The first thing to remember is to stay calm. Injuries to the mouth, face and teeth happen frequently in children. Remaining calm and taking prompt action will help minimize the damaging effects of the injury, and lessen your child's discomfort.
Second, assess whether or not you child's injury involved hitting the head causing them to lose consciousness even for a brief moment. If this is the case, your child should see a physician immediately. Worry about the mouth and teeth later.
Third, try to stop any bleeding with a clean washcloth or gauze. As you do this, check for broken teeth and/or missing teeth. If there are missing teeth, look for them.
Gently clean or rinse dirt from the area around the break. Place a cold compress on the face in the area of the broken tooth to minimize lip or facial swelling. If the fracture is more than one-half of the tooth, see the dentist immediately.
Knocked Out Tooth:
For permanent teeth - Find the tooth. Handle the tooth by the crown, not root. If the tooth is dirty, gently rinse it in cold water, but DO NOT scrub or handle the root unnecessarily. Try to replace the tooth into the socket. Have the child hold the tooth in place by closing on a gauze pad or washcloth. If it is not possible to replace the tooth, place the tooth in a cup of milk, or if this is not available, cool water. Go to the dentist immediately. Time is important for saving the tooth, less than 30 minutes is the best.
For primary (baby) teeth - Teeth are not re-implanted. The tooth fairy will be at work prematurely.
Bitten Tongue or Lip or cheek:
If there is bleeding apply gentle pressure with a clean cloth or gauze. Apply an ice compress to the injured area. If bleeding does not stop, go to a hospital emergency room.
Objects Caught between the Teeth:
Try to remove the object with dental floss. You may tie one or two small knots in the floss to help remove the debris. Do not use a sharp metal object. If you cannot remove it, go to the dentist.
Bleeding After a Baby Tooth Falls Out:
Fold a gauze pad or clean washcloth over the bleeding area. Keep it in place for 15 minutes, then repeat as necessary.
