If you have severe swelling and/or severe bleeding, you should call 911 or go to the nearest hospital emergency room.

What do I do if a tooth gets knocked out?

Act quickly! The best chance for tooth survival is to provide treatment within 30 minutes of the injury.

Find the tooth, but do your best not to touch it—grab the tooth by the top or crown surface.

  • Replant the tooth immediately into its spot in your mouth, if possible.
  • Do not allow the tooth to dry out.
  • Place the tooth in COLD WHOLE MILK.
  • NEVER place the tooth in water.
  • Immediately go to your dentist or to the USC Urgent Care and Dental Trauma Center.
