First Aid for a Knocked Out Tooth

knocked out tooth toronto dentist

Falling down on your face or getting hit in the face can knock out a tooth (tooth avulsion). This type of tooth injury is serious. A permanent tooth can sometimes be put back into its socket. The best results occur if a dentist puts the tooth back in the socket within the first hour or sooner. Chances of successful re-implantation are unlikely after 2 hours.

If the knocked out tooth is a baby tooth

  1. Do not reinsert a knocked out primary tooth. This is because the re-implantation can cause problems with later development of the adult tooth.
  2. Wear medical gloves if available. If gloves are not available, wash your hands with soap and water or use hand sanitizer.
  3. Position the child leaning over in the face-forward direction so that bleeding does not cause choking.
  4. Control any bleeding. Start by locating clean medical or dental gauze (if available), or folding clean paper towel. Wet the gauze or paper towel with room temperature water. Then apply firm finger pressure with the gauze or paper towel against the tooth socket until bleeding stops. If possible, ask your child to bite down on the gauze or paper towel.
  5. Seek dental care immediately.

If the avulsed tooth is an adult tooth

  1. Wear medical gloves if available. If gloves are not available, wash your hands with soap and water or use hand sanitizer.
  2. Position the patient leaning over in the face-forward direction so that bleeding does not cause choking.
  3. Control any bleeding. Start by locating clean medical or dental gauze (if available), or folding a clean paper towel. Wet the gauze or paper towel with room temperature water. Then apply firm finger pressure with the gauze or paper towel against the tooth socket until bleeding stops. If possible, ask the patient to bite down on the gauze or paper towel.
  4. Try to find the tooth. If you find the tooth, do not handle it by its roots. Instead, handle the tooth by the tooth crown (the normally visible part of the tooth in the mouth). If the tooth is dirty, gently rinse it with room temperature water. Do not scrub or use antiseptic on the tooth.
  5. Reinsert the tooth (if it is a permanent tooth) into its correct position. Do not reinsert a baby tooth. Use finger pressure or bite down on gauze or paper towel to stabilize the tooth until you are able to see the dentist.
  6. If you cannot reinsert the tooth, keep the tooth moist by transporting it in cold milk or the patient’s saliva. Alternatively, wrap the tooth in a cloth wet with saliva. Do not put the tooth in tap water, salt water, alcohol, or mouthwash.
  7. Seek dental care immediately. For the best outcome, the patient should see the dentist within 1 hour of the incident or sooner.

Do not delay if you knocked out your tooth. Arrange to see the dentist immediately

When re-implanted and fixated within the first hour of tooth avulsion, there is a higher chance that the tooth will re-integrate and can be saved. Delaying dental treatment could result in re-implantation failure, leaving the dentist no choice but to remove the tooth, as well as more expensive tooth replacement treatment.
