Centuries earlier, Maya kids as young as 7 had “tooth gems” — jade inlays in their teeth that most likely represented social maturity or an initiation rite, a brand-new research study discovers.
Archaeologists currently understood that pre-Hispanic Maya grownups frequently sported tooth inlays. “what is tantalizing is the young age of the individuals” examined in the brand-new research study, the authors composed
in the research study.
A brand-new research study in the November 2025 concern of the Journal of Archaeological Science: Reports taken a look at 3 separated teeth with jade inlays housed at the Popol Vuh Museum in Guatemala. Based upon the degree of each tooth’s root development, the scientists figured out that each tooth had actually originated from a kid in between 7 and 10 years old.Tooth styleAmong the embellished teeth was an upper main left incisor– among the upper front teeth– and another was a best upper dog. The 3rd tooth was a lower incisor. It’s unidentified if they all originated from a single kid.
“Unfortunately, these teeth are not associated with bony skeletal remains,” the authors composed in the research study, “so we cannot state for certain their origin and whether or not they belong to a single individual or to up to three different ones.”
According to the research study, the Maya typically intentionally formed their teeth by filing or inscribing them. It was likewise typical for craftsmens to utilize stone tools to sculpt synthetic holes in the surface areas of popular teeth and to put gems there– generally jade, however likewise obsidian or pyrite– that were repaired in location with natural glue.

There is some proof that teenagers in between 10 and 15 years of ages had teeth that were submitted or inscribed, however these people didn’t have oral inlays, the research study kept in mind. There is likewise “a very limited number” of Maya in between the ages of 15 and 20 who had oral inlays in the historical record, they composed.
It’s possible that the Maya didn’t put oral inlays on more youthful people due to the fact that it might have harmed growing teeth. One concept is that “inlays might have been too invasive a procedure to be performed on such young individuals,” the group composed in the research study. X-rays of the 3 teeth in the brand-new research study showed that the innermost layer, understood as the oral pulp, wasn’t harmed and that the teeth did not have natural caries, or cavities.
Mysteries stayAn analysis of the 3 teeth recommends that the inlays were put in while the kids lived, the authors composed.
This is a crucial discovery due to the fact that 2 teeth with jade inlays discovered in Belize might have been from a kid as young as 3. That discover is “controversial,” in part since the inlays might have been developed after death as part of a burial routine, the authors of the brand-new research study composed.
They likewise warned that the brand-new discovery may show a local or regional custom that was not prevalent throughout the Maya world or that the oral inlays were an indication that a kid had actually started handling adult duties, such as household chores or laboring.
Up until more oral inlays are discovered in the teeth of Maya kids, it will be challenging to identify why these children had them.
“Unless more cases are documented, any possible interpretation of the reasons behind performing these permanent modifications in such young individuals remains at the level of assumptions and cannot be generalized to the whole Maya realm,” the authors composed in the research study.
