Most of us were raised on the golden rule of oral hygiene. Eat too many sweets, and you’ll end up paying for it in the dentist’s chair.
You enjoy the candy, scrub the evidence away with the sharp, intense, clinical sting of peppermint, and you’re as good as new.
But now it looks like the line between the snack aisle and the bathroom sink is somewhat blurring, and it’s doing so with a very familiar orange-and-yellow wrapper.
Reese’s has a new product with its name on it, and no, it’s not a candy bar.
The brand has teamed up with oral care company Hismile on a limited-edition toothpaste that’s meant to taste like a Reese’s Peanut Butter Cup—chocolate, peanut butter, and all—but in “brushing your teeth” form.
The catch is availability. The toothpaste is being sold only in Australia and New Zealand, as confirmed by company announcements. Hismile is offering it in bundles: either three or five tubes, each 3.5 oz, priced at $18.40 and $27.59.
A habit of peculiar pairings
Hismile says the flavor is meant to mimic the candy while still being sugar-free. The product listing leans hard into the dessert angle, describing it as a “dessert-like twist” on brushing.
This isn’t Hismile’s first “you’re joking” flavor. In 2025, the company collaborated with KFC on a fried chicken-flavored toothpaste, and it sold out in 48 hours.
And in the “real science, not brand stunts” corner, researchers at King’s College London announced last year that a toothpaste made from hair could help repair enamel and reduce tooth decay. The team envisions it being added to everyday toothpaste or used as a dentist-applied gel, with products potentially hitting shelves in the next two to three years, pending further testing and development.
So yes, Reese’s toothpaste exists. Just don’t expect to find it at your local shop unless you’re in Australia or New Zealand.
