentists call an avulsed tooth, is a tooth that has come completely out of its socket, often because of a fall, sports hit, accident or other injury. It's different from a loose or chipped tooth, though those also deserve a prompt dental exam.
Time matters because the tissues that hold a tooth in place are delicate. That's why dental offices often treat this as an urgent visit and may try to fit you in quickly. Whether a tooth can be put back depends on many factors that only a licensed dentist can judge after an exam.
Baby teeth and adult teeth are handled differently. A baby tooth is generally not put back in, but a child who has had a mouth injury should still be seen by a dentist. Ask the dentist's office what applies to your situation.
How it’s traditionally been approached
Commonly shared first-aid guidance includes staying calm, picking the tooth up by the crown (the chewing part) rather than the root, and avoiding scrubbing it or removing attached tissue. If it's dirty, a gentle rinse is often suggested.
Many dental offices have traditionally advised that an adult tooth be kept moist and not allowed to dry out. Some suggest gently placing it back in the socket if that's comfortable, while others suggest keeping it in milk or a tooth-preservation product made for this purpose. Don't force it, and call the dentist for guidance on the spot.
Afterward, a dentist usually examines the mouth, the tooth, the surrounding bone and neighboring teeth, and may take X-rays. Depending on the case, options discussed can include re-placing the tooth, stabilizing it, follow-up care, or, if it can't be saved, replacement choices. Only a licensed dentist decides what's appropriate.
How the right dentist may help
The right emergency dentist may help by assessing the injury quickly, making you comfortable and explaining your options in plain English. When you call, say that an adult tooth has been knocked out. The office can often give you instructions over the phone while you're on your way.
A visit generally starts with questions about what happened and your health history, then a gentle exam and imaging. Some injuries involve other care, such as an endodontist (root canal specialist) for the tooth's nerve, or an oral and maxillofacial surgeon for more complex jaw or facial injuries. If you feel anxious, tell the team. Dentists permitted by their state board may offer options such as sedation when appropriate.
Good questions to ask include: What are my options for this tooth? What follow-up visits might I need? What signs should make me call you again? Could you give me a written treatment plan and estimate? Costs vary by practice, location and case, and you should never feel shamed for asking about them.
The whole-person view
Mouth injuries are stressful. The body reacts with adrenaline and pain, and the mind may race with worry about appearance, cost or a past dental experience. Body, mind and stress all affect each other, so taking slow breaths and getting calm support can make the situation feel more manageable.
If an injury or dental fear stays with you afterward, you're not alone, and no approach is wrong. Somatic Experiences offers body-based support for calming the stress response, and Therapists.plus can connect you with talk therapy. Both are optional, and neither replaces urgent dental care.

Keep in mind
- Facial or neck swelling with fever, trouble breathing or swallowing, uncontrolled bleeding, or a serious face or jaw injury is a medical emergency: call 911 or go to the ER.
- A knocked-out adult tooth needs a dentist right away, so call an emergency dentist immediately. If you can't reach one, urgent care or an ER can help with the injury.
- Head injuries can accompany mouth injuries. If there was a blow to the head, confusion, vomiting or loss of consciousness, seek medical care right away.
- Licensed professionals should guide all care. If you're in emotional crisis, call or text 988.

Frequently asked questions
What should I do first if my tooth is knocked out?
Stay calm and call an emergency dentist right away, because an adult knocked-out tooth needs prompt dental care. Handle the tooth by the crown, avoid touching the root, and don't scrub it. The dental office can give you instructions for your situation.
How do you store a knocked-out tooth?
Commonly shared guidance is to keep the tooth moist and not let it dry out, often in milk or a tooth-preservation product, or gently back in the socket if that's comfortable. Don't wrap it in tissue or let it dry. Ask the dentist's office what they recommend when you call.
Can a knocked-out tooth be put back in?
Sometimes it can, but that's a decision for a licensed dentist after an exam. Many factors matter, including how the tooth was kept and how quickly you were seen. No one can promise an outcome, so get seen as soon as you can.
Should I go to the dentist or the ER for a knocked-out tooth?
Call a dentist first, since they can treat the tooth itself. Go to the ER or call 911 for facial or neck swelling with fever, trouble breathing or swallowing, uncontrolled bleeding, a serious face or jaw injury, or a head injury. If you can't reach a dentist, urgent medical care can help.
What if a child's baby tooth is knocked out?
Baby teeth are generally not put back in, but the child should still see a dentist to check the mouth and the other teeth. Call a pediatric dentist or your dentist for guidance. Bring a calm, reassuring attitude, since kids pick up on our worry.
How much does it cost to treat a knocked-out tooth?
Costs vary by practice, location and case, so there's no single answer. Ask the office for a written treatment plan and estimate, and ask about payment options. Don't delay an urgent call because of cost worries, since a dentist can talk through choices with you.
