Trepanation — drilling a hole in a living person's skull — is the oldest known surgical procedure.
Evidence found in skulls from 7,000 BC.
What's stranger: many patients survived.
The bone shows regrowth around the holes, meaning the person lived for years afterward.
We still don't know why they did it. Pain relief? Spirits? Epilepsy?
It's still performed in modern medicine for brain bleeds.
The oldest surgery is still in use.

Vikings didn't just pull teeth — they filed them.
Archaeologists have found Viking skulls with deep horizontal grooves filed into the front teeth.
It was deliberate, symmetrical, and done on adult men.
No one knows exactly why. The leading theory: intimidation.
Imagine rowing toward an enemy ship and the men on the other side are grinning at you with filed fangs.

Edgar "Painless" Parker became the most famous dentist in America by being completely unhinged.
He pulled teeth in the street from a carnival stage. He had a band, a clown, and a live orchestra to drown out the screaming.
By 1915, his chain had 28 dental offices across California.
The state dental board tried to shut him down. Their argument: "Painless" was false advertising.
His response: he legally changed his first name to Painless.
Edgar Painless Parker. Licensed dentist.

James Barry performed one of the first successful caesarean sections in history in 1826.
Barry was also a military surgeon, rose to Inspector General of British army hospitals, and improved conditions in military prisons and leper colonies.
When Barry died in 1865, the person preparing the body made a discovery.
James Barry had been born a woman.
Barry had lived as a man for over 40 years. The military covered it up.
The medical establishment refused to believe it for decades.

Lucy Hobbs applied to dental school in 1859.
They rejected her. Women couldn't be dentists.
She apprenticed under a dentist instead, built a thriving practice, and applied again.
This time the Ohio College of Dental Surgery admitted her as a student — then gave her full credit for her years of practice.
She graduated in 1866. First woman in history to earn a dental degree.
She immediately started training other women.

The Waterloo Teeth were dentures made from the teeth of dead soldiers.
After the Battle of Waterloo in 1815, scavengers pulled teeth from 50,000 corpses on the battlefield.
These were exported to England and used by dentists for the next decade.
They were considered premium quality.
Demand for battlefield teeth was so high that soldiers started pulling teeth from the living.

Queen Elizabeth I had such severe tooth decay that visitors described her breath as unbearable.
By her 60s, she had lost so many teeth her cheeks had sunken in. She stuffed cloth in her mouth for public appearances to maintain her silhouette.
Sugar had just arrived in Europe from the New World.
The wealthy consumed it obsessively.
Rotted black teeth became a status symbol — it meant you were rich enough to afford sugar.
English

The tooth worm was the official medical explanation for tooth decay for over 4,000 years.
Ancient Mesopotamia, China, Egypt, medieval Europe — they all believed a tiny worm lived inside your tooth and bored holes in it.
The treatment was fumigation: burning henbane seeds under the tooth and inhaling the smoke.
Henbane is toxic and mildly hallucinogenic.
The worm theory wasn't officially disproven until 1728.

In ancient Rome, having white teeth was a sign of wealth.
The whitening method: human urine.
Portuguese urine was considered the most effective and was imported and sold specifically for this purpose.
The ammonia in urine actually works as a bleaching agent.
Dentists used versions of this until the 1800s.
