Pierre Fauchard (1678-1761) was a largely self-taught French dental surgeon, trained as a navy surgeon before settling in Paris to practice dental care exclusively — an unusual path at a time when this was still commonly done by barbers or itinerant tooth-pullers.
His major work, Le Chirurgien Dentiste, ou Traité des Dents (1728), is the first systematic treatise entirely devoted to dentistry: two volumes, over 800 pages, describing more than 100 oral conditions — including periodontal disease ("pyorrhea") and its treatment. Before publishing, Fauchard submitted his text for review to 19 colleagues (royal physicians, surgeons) — a process not unlike modern peer review in spirit.
In the 18th century, dentistry was not recognized as a distinct medical discipline. It was practiced without standardized training, often by itinerant practitioners. By clinically documenting conditions and their treatments, Fauchard laid the groundwork for a reasoned, transmissible, verifiable practice — a clean break from the prevailing empiricism.
His explanations of the causes of periodontal disease are, unsurprisingly, those of his time — more than a century before germ theory and two centuries before Löe's work on dental plaque. What stands out in hindsight is less the medical content than the method: systematic clinical description, classification of conditions, peer validation before publication. It is this methodological rigor that allowed his work to remain a reference long after its pathophysiological explanations were superseded.
Fauchard is today considered the father of modern dentistry — to the point that an international learned society, the Pierre Fauchard Academy, still bears his name. His contribution to periodontology isn't a specific treatment that survived the centuries, but a method: documenting, classifying, and clinically validating, rather than passing down unverified oral knowledge.
