Ask the Dentist: What Should I Do If My Child Knocks Out a Tooth?

By: Joseph Brier, DMD, FAGD, Dental Care of Lucas

It’s one of those moments every parent hopes to avoid, but accidents happen. Whether it’s a fall on the playground or a collision during sports, a knocked-out tooth can be scary for both you and your child. The good news is that knowing what to do in those first few minutes can make a big difference.

The first thing to determine is whether it’s a baby tooth or a permanent (adult) tooth.

If it’s a baby tooth, try not to panic. In most cases, baby teeth are not reimplanted. The best next step is to gently clean your child’s mouth if needed and contact your dentist for guidance. They’ll want to check the area to make sure there’s no damage to the surrounding teeth or developing adult tooth underneath.

If it’s a permanent tooth, time is critical. Acting quickly can sometimes save the tooth.

Start by carefully picking up the tooth by the crown (the chewing surface), not the root. If it’s dirty, gently rinse it with water, don’t scrub it or use soap. If possible, try to place the tooth back into the socket right away and have your child gently bite down on a clean cloth or gauze to hold it in place.

If you can’t reinsert the tooth, keep it moist. The best option is to place it in a container of milk. If milk isn’t available, you can have your child hold it in their mouth between the cheek and gums (if they’re old enough to do so safely), or place it in a tooth preservation solution if you have one on hand. Avoid letting the tooth dry out.

Then, call your dentist immediately. Ideally, a knocked-out permanent tooth should be evaluated and treated as soon as possible, ideally within 30-60 minutes for the best chance of saving it.

Even if you’re unsure whether the tooth is a baby or permanent tooth, it’s always best to call. Your dental team can help guide you through the situation and prepare for your arrival if needed.

While you can’t prevent every accident, wearing a mouthguard during sports and active play can significantly reduce the risk of dental injuries, especially for children with developing smiles.

Situations like this are never convenient, but being prepared can help you stay calm and act quickly. And in many cases, that quick action can make all the difference in protecting your child’s smile.
