Garengeot Dental Key

Used from the 19th century through the 1930s...!

Chrome-plated dental key

The invention of this extractor is attributed to the French military surgeon René-Jacques Croissant de Garengeot in the early 18th century, who adapted the corkscrew mechanism for extracting molars, replacing the older “pelicans,” a type of dental instrument.

Date: Late 19th century – early 20th century (c. 1885–1905)

An instrument designed to extract molars through a twisting and pulling motion, often used by dentists for its ease of use but heavily criticized in the 19th century for the damage it could cause—such as tearing off pieces of gum or fracturing teeth—during extraction...

Developed in the late 19th century to meet hygiene and heat sterilization requirements (asepsis), this all-metal version eliminated putrescible organic materials such as wood or ivory.

The addition of a clamping screw made it possible to adjust the hook’s position to fit the shape of the tooth to be extracted or to change hooks, while maintaining the fundamental mechanical principle of extraction using a rotating lever.

The instrument operates on the principle of a lever: the fixed hook grips the neck of the tooth while the body rests against the gum, applying a sharp lateral twisting motion to dislodge the tooth from its socket. The tooth, wedged between a hook and a key-shaped blade, could not withstand the operator’s twisting motion—similar to that used to open a lock—hence the instrument’s name. Sometimes, along with the tooth, a piece of the jawbone was removed...

Trauma and damage: The force of this centrifugal rotation caused major trauma: frequent fractures of the alveolar bone and jaw, breakage of adjacent teeth caught in the pivot point, and severe lacerations of the oral soft tissues.

Despite its proven clinical danger, this instrument and its variants continued to be manufactured and marketed in surgical instrument catalogs continuously until the 1930s, before being definitively replaced by the dental forceps.

The dental forceps, thanks to axial gripping via anatomically shaped jaws and controlled rocking movements, finally put an end to the ravages caused by dental levers by preventing destructive pressure on adjacent teeth and preserving the patients’ bone integrity.

Length: 15cm
