Across the world, losing a baby tooth is a milestone that cultures have marked with ceremony and tradition for centuries. From fairies to mice, from burying teeth to tossing them toward the sky, the rituals vary widely — but the underlying message is often the same: this is a moment worth celebrating, and strong new teeth are worth hoping for. At Newton Smile Centre, we love how these traditions reflect the universal human understanding that teeth matter.
The Tooth Fairy: An American Classic
Most children in the United States grow up expecting a visit from the Tooth Fairy after placing a lost tooth under their pillow. In exchange, they find a small gift or coins left behind overnight. The modern Tooth Fairy emerged from a blend of European folklore and became widely popular through 20th-century American culture.
The Tooth Fairy’s genius — from a parenting perspective — is that it transforms an anxious or uncomfortable experience into an exciting one. Children who dread wiggly teeth suddenly have a reason to look forward to losing them, which sets a positive tone for dental milestones throughout childhood.
The Tooth Mouse: Europe and Latin America
In many European and Spanish-speaking countries, a small mouse takes the place of the fairy. In France, the character is La Petite Souris — “the little mouse.” In Spain and Latin America, the beloved figure is Ratón Pérez, who collects baby teeth from under pillows and leaves coins or small presents in their place.
The tradition of a tooth-collecting mouse dates to at least the 17th century in some parts of Europe, predating the modern Tooth Fairy by hundreds of years. Whatever the cultural variation, the exchange of a tooth for a small reward is a strikingly universal concept.
Throwing Teeth for Good Luck: East Asian Traditions
In China and Japan, the direction a tooth is thrown depends on which jaw it came from. Lower baby teeth are thrown upward — toward the sky — with the wish that the adult tooth growing to replace it will grow strong and straight. Upper baby teeth are thrown downward — toward the earth or under the floorboards — for the same reason.
The physical act of throwing carries symbolic meaning: the hope that the new tooth will follow the trajectory of the one thrown before it. It is a simple, intuitive gesture that connects dental health with optimism.
Burial Traditions and Medieval Superstitions
In medieval Europe, the handling of lost teeth was a matter of serious concern. Superstition held that witches could use a person’s baby teeth to gain power over them, or that an improperly disposed-of tooth could cause problems in the afterlife. The safest solution was to bury the tooth or burn it entirely — removing it from the world and preventing any supernatural misuse.
Some cultures buried baby teeth near trees or in the ground with the belief that doing so would encourage strong adult teeth to grow in their place, connecting the loss of the old tooth to the health of the new one.
Why These Traditions Matter for Dental Health
Beyond their charm, tooth loss traditions serve a real purpose: they make the experience feel meaningful rather than frightening. Children who are anxious about losing teeth — or about going to the dentist — often carry that anxiety into adulthood. Framing tooth loss as a rite of passage, one that is celebrated and rewarded, builds a healthier relationship with dental care from the very beginning.
At Newton Smile Centre, we work with patients of all ages from Newton, Brookline, Cambridge, Watertown, and throughout the greater Boston area. Part of our philosophy is helping patients feel comfortable and confident about their dental health at every stage of life — and it often starts in childhood.
Frequently Asked Questions About Baby Teeth and Dental Development
When do children typically start losing baby teeth?
Most children begin losing their primary (baby) teeth around age six, starting with the lower front teeth. The process continues gradually through the early teenage years, with the last baby teeth typically lost around age twelve or thirteen. The timing varies significantly from child to child, and there is a wide range of what is considered normal. If you have concerns about a child’s tooth development, a dental exam is the best way to get a clear picture.
Do baby teeth really matter if they fall out anyway?
Absolutely. Baby teeth serve as placeholders that guide the adult teeth into the correct position. They also allow children to chew and speak properly during the years when speech patterns are developing. If baby teeth are lost prematurely due to decay or injury, the surrounding teeth can shift and block the space the adult tooth needs to erupt correctly. Keeping baby teeth healthy until they are ready to fall out on their own is an important part of your child’s long-term dental development.
How should I care for my child’s baby teeth?
Begin cleaning your child’s mouth even before the first tooth appears by wiping the gums with a soft, damp cloth. Once teeth erupt, brush twice daily with a soft-bristled brush and a rice-grain-sized smear of fluoride toothpaste for children under three, increasing to a pea-sized amount for children three and older. Begin flossing when two teeth touch each other. Schedule the first dental visit by the child’s first birthday or when the first tooth appears, whichever comes first.
When should my child first see a dentist?
The American Academy of Pediatric Dentistry recommends that a child’s first dental visit occur by their first birthday or within six months after the first tooth appears, whichever comes first. Early visits help establish a dental home, allow providers to check for early signs of decay, and begin building a positive association with dental care. Newton Smile Centre welcomes young patients and their families for consultations to get their dental health journey started on the right foot.
