If your child have a broken tooth, see your pediatric dentist as soon as possible. Your dentist can figure out if the break was caused by a cavity or trauma, and if the tooth's nerve is in danger. A damaged nerve usually will require nerve treatment.
Until you get to the dentist's office:
Have your child rinse mouth well with warm water.
Apply pressure with a piece of gauze on any bleeding areas for about 10 minutes or until the bleeding stops. If this doesn’t work, use a tea bag with pressure on the area to stop the bleeding.
Apply a cold pack to the cheek or lips over the broken tooth. This will help reduce swelling and relieve pain.
If you can't get to your dentist right away, cover the part of the tooth that is in your mouth with temporary dental cement. You can find this at a drugstore.
Take an over-the-counter pain reliever.
Seeing a dentist as soon as possible will decrease chance of complication later.
