But it's clear that people—mostly men—from nearly all walks of life opted for the look, noted José Concepción Jiménez, an anthropologist at the institute, which recently announced the findings.
"They were not marks of social class" but instead meant for pure decoration, he commented in an e-mail interview conducted in Spanish.
In fact, the royals of the day—such as the Red Queen, a Maya mummy found in a temple at Palenque in what is now Mexico—don't have teeth decorations, Jiménez said.
Other evidence of early Mesoamerican dentistry—including a person who had received a ceremonial denture—has also been found.
The early dentists used a drill-like device with a hard stone such as obsidian, which is capable of puncturing bone.
"It's possible some type of [herb based] anesthetic was applied prior to drilling to blunt any pain," Jiménez said.
The ornamental stones—including jade—were attached with an adhesive made out of natural resins, such as plant sap, which was mixed with other chemicals and crushed bones, Jiménez said. The dentists likely had a sophisticated knowledge of tooth anatomy, Jiménez added. For example, they knew how to drill into teeth without hitting the pulp inside, he said.
"They didn't want to generate an infection or provoke the loss of a tooth or break a tooth."
