Jeweled Teeth

A new study has shown how Native Americans had sophisticated knowledge of tooth anatomy, which allowed them to perform some remarkable dentistry, adding semiprecious gems to their teeth.

The study show how they were adding “bling” to their teeth as far back as 2,500 years ago, probably using a drill-like device with a hard stone such as obsidian, which is capable of puncturing bone and herb based anaesthetic to numb the pain.
