My Child Swallowed Their Tooth. What Now?

A loose tooth comes out during an apple, or a sandwich, or a laugh, and it goes down before anybody can stop it. There are two separate questions here and it helps to keep them apart: whether your child is all right, and what the Tooth Fairy is supposed to do now. The first one is usually settled in a minute, and the second one is easier than it looks.

First, the part that actually matters

The question to answer is not really “is a tooth dangerous?” It is whether the tooth went down the food pipe or into the airway. Those are two different events, and a child tells you which one happened almost immediately.

The American Academy of Pediatrics publishes plain guidance for a swallowed object, and its general line is reassuring: most small, smooth or blunt objects pass without problems into the stomach.¹ Its own advice is to call the doctor if the object has not passed after three days, and to call 911 immediately for trouble breathing, for stridor — the harsh sound on breathing in — or for wheezing.¹

That is the whole triage, and it is worth reading twice, because it means the alarming case announces itself. A child who is talking, breathing easily and asking whether the Tooth Fairy still comes is a child who swallowed it. Call your own pediatrician if anything about it worries you; that is what they are for, and nobody has ever minded the question.

Why this happens so often

It is not carelessness. By the time a baby tooth is loose there is genuinely very little holding it in. The permanent tooth coming up underneath causes the root of the baby tooth to be reabsorbed, so what is left is held by a small amount of tissue and not much else.²

The first ones usually go at about age six, starting with the incisors — the middle teeth at the front.² Those are exactly the teeth that meet an apple first, which is why so many of these stories involve fruit, and why it will probably happen at least once in your house no matter how careful anybody is.

What to say in the moment

Children read your face before they hear your words. If you go pale and start asking urgent questions, a six-year-old concludes that they have done something serious, and you spend the next hour undoing that rather than dealing with the tooth.

So: check they are breathing comfortably, ask them to take a drink of water and tell you if it goes down normally, and then treat it as a funny thing that happened. It is a funny thing that happened. In a year it will be the version of the story they tell.

The Tooth Fairy does not need the tooth

This is the part parents quietly worry about, and it has a simple answer: nothing in the tradition requires the object. What a child is actually trading is the news, and the news travels fine without the tooth.

So write the note. A child who has swallowed a tooth and writes the Tooth Fairy a line about it is not a child who has lost anything — they have gained a better story than the pillow usually gets. Three lines under the pillow is plenty:

• Which tooth it was, and where they were standing.
• What they were eating, in as much detail as they want to give.
• A short apology, if they feel one is owed. Most of them do, and it is oddly good for them to write it.

What she writes back

A reply is what turns an accident into a keepsake. It does not need to be long, and the best ones are not: she has heard about the apple, she is not remotely cross, and she would like to know how the gap feels.

If you want to hand that over rather than write it at eleven at night, the Tooth Fairy will write it — you give her the details and she does the rest. There is also a certificate for the occasion, which sounds silly until you watch a six-year-old read an official-looking document about their own tooth.

Either way, write down where the tooth actually went. The lost tooth chart has a line for every tooth and a space for how it came out, and “swallowed it with an apple at Grandma’s” is by some distance the best entry anybody ever fills in.

If it goes wrong twice

Occasionally a swallowed tooth arrives on the same night you had also forgotten to do the Tooth Fairy at all, which is a particular kind of morning. There is a way out of that one too, and it is the same principle: one short explanation, delivered calmly, and no elaborate cover story. The three lines that work are worth reading before you need them.

And if the next tooth is looming, let them wiggle it themselves rather than staging an extraction. Loose teeth come out when they are ready, and a child who works one free with their own tongue over a week has done the whole thing properly, swallowed or not.
