Knocked-Out or Broken Tooth: First Aid
Written & medically reviewed by Dr. Rajat Shaikh, MDS — Pediatric & Preventive Dentistry · Last updated July 2026
If a permanent tooth is knocked out, act fast: hold it by the crown, gently rinse it, try to reinsert it or keep it in milk, and see a dentist within 30–60 minutes — quick action can save the tooth.
A knocked-out or broken tooth is a dental emergency where minutes matter. Stay calm and follow these steps.
What to do if a tooth is knocked out
- Pick the tooth up by the crown — never touch the root
- Gently rinse it with milk or clean water (don’t scrub)
- If you can, place it back in the socket and bite softly on a clean cloth
- If not, keep it in a cup of milk (or the person’s saliva) — not water
- Get to a dentist within 30–60 minutes
What to do for a broken or chipped tooth
- Rinse the mouth with warm water
- Save any broken pieces in milk or water
- Use a cold compress for swelling
- See a dentist as soon as possible
For children and baby teeth
Do not try to reinsert a knocked-out baby tooth — take your child to the dentist instead. For any child dental injury, see our pediatric team promptly.
Frequently asked questions
Can a knocked-out tooth be saved?
Often yes, if you act within about an hour and keep the tooth moist (ideally reinserted or in milk). The sooner you reach a dentist, the better the chance.
Why keep a tooth in milk?
Milk keeps the delicate root-surface cells alive far better than water, improving the chance the tooth can be successfully re-implanted.
