7000 BC – The Bow Drill EraDentistry got its start in the Indus Valley of India and Pakistan. These industrious would-be dentists were master beadmakers who used bow drills to cure tooth problems. This is also the first appearance of dental assistants, whose duties consisted of restraining the flailing arms and legs of patients during the undoubtedly excruciating procedures. Still, this obviously beat a life without teeth  5000 BC – The Myth of the Tooth WormThe first and most enduring explanation for what causes tooth decay was the tooth worm, first noted by the Sumerians around 5000 BC. The hypothesis was that tooth decay was the result of a tooth worm boring into and decimating the teeth. This is logical, as the holes created by cavities are somewhat similar to those bored by worms into wood.The ivory sculptures below depict the havoc wrought by these wicked worms. The idea of the tooth worm has been found in the writings of the ancient Greek philosophers and poets, as well as those of the ancient Indian, Japanense, Egyptian, and Chinese cultures. It endured as late as the 1300s, when French surgeon Guy de Chauliac promoted it as the cause of tooth decay 700 BC – The First BridgesThe first society to use dental bridges and appliances were the Etruscans, starting around 700 BC. The image below shows a similar dental bridge created by the Egyptians that uses gold wires to hold the teeth together. This is also the first incarnation of a cosmetic dental practice that would come to be know as “bling”. The Art of ExtractionUp until the 16th century, dedicated dentists did not exist and dentistry was practiced by general physicians and barbers. The staple procedure of these early dentists was the extraction, which was used to alleviate pain and halt tooth decay. Over the years, a number of tools were invented for performing this procedure.The images below display several variations of the Dental Pelican, which was invented in the 14th century by Guy de Chauliac and used until the late 18th century.    The pelican later gave way to the Dental Key.     In the 20th century, the key was replaced by the forceps, which are still in use today.   | |
