What Happens If Your Child Swallows a Baby Tooth?

Take a breath, if your child just swallowed a baby tooth, it’s almost always completely harmless, and the tooth passes on its own within a few days. This guide walks you through exactly what happens next: how a swallowed tooth moves through the body, the rare moments that call for a doctor, 811, or 911, and even what to tell the Tooth Fairy when there’s no tooth to tuck under the pillow.

Your Child Swallowed a Baby Tooth: Should You Be Worried?

Short answer: almost certainly not. A baby tooth is tiny and smooth, and once it’s swallowed it nearly always travels through the digestive system and comes out naturally, no different from a small piece of food. If your child is breathing normally, talking, and comfortable, they’re fine.

The one thing worth ruling out is whether the tooth went down the food pipe (swallowed, harmless) or into the airway (inhaled, the rare situation that needs attention). Here’s how to tell the difference.

What Happens to a Swallowed Baby Tooth?

Once it’s down, the tooth goes through the esophagus into the stomach, then through the intestines, and finally out in the stool, usually with no discomfort along the way. Your child’s body treats it like any other small, indigestible object.

Will the tooth come out in their poop? Usually, yes. You don’t have to go hunting for it, but you can keep an eye out over the next few days if it puts your mind at ease.

How long will it take to pass? Typically one to three days, and up to about a week. There’s no need to watch the clock.

Do you need to find the tooth? Nope, recovering it isn’t necessary for your child’s health. And if you’re already wondering about the Tooth Fairy, don’t worry, there’s an easy fix further down.

Can a Child Choke on a Baby Tooth?

This is the one part worth your attention for a moment. There’s a big difference between swallowing a tooth (it heads down the food pipe toward the stomach, harmless) and inhaling it (it goes into the airway, an emergency). Inhaling a tooth is uncommon, but it’s the reason to stay alert right after it happens.

Get help right away if you notice any signs the tooth may have gone into the airway:

• Persistent coughing that won’t settle
• Wheezing or noisy, laboured breathing
• Trouble breathing, or chest pain
• Choking: can’t breathe, talk, or cry, or the lips turn blue

If your child is actively choking and can’t breathe, call 911 and start choking first aid immediately. But if they coughed once, bounced back quickly, and are breathing and eating normally again, the tooth almost certainly went down the right pipe.

When Should You Get Medical Help?

Most of the time, all your child needs is a calm eye on them. Here’s how to read the situation.

You can simply watch at home if your child is breathing normally, has no pain, and is eating and drinking as usual. Just carry on and let the tooth pass.

Call your doctor or dentist if your child develops belly pain, vomiting, blood in the stool, or refuses to eat, or if the tooth came out because of an injury (more on that next).

Call 811 if you’re unsure. It connects you with a registered nurse, 24/7 and free. It’s the perfect in-between option when it isn’t an emergency but you’d like a health professional’s reassurance before deciding what to do.

Call 911 if your child is choking, struggling to breathe, has blue lips, severe chest pain, or collapses. The airway is the real emergency, a tooth that’s safely in the stomach is not.

What If the Tooth Was Knocked Out in an Accident?

A tooth swallowed after a fall or a knock is a different story, because there may be other injuries. Check your child’s mouth for bleeding, cuts, loose fragments, or a broken tooth, and make sure nothing went into the airway.

If a permanent (adult) tooth was knocked out, that’s a dental emergency, see a dentist immediately, since timing matters for saving it. Baby teeth usually aren’t put back in, but it’s still worth having a dentist check for damage to the gums or to the adult tooth developing underneath.

Should You Pull a Very Loose Baby Tooth?

Your best move is to let a loose baby tooth come out on its own. Gentle wiggling is fine, but forcing one before it’s ready can cause pain, bleeding, and infection. Nature has good timing here.

Eating with a loose tooth is perfectly safe, offer softer foods if it’s uncomfortable, and if your child happens to swallow it mid-bite, see the section above (it’ll pass harmlessly). Sleeping with a very loose tooth is fine too. If it falls out overnight and gets swallowed in their sleep, there’s nothing to worry about.

What If Your Child Is Scared of Swallowing Another Tooth?

A little worry afterward is completely normal. Reassure your child that it didn’t hurt them and that their body knew exactly what to do. A few things that help: eat sitting up and unhurried, tell a grown-up whenever a tooth feels wobbly, and keep the mood light, losing teeth is a sign of growing up, not something to fear. Framing it as an exciting milestone does far more good than a list of warnings.

What Do You Tell the Tooth Fairy?

Here’s the reassuring part: the Tooth Fairy cares about the milestone, not the tooth itself.

Does she still come without the tooth? Absolutely. A missing tooth doesn’t disqualify anyone from a visit.

Can your child leave a note instead? This is the perfect fix. Have your child write or draw a quick note explaining what happened, plenty of families say the Tooth Fairy loves these little notes even more than the tooth.

What does she usually leave? It varies from family to family, but a coin or a couple of dollars is common. The note can become part of the fun and keep the magic alive.

Frequently Asked Questions

Can stomach acid dissolve a swallowed tooth? Not really, but it doesn’t need to. The tooth is small and smooth enough to pass through whole.

Can a swallowed tooth get stuck? It’s extremely rare for a tiny baby tooth; it almost always passes on its own. Seek care only if your child develops belly pain or vomiting.

Can a child swallow a tooth while sleeping? Yes, and it’s harmless if it’s swallowed. The only concern would be if it were inhaled, which is rare.

What if your child swallowed a tooth while eating? Very common, it just goes down with the food and passes normally.

What if you can’t tell whether they swallowed or inhaled it? Watch their breathing. Normal, comfortable breathing means it was swallowed. Coughing, wheezing, or trouble breathing means you should get help (call 811, or 911 if it’s severe).

Do swallowed teeth always show up in the stool? Usually, though you may not spot it, and that’s okay. Not finding it doesn’t mean anything’s wrong.

Should you call the dentist if you can’t find the tooth? Not for health reasons. A checkup is worth booking if the tooth came out from an injury or your child has any pain.

Can the Tooth Fairy still come if the tooth was swallowed? Of course, a little note under the pillow works perfectly.
