🌿 Overview
A knocked-out (avulsed) tooth is a dental emergency. A permanent tooth has the best chance of being saved if it's put back in its socket — or kept moist — and you reach a dentist within about 30 to 60 minutes.
When a permanent tooth is knocked out, the delicate fibers that hold it in the socket are torn but can sometimes reattach if the tooth is replaced quickly and handled correctly. Time is everything — the longer the tooth is out and dry, the lower the chance of saving it.
Handle the tooth by the white crown, never the root; if it's dirty, rinse it briefly with milk or saline (not by scrubbing); and ideally slip it back into the socket and bite gently on a cloth. If you can't, keep it in milk and get to a dentist or emergency room immediately. Baby teeth are not replaced — but still see a dentist.
Common signs
- A whole tooth out of its socket after a blow or fall
- Bleeding from the empty socket
- Pain and swelling

Keep the knocked-out tooth and the mouth moist — but milk or saline is best for storing the tooth itself en route to care.100573

🍽️ Eating to help
Food is one of the gentlest medicines — small, steady changes help most.
Favor these
- Soft foods after treatment while the area heals
Go easy on
- Hard, crunchy foods on the injured tooth
After emergency care, follow the dentist's eating guidance.
⚖️ Good to know
- Never let the tooth dry out or store it in plain water for long — milk or saline is far better.
- Don't scrub the root or wrap the tooth in tissue.
- Baby teeth are not re-implanted, but the child should still see a dentist.
🩺 When to see a doctor
- Immediately — this is an emergency; see a dentist or go to the ER within 30–60 minutes
- Any facial injury with a knocked-out or loosened tooth
- Heavy bleeding, or a blow hard enough to cause dizziness or confusion (seek urgent care)
