A tooth that no one could see hid the proof.

Scientists analyzed a back molar with a jade inlay and discovered something that changes the history of Maya dentistry: it was not just a symbol of status. 3D images showed calcification in the dental pulp, a sign that the procedure was performed on a living person and with a clear purpose: to relieve pain and treat real cavities.

The most surprising thing is in the cement that held that stone in place for more than a thousand years: a mixture of calcium, phosphates, bitumen, and essential oils, designed with a precision that still amazes specialists today. If you think modern dentistry invented everything, this stone in a hidden tooth says otherwise.
