The History and Use of the Dental Key: A Grim Tool of Early Dentistry
Introduction
The object in the image you found under the floorboards is a fascinating and somewhat unsettling relic of medical history known as a dental key. Dating back to the 18th and 19th centuries, this tool was commonly used by early dentists and surgeons for tooth extractions. The design of the dental key evolved over time, but its basic function remained the same: to remove teeth in a manner that often caused extreme pain and sometimes significant injury to the patient. Understanding its history and how it was used offers a glimpse into the development of modern dentistry and how far we’ve come in terms of patient care and medical technology.
Origins of the Dental Key
The dental key, or tooth key, first appeared in the early 1700s as an answer to the growing problem of tooth decay and infection. Before modern anesthesia and painkillers, tooth pain was an agonizing experience for many people, and the only solution available was extraction. While modern dentistry employs anesthesia and precise instruments, tooth extractions in the 18th and 19th centuries were much more brutal.
The design of the dental key is reminiscent of a locksmith’s tool, hence the name. Its early versions featured a long metal handle, similar to that of a door key, with a claw at the end that would grip the tooth. The user would place the claw around the tooth to be extracted and twist the handle, often violently, to yank the tooth out of the patient’s mouth. Unfortunately, this method frequently caused damage to surrounding teeth and gums, and it was not uncommon for the tooth to break mid-extraction, leading to further complications.
The Design of the Dental Key
At first glance, the dental key might look more like an instrument of torture than a medical tool. Its metallic body featured a curved, serrated claw designed to hook around the tooth, with finger rings for the user to grip tightly as they applied force. The process was simple but crude:
Placement: The dentist or barber-surgeon would place the claw of the key around the targeted tooth, positioning it as close to the gumline as possible.
