Tooth Fairy Letter Generator

First tooth, lost tooth, or the night the fairy forgot.

Published Oct 29, 2026

A tooth fairy letter, printed small enough to fit under a pillow. Pick the situation: first tooth, a tooth that got lost before the fairy could collect it, or the night the fairy forgot and owes an apology. That last one is on here because it happens to everybody, and it'll happen to me. Fill in the name, print, fold.

Nothing you type here is saved.

How to use it

  1. Type your kid's first name and pick the situation: a normal visit, the fairy forgot, the tooth got lost, a wiggly tooth, or one of the last baby teeth.
  2. Pick which tooth, what the fairy left (or leave money out of it), and sweet or funny.
  3. Hit "Write the letter" and read it over. Generate again if it's not quite right.
  4. Print. You get four pillow-size copies on one sheet with cut lines. Cut one out, fold it twice, tuck it under the pillow with whatever she left.

The Night the Tooth Fairy Forgets

It happens to everybody. The tooth goes under the pillow, everyone goes to bed, and in the morning it's still there. You are not the first parent to stand in a hallway at 6:40 a.m. doing very fast math about where the cash is.

The fix is a tooth fairy apology letter. Pick "The fairy forgot" above and the letter says sorry, gives a reason a kid will buy (the busiest night of the year, a storm, a wrong turn at the clouds), and leaves a little extra to make up for it. It never blames the kid, and it never blames you. This is the sample:

✦ A note from ✦

The Tooth Fairy

Dear Ava,

I'm so sorry. Last night was the busiest night of the whole year. Eleven teeth on your street alone, a very windy sky, and somewhere between the clouds and your window I got completely turned around.

Your tooth was waiting right where you left it, and I didn't come. That's my mistake, not yours. So tonight I flew here first, and I left double, because a tooth that patient deserves it.

Keep brushing that gap. Something new is growing in there, and I'll be checking on it.

Love (and sorry again), the Tooth Fairy

P.S. My wings are still a bit windblown. Please don't tell the other fairies.

When the Tooth Gets Lost

Swallowed at dinner, dropped down the sink, gone somewhere between the playground and the car. A lost tooth is a real worry for a six-year-old, because no tooth means no fairy. Pick "Tooth got lost" and the letter says the fairy knows it came out, it's safe in Fairyland's lost-and-found, and she left the gift anyway.

Something like: "Dear Leo, I heard your tooth fell out at lunch and went on an adventure of its own. Don't worry. Lost teeth always find their way to me eventually. I knew it was yours, so I left your coin anyway. Love, the Tooth Fairy." Have them write a note to leave under the pillow too, explaining what happened. They'll take it very seriously.

Tooth Fairy Letter Ideas by Situation

Eight ideas, one line each. The first five are built into the generator above. The last three are easy to write by hand from the same shape.

  • •First tooth ever: a welcome-to-the-club letter, and usually a little more cash than usual.
  • •The fairy forgot: an apology, a believable excuse, and double.
  • •Lost tooth: the tooth is safe in Fairyland's lost-and-found, gift left anyway.
  • •Wiggly tooth: no money yet, just "I've heard it's loose, no rush, I'll be ready."
  • •Last baby tooth: a more grown-up letter about all the years of visits.
  • •Pulled at the dentist: the fairy heard they were brave in the big chair.
  • •Two teeth at once: the fairy needed a second bag.
  • •A sibling's first tooth: the older kid gets a note asking them to show the little one how it works.

What to Write in a Letter from the Tooth Fairy

A letter from the tooth fairy to a child only needs four things: the kid's name, the tooth ("your first tooth" or "that wiggly front one"), what she left, and one small magic detail (where the teeth go, how tiny her handwriting is, the dog who almost woke up). Keep it under about a hundred words. It has to fit under a pillow, and it's usually read at 6 a.m. by someone who is very excited.

Skip the brushing lecture, or keep it to one line. The letter's job is to make the morning, not to sell floss.

How Much Does the Tooth Fairy Leave?

There's no official rate. A lot of families land somewhere between a dollar and five dollars a tooth, often with a bit more for the first one. The number matters less than keeping it steady: kids have 20 baby teeth, and they will compare notes at school.

The generator only mentions the amount you pick, or none at all if you choose "Don't mention it," so the letter never promises more than what's actually under the pillow.

Handwritten vs. Printed Tooth Fairy Letters

Printed is fine. The letters print small on purpose, four to a page, in a tiny fairy-sized layout, so there's no handwriting for a sharp-eyed kid to compare with yours.

If you want a handwritten tooth fairy letter, generate one here and copy it out by hand in five minutes. Write small, in a pen color you never use for anything else. Glitter pen if you're brave. Fold it twice so it actually fits under a pillow.

Tips

Pillow-size or it doesn't count

Fold it in quarters. A full sheet of paper under a pillow crinkles, wakes them up, and blows the whole operation.

Know where the cash is before bedtime

Find the dollar while they're still awake. Digging through the car cup holder at 11 p.m. is how the fairy ends up writing an apology.

Write the date on the back

Which tooth, how old they were. Ten seconds now, and it's a page for the baby book later.

Glitter is a trap

A little fairy dust on the windowsill is magic. You will also be finding it in the carpet until they lose their next tooth.

Frequently Asked Questions

What do you write in a tooth fairy letter?

The kid's name, which tooth, what the fairy left, and one small magic detail, in under a hundred words. The generator above writes it from the name, the tooth and the situation you pick, and prints it pillow-size.

What if the tooth fairy forgot?

Leave an apology letter the next night with a little extra. Pick "The fairy forgot" above: she says sorry, blames a busy night or a windy sky, and leaves double. It happens to everyone, and kids love the apology letter more than the regular one.

What if we lost the tooth?

Pick "Tooth got lost." The letter tells your kid the fairy knows the tooth came out, it's safe in her lost-and-found, and she left the gift anyway. A note from your kid explaining what happened is a nice touch.

How much money does the tooth fairy leave?

There's no set rate. Plenty of families land between a dollar and five dollars a tooth, with a little more for the first. Pick an amount you can keep up for all 20 baby teeth.

How do I print a tooth fairy letter small?

Hit "Print pillow-size letters" and it prints four quarter-page copies on one sheet, with cut lines. Choose Save as PDF in the print window if you want a file. Your kid's name isn't saved anywhere.
