Every kid loses their teeth. It’s messy, it’s memorable, and it’s one of the most universal childhood milestones. But until now, the Tooth Fairy never had a toy to call her own.

Enter The Tooth Sleuth, a cuddly detective mouse who’s already blowing up on TikTok, Instagram, and in family group chats everywhere. Parents are calling it “Elf on the Shelf for teeth,” and kids are waking up every morning eager to find where their Sleuth is hiding.

The buzz is real. The Sleuth isn’t just a toy. It’s a story, a ritual, and maybe even the next global tradition.

A Fresh Take on the Tooth Fairy

The set comes with everything parents need to turn a wiggly tooth into a magical event:

  • The Sleuth plush, a peppermint-striped tie, glasses, and soft fur.
  • A hardcover storybook explaining the lore of the Tooth Sleuths.
  • A tooth pouch to keep lost teeth safe under the pillow.
  • A milestone tracker to mark every lost tooth.
  • A letter from the Tooth Fairy herself.

The lore? Each Sleuth is trained in the Fairy Realm to monitor brushing, kindness, and bedtime routines. Every night, they “report back” to the Tooth Fairy, and every morning, kids discover their Sleuth in a new hiding spot.

It’s a simple system with a big payoff: magic for kids, structure for parents.

Why It’s Going Viral

The Tooth Sleuth is designed for shareability. Parents film the morning search. Kids squeal when they find the plush in a bookshelf or a cereal box. The videos are short, sweet, and TikTok-perfect.

One clip of a child shouting “He’s in the fridge!” has already racked up thousands of views. Parenting influencers call it “the hack we didn’t know we needed.”

And unlike holiday-only toys, The Tooth Sleuth is evergreen. Kids lose teeth year-round, which means content opportunities never stop.

The Inventor Behind the Hype

If this all sounds like the formula for a hit, it is. Natalie Rebot, the Canadian inventor behind The Tooth Sleuth, has done this before.

Her first invention, Moonlite, turned smartphones into storybook projectors. It became one of Kickstarter’s most-funded toys ever, went viral worldwide, and sold millions of units in over 100 countries.

Now, with The Tooth Sleuth, she’s bringing that same magic to the Tooth Fairy — one plush, one story, one lost tooth at a time.

Why Parents Love It

Parents aren’t just buying into the magic. They’re buying into the purpose.

  • The Sleuth encourages daily brushing without nagging.
  • The “no-touch” rule (if kids touch it, it “loses its magic”) keeps the ritual consistent.
  • The analog design means no screens, no apps, no logins.

“I was tired of bribing my son to brush,” says one LA mom. “Now, the Sleuth does it for me. He actually runs to the bathroom at bedtime.”

A Global Tradition in the Making

The Tooth Fairy exists everywhere, from Ratoncito Pérez in Spain to slippers in South Africa. But until now, there’s never been one shared product that unites all those traditions.

That global potential is why insiders call The Tooth Sleuth “Elf on the Shelf 2.0”. It’s not a fad, it’s a framework. If the early buzz is any indication, this tiny detective mouse might be the most talked-about toy of the year.

At $39.99 USD, The Tooth Sleuth is affordable, giftable, and viral by design. Families can buy it now, with retail launches coming soon.
