Paul Revere did more than make his famous midnight ride. He was skilled in the art of dentistry. From 1760-1770, he placed advertisements in a Boston newspaper offering his services as a dentist.

He was trained by the same dentist who made George Washington’s dentures and is one of dentistry’s forefathers.

Images of Saint Appolonia can be seen in dental college and European churches. She is portrayed holding forceps and extracted teeth.

Hippocrates and Aristotle both wrote about out dentistry. This was from 500-300 BC. They described the pattern of tooth eruption, treatments for decayed teeth and gum disease, tooth extraction with forceps and the use of wires to hold together loose teeth and fractured jaws. But wait, in 5000 BC, a Sumerian text describes dental decay as “tooth worms” and about 260BC, an inscription on the tomb of Hesy-Rey an Egyptian scribe, includes the title “the greatest of those who deal with teeth, and of physicians.” This inscription reference identifies the earliest dental practitioner.
