Tooth Injury


  • Injury to a tooth

Types of Tooth Injuries

  • Loosened tooth - may bleed a little from the gums. Usually tightens up on its own.
  • Displaced tooth (usually pushed inward)
  • Chipped or fractured tooth
  • Avulsed (knocked out) tooth - a dental emergency for permanent teeth

First Aid Advice for Knocked-Out Permanent Tooth

  • To save the tooth, it must be reimplanted as soon as possible (2 hours is the outer limit for survival). Right away is best. If more than 30 minutes away from dental or medical care, replace the tooth in the socket before coming in. Use the following technique:
  • Rinse off the tooth with saliva or water (do not scrub it). 
  • Replace it in the socket facing the correct way. 
  • Press down on the tooth with your thumb until the crown is level with the adjacent tooth.
  • Have your child bite down on a wad of cloth to stabilize the tooth until you can reach your dentist.
  • Note: Baby teeth can't be re-implanted.

Transporting a Knocked-Out Permanent Tooth

  • If unable to put the tooth back in its socket, follow these instructions:
  • It is very important to keep the tooth moist. Do not let it dry out.
  • Transport the tooth in milk or saliva (Milk is best per American Dental Association 2003)
  • MILK TRANSPORT OPTION 1 (best): Place tooth in a small plastic bag with some milk. Put the plastic bag in a cup of ice.
  • MILK TRANSPORT OPTION 2: Place tooth in a cup of cold milk.
  • SALIVA TRANSPORT OPTION 1: Put the tooth inside the child's mouth. (Be careful not to swallow it) (EXCEPTION: Age less than 12 years old)
  • SALIVA TRANSPORT OPTION 2: Put the tooth in a cup and keep tooth moist with child's saliva (spit).

Call Your Dentist Within 24 Hours (between 9 am and 4 pm) If

Parent Care at Home If

  • Minor tooth injury and you don't think your child needs to be seen


  1. Local Cold: For pain, apply a piece of ice or a popsicle to the injured gum area for 20 minutes.
  2. Pain Medicine: If it still hurts, give acetaminophen (e.g., Tylenol) or ibuprofen.
  3. Soft Diet: For any loose teeth, offer a soft diet for 3 days. By then, it should be tightened up.
  4. Call Your Dentist If:
    • Pain becomes severe
    • Tooth becomes sensitive to hot or cold fluids
    • Tooth becomes a darker color
    • Your child becomes worse

And remember, contact your doctor if your child develops any of the "Call Your Doctor" symptoms.
