Knocked Out Tooth Emergency

Critical steps to save a knocked out permanent tooth.

Act Quickly

A knocked-out permanent tooth is a dental emergency. With quick action, the tooth can often be saved. The chances of saving the tooth are highest if you can see a dentist within 30 minutes.

Immediate Steps

What to do right away:

  • Find the tooth and pick it up by the crown (white part), NEVER the root
  • If dirty, gently rinse with water—don't scrub or remove tissue
  • Try to reinsert the tooth in the socket (if possible)
  • If you can't reinsert, keep tooth moist in milk, saliva, or saline
  • Get to a dentist or emergency room immediately
  • Time is critical—best results within 30 minutes

What NOT to Do

Avoid these mistakes:

  • Don't touch the root
  • Don't let the tooth dry out
  • Don't wrap in tissue or cloth
  • Don't put in regular water for extended time
  • Don't scrub or use soap on the tooth
  • Don't delay—every minute counts

At the Dentist

The dentist will clean the tooth and socket, reposition the tooth, and splint it to adjacent teeth. Root canal treatment is often needed later. With proper care, many reimplanted teeth can last for years.

Baby Teeth

Don't try to reimplant a baby tooth—it can damage the developing permanent tooth underneath. Control bleeding with gauze and see a dentist to ensure no damage to permanent teeth.

Frequently Asked Questions

Can a knocked out tooth be saved?

Yes, if you act quickly. A tooth reimplanted within 30 minutes has a 90% chance of long-term survival. After 60 minutes, chances drop significantly. Keeping the tooth moist and getting to a dentist fast are crucial.

Why put the tooth in milk?

Milk has proteins and a pH that helps keep the tooth's root cells alive. It's better than water, which can cause root cells to swell and die. Milk can preserve the tooth for 30-60 minutes.

What if I can't find the tooth?

Still see a dentist or go to the ER. They'll need to check for injuries to your mouth, jaw, and remaining teeth. If the tooth was swallowed or lost, replacement options include implants, bridges, or partial dentures.
