What should I do if a tooth is knocked out?
Direct answer
If an adult tooth is knocked out, act immediately. Hold the tooth by the crown, not the root. If it is dirty, rinse it gently with milk, saline or saliva. If possible, place it back in the socket without forcing it and seek dental care urgently. If it cannot be reinserted, keep it in milk or saliva and go to a dentist as soon as possible. Do not reinsert a baby tooth.
Why time matters
A knocked-out permanent tooth is one of the most time-sensitive dental emergencies. The cells on the root surface can be damaged if the tooth dries out or is handled incorrectly.
The chance of saving the tooth is better when it is managed quickly and stored correctly before professional treatment. Baby teeth should not be put back into the socket because this can damage the developing adult tooth.
What should you do immediately?
- Stay calm and find the tooth if possible.
- Hold the tooth by the white crown, not the root.
- If dirty, rinse gently with milk, saline or saliva. Do not scrub.
- Try to place an adult tooth back into the socket only if it goes in easily.
- If it cannot be reinserted, store it in milk or saliva.
- Seek urgent dental care immediately.
- Do not reinsert a baby tooth.

What happens at Gloss & Floss Dental Care®?
At Gloss & Floss Dental Care® in Stockholm, we assess the injury, check whether the tooth can be repositioned or stabilized and examine the surrounding teeth, gums and jaw. X-rays may be needed to check for root fractures, bone injury or damage to neighboring teeth.
Follow-up is important after dental trauma. Even if the tooth is replaced successfully, later checks may be needed because the nerve, root and surrounding tissues can change after the injury.
When should you seek care?
A knocked-out adult tooth should be handled as an urgent dental emergency. Seek care immediately, especially if there is bleeding, pain, jaw injury, a broken tooth fragment or trauma to the face.
Safety note: If there are signs of serious injury, heavy bleeding, loss of consciousness, breathing problems or major facial trauma, seek emergency medical care.
Frequently asked questions
Can a knocked-out adult tooth be saved?
Sometimes yes, especially if it is managed quickly, kept moist and treated urgently by a dentist.
Should I put a knocked-out tooth in water?
Milk or saliva is generally preferred if the tooth cannot be reinserted. Avoid letting the tooth dry out.
Can I put a baby tooth back in?
No. A baby tooth should not be reinserted because it may damage the permanent tooth developing underneath.
Do I still need care if the tooth was put back in?
Yes. The tooth needs professional assessment, stabilization and follow-up after trauma.
