Dental Prosthetics Through the Ages
Every workday, dental laboratory technicians get to create the bridges, crowns, and other dental prosthetics that serve millions of Americans every year. According to the American Academy of Implant Dentistry, over 35 million Americans are missing teeth in one or both jaws. Filling those gaps is no small task, and DLTs use cutting-edge technology and a steady hand every day to create personalized prosthetics and complete smiles.
However, fixing teeth is nothing new. Humans have been replacing old teeth for millennia; it’s been a long road to the modern dental lab. Future dental lab technicians, discover the treatments dreamed up by generations past that led to where you are today.

Stone Age dentistry
Human beings have had cavities for as long as they’ve had teeth, and that means dentistry has been around since we made the connection between oral pain and tooth decay. Even in ancient times, people were trying to treat cavities, though full dental prosthetics were still a long way off.
A find in northern Italy revealed that humans were treating cavities around 13,000 years ago. Instead of a prosthetic, though, the ancient dentist scraped out the holes and filled them with bitumen, a tarry substance used for making tools. Other ancient evidence suggests cavities were scraped with stone tools, a far cry from today’s dental technology.

Several centuries passed between the dawn of dentistry and early prosthetics, but gold made it’s debut around 2,500 years ago. And dentistry made extensive use of gold for a long time after. Historians disagree on the particulars of diagnosis and treatment, but one find from Egypt in the third millennium B.C. suggests one of the earliest uses of gold wire to hold teeth in place.
Gold may have had certain aesthetic benefits for ancient patients, but its real utility in dentistry is that it’s non-reactive. Gold can interact with water, air, food, and the environment of a person’s mouth without rusting or wearing. Early unambiguous (and rare) examples of prosthetics were fashioned entirely from gold, predating the Roman empire.
The Etruscans were a people who lived on the Italian Peninsula prior to the emergence of the Romans. Etruscans crafted some of the oldest known dental prosthetics and appear to have made one of the earliest attempts at dental bridges. Gold and silver bands held together rows of teeth that could be inserted into someone’s mouth, filling a gap.
Some Etruscan archaeological evidence suggests that these bridges replaced teeth that had been removed deliberately. That means ancient healthcare providers were diagnosing bad teeth, removing them, and replacing them with crafted prosthetics centuries before the height of the Roman empire. It’s a basic dentistry model that’s not too far off from what happens today.
Millennia later on a different continent, a famous American would craft bridges in a way that would have been familiar to the Etruscans.

Paul Revere, tooth maker
Paul Revere is best known for his midnight ride, telling his fellow American colonists of an impending invasion by the British military. But, Paul Revere’s other talents included dentistry. Revere was a silversmith by trade, and he occasionally crossed over into making dental prosthetics, usually from ivory.
In 1775, Revere was able to identify the body of a friend who’d perished at the Battle of Bunker Hill, Major General Joseph Warren, thanks to a bridge Revere had crafted himself. It’s one of the first examples of the use of dental records and prosthetics to posthumously identify a body.

Into the modern era with ceramics
Modern dental prosthetics perform the same functions as the teeth made by ancient artisans or Paul Revere, but they differ in an important way. Modern prosthetics are often made of ceramic, as opposed to real teeth and metal. The development of dental ceramic stretches back to 1889 when Charles H. Land introduced a crown covered in porcelain, referred to as a “jacket.”
These early ceramic crowns were prone to cracking, but by the 1950s, methods of fusing ceramic to metal had been developed. In the 1980s and 1990s, we see the development of modern crowns and bridges. Today, modern dental prosthetics are held firmly to a patient’s jaw and are often indistinguishable from natural teeth. There’s no glint of gold or the discomfort of a poor fit; prosthetics are simply brand new teeth.
Modern DLTs are still solving a human problem that’s been with us through the ages. Do you want to continue the tradition of crafting prosthetics as a dental lab technician?
