The short answer: if your child swallows a baby tooth, one pediatric dental source says it is usually harmless and the tooth passes on its own within days. Stay calm, and get medical help if there is choking, trouble breathing, pain, or vomiting. If the tooth is lost, write the tooth fairy a note and she can still come.

What happens if a child swallows a baby tooth?
According to Desert Kids Dental, the first step is to stay calm and reassure the child that swallowing a baby tooth is usually harmless. They advise watching for coughing, difficulty breathing or wheezing, and call 911 if there is choking. Otherwise they suggest water and soft foods, and say most swallowed baby teeth pass naturally within about 3 to 7 days without trouble, and that an X-ray is rarely necessary unless complications appear (Desert Kids Dental: https://www.desertkidsdental.com/post/child-swallows-baby-tooth-what-to-do).
They say to seek dental or medical evaluation if the child has persistent coughing, pain, or difficulty swallowing, a feeling that something is stuck in the throat with drooling or hoarseness, or abdominal pain or vomiting. A pediatric dentist can check that no tooth fragment remains and decide whether imaging is needed.
Timeframes vary, so treat any number as approximate and ask your own dentist or pediatrician.
What should I check first?
- Is the child breathing normally and comfortable? If not, call 911 or go to the emergency room.
- Was it a loose baby tooth that came out on its own? Or did the tooth come out after a fall or a hit? An injury is a different situation, and a dentist should see the child.
- Is it possible that a piece of the tooth was left behind or broke apart? Call the dentist.
- Is the child very young, or is there a dental appliance in the mouth? Call the dentist.
If the answer to each is no, and the child feels fine, most sources suggest watching and waiting.
Do I need to check for the tooth?
Many parents do, and it is fine if you do not. Some families like to look, and some prefer not to. If you decide to look, wear gloves, and do not feel bad if you cannot find it. The tooth fairy does not need the tooth to prove the gap.
What do I tell the child?
Tell the truth in a way that is calm and short: "The tooth went down with your drink. It is okay. Bodies know what to do with it." Children copy your reaction. If you are calm, they usually are too.
If your child is upset that the tooth is gone, offer the idea that the fairy knows which teeth come out. A note from the fairy is the easiest fix.
What if the tooth is lost instead of swallowed?
It happens constantly. The tooth falls out at school, in the car, at a restaurant, or in the sand. A few approaches:
- The child writes the fairy a letter. "Dear Tooth Fairy, my tooth fell out at the park and I could not find it. Here is a drawing." Children enjoy this. It gives them a role in the story.
- A reply from the fairy. A short note: "I know about the tooth. I was there. I have made an exception." Write it in tidy handwriting.
- A photo of the gap. A photo can stand in for the tooth.
- The drawing goes in the vial. If you have a vial, a small drawing of the tooth can go in it along with the note. We would not suggest it replaces a real tooth, but it keeps the story together.
What should the tooth fairy leave?
The same as always, or a little less. Some parents leave the same amount because the child did nothing wrong. Others leave a smaller gift and a note. Either is fine if you are consistent with later teeth. See our piece on how much the tooth fairy pays for ways to decide.
Can I prevent this?
A little. If a tooth is very loose, you can ask the child to tell you when it feels ready, and to tell you before it comes out. Do not pull a tooth that is not loose. A dentist can help with a tooth that seems stuck.
Some families do the following to protect the evening:
- Keep a small container in the car and in the child's bag, in case a tooth comes out away from home.
- Put a note in the tooth drawer with the plan.
- Keep a spare note from the fairy in the drawer for "lost tooth" emergencies.
When should I call a dentist?
Call if:
- The tooth came out after an injury.
- The tooth was not loose.
- A piece of tooth may be missing.
- There is heavy bleeding or bleeding that does not stop.
- The child has pain, trouble swallowing, cough, drooling, hoarseness, or vomiting.
- You do not know whether it was a baby tooth or a permanent tooth.
If a child is choking or having trouble breathing, call 911.
What if we have a keepsake kit?
If your child swallows the tooth, there is no tooth to gild, and the kit will wait. The vial stays empty until the next one. Our booklet's story works either way, because the Gold Tooth Fairy does not need the tooth in order to leave her gold dust. Sprinkle a small amount on the windowsill, away from the bed, and let her reply with a note.
