The tooth fairy is one of the strangest economic actors in your child's life. She — or he, or they, your tooth fairy can be whatever you want — turns up every few months with no apparent income source, and leaves a small amount of money in exchange for a calcified piece of your child that you, the parent, were going to throw away anyway. Honestly, the racket is impressive.
She also creates one of the easiest, most recurring money conversations you'll have, for about five years straight.
But she causes parents a surprising amount of anxiety, mostly around two questions. How much should the tooth fairy leave? And what do I say when my kid finds out their friend got more? Here's how I'd handle both.
The amount question
There is no correct amount. There is no chart. (Well, there is, on Pinterest, but the Pinterest chart says $20 per tooth, which is — and I say this as someone who likes a fun tradition — completely unhinged.)
The actual range, across real families I know, is $1 to $5. Most families settle around $2-3. Some go fancier for the first tooth ($5-10) and back to normal for the rest. Some never go above $1, ever. All of these are fine. The amount matters less than the consistency.
A few things to keep in mind:
Whatever you start with, you're stuck with. If you put $10 under the pillow for tooth #1, you're going to feel pressure to do $10 for tooth #2, and tooth #3, and so on for twenty teeth. Multiply $10 × 20 and decide if that's a tooth-fairy budget you want to commit to. (It's $200. Per child.) Many families bump up for the first tooth not realizing this baseline-setting effect.
Lower is, honestly, fine. Some of the most magical tooth-fairy memories kids have are about getting a single shiny gold dollar. The presentation can matter more than the amount.
Inflation isn't real to children. A $2 tooth fairy in 2027 is not "stingy" because $2 buys less than it did in 2002. Your kid has no historical frame. They will be delighted by whatever the tooth fairy decides to leave, especially if she also leaves a small note.
The amount that works for your family is the amount you can sustain for every tooth, for every kid, without resenting it.
The "friend got more" conversation
Sooner or later — usually around the second or third tooth, or after a sleepover — your kid will report back.
"Mom. Liam got TEN DOLLARS for one tooth. The tooth fairy gave him ten dollars."
The temptation here is to either dismiss it ("Well, the tooth fairy is different in every house") or feel guilty and quietly raise your own amount. Don't do either right away. Try this instead:
"Yeah, the tooth fairy is different for every family. She brings different amounts to different houses, kind of like how different families have different rules about bedtime or how often they eat ice cream. The amount isn't really the point."
Then, optionally: "What did you do with what the tooth fairy left you last time?"
Watch your kid pivot. They were grumpy for about thirty seconds. Now they're remembering their own tooth-fairy experience and what they did with the money. The comparison fades. The personal memory replaces it.
This is one of the rare cases where the conversation can stay this short. You don't need a long discussion about other families' choices. Just: the amount varies, and that's normal, and we don't worry about it.
What to do with the money when it arrives
The tooth-fairy money is, for many kids, the most cash they ever hold at once. It's also money that didn't come from chores or allowance, so it has a slightly magical quality that allowance money lacks.
A few options for what to do with it, depending on age:
Ages 4-6. Right into the spend jar (if you're running the three-jar system) or sorted across the jars. Resist the urge to direct it all into save — at this age, having some immediate spending power makes the tooth-fairy moment feel real and rewarding.
Ages 6-8. A small conversation about what to do with it. "You have $3 from the tooth fairy. What do you want to do with it? Spend, save, or split?" They will sometimes choose to save all of it for a bigger goal they're working toward. That's their choice, not your pressure.
Ages 8+ (when tooth-fairy belief is fading or has faded). This becomes a slightly more grown-up conversation. The "tooth fairy" might be openly Mom-and-Dad at this point, and the cash exchange can be more direct — a small reward for being a kid losing teeth like all the kids do.
In any case, the money should land somewhere they can see, not vanish into a piggy bank or "Mom's savings for you." Cash that disappears immediately doesn't feel real. The point of the tooth-fairy ritual is the tangible nature of the exchange.
The recurring nature is the gift
Most lessons about money are one-shot. The tooth fairy is unique in that she visits ten, twelve, sometimes twenty times across your kid's childhood. That's twelve to twenty mini money conversations spread over years — each one a chance to talk about what to do with a small unexpected windfall.
By the time the molars start falling out (around age 9-11), your kid has had years of low-stakes practice making small money choices: spend now, save toward something, split it. The skill they develop through these tooth-fairy moments is deciding what to do with unexpected money, which is exactly the skill that fails most adults later in life with tax refunds, bonuses, and small inheritances.
Plant the habit now. Twelve teeth's worth of practice is more than most kids ever get. Hang on to that.
The amount can be $2. The conversation is what costs nothing and matters most.
