Toddlers learning to walk and active school-age kids often bump their mouths, and the front teeth usually take the hit. What to do depends first on whether the tooth is a baby tooth or a permanent one.

Why Front Teeth Get Injured

Front teeth sit at the leading edge of the face, so they are the first to meet the floor, a table corner or a playmate’s head. Young children are still developing balance, and older children often injure teeth while biking, scootering or playing sports.

Baby Teeth vs. Permanent Teeth

According to the AAP, a knocked-out baby tooth generally does not need to be replaced, and children age 6 or younger most likely lost a baby tooth. Pushing it back in can disturb the developing permanent tooth underneath, but it is still sensible to have a dentist check for gum injury or retained fragments. A knocked-out permanent tooth (usually after about age 6-7) is a dental emergency where time matters. The AAP notes the best chance of saving it is reinsertion within about 15 minutes, though some teeth can still be saved within the first hour if you act quickly.

What to Do at Home

  • Calm the child and check for a head injury first. Loss of consciousness, vomiting or confusion means the emergency room comes before the tooth.
  • Pick up a permanent tooth by the crown, not the root. If dirty, rinse gently with milk or saline, without scrubbing.
  • If possible, put it back into the socket right away and have the child bite on gauze. If that is not possible, keep the tooth in milk or saline and head to a dentist or emergency room. Do not wrap it in tissue or let it dry.
  • For bleeding, have the child bite on clean gauze, and hold a cold pack wrapped in cloth against the cheek for swelling. If bleeding does not slow, get care promptly.
  • A loose tooth should not be wiggled; offer soft foods and see a dentist.

When heading to the dentist, jot down the time of the injury and how it happened, and note whether tetanus shots are up to date. In the car, an adult should watch the child so the tooth is not swallowed, and a container with a tight lid keeps milk from spilling. If a young child cannot cooperate, do not force the tooth back in; storing it in milk or saline for the trip is the safer option.

Common Misunderstandings

  • “It’s only a baby tooth” can lead to skipping the visit, yet a hard blow can affect the permanent tooth bud.
  • Soaking a knocked-out tooth in tap water or scrubbing it does not help.
  • A tooth that looks fine but slowly turns gray or dark can signal nerve damage and needs follow-up.

When to Seek Care

A knocked-out or broken permanent tooth calls for a dentist or emergency room right away. Go to the emergency room if bleeding will not stop, a lip or gum is deeply cut, the jaw seems out of place, or a head injury is possible. If a tooth fragment cannot be found, ask the doctor about the chance it was swallowed or embedded in the lip.
