Pierre Fauchard (January 2, 1679 – March 21, 1761) was a French physician, credited as being the "father of modern dentistry". He is widely known for writing the first complete scientific description of dentistry, Le Chirurgien Dentiste ("The Surgeon Dentist"), published in 1728. The book described basic oral anatomy and function, signs and symptoms of oral pathology, operative methods for removing decay and restoring teeth, periodontal disease (pyorrhea), orthodontics, replacement of missing teeth, and tooth transplantation. Biography Early years Fauchard was born in a very modest home in Saint-Denis-de-Gastines in 1679. In 1693 he joined the French Royal Navy at the age of 15, much to his family's distress, and came under the influence of Alexander Poteleret, a surgeon major, who had spent considerable time studying diseases of the teeth and mouth. During that time, Fauchard learned that sailors who were on long voyages suffered severely from dental ailments, scurvy in particular. Eventually Major Poteleret inspired and encouraged him to read and carefully investigate the findings of his predecessors in the healing arts. He said he wanted to disseminate the knowledge he learned at sea based on actual practice. This idea led Fauchard to become a combat medic as Poteleret's protégé. Life as young dentist Once Fauchard left the navy, he shortly settled down in Angers, where he practiced medicine at the University of Angers Hospital. In Angers, he started much of the revolutionary medical work we know today, and he was the pioneer of scientific oral and maxillofacial surgery. Fauchard often described himself as a "Chirurgien Dentiste" (surgical dentist), a term very rare at the time as dentists in the 17th century generally extracted decayed teeth rather than treating them. Despite the limitations of the primitive surgical instruments during the late 17th and early 18th century, Fauchard was considered a highly skilled surgeon by many of his colleagues at Angers University Hospital. Fauchard made remarkable improvisations of dental instruments, often adapting tools from watch makers, jewelers and even barbers, that he thought could be used in dentistry. Fauchard introduced dental fillings as treatment for dental cavities. He asserted that sugar derivate acids like tartaric acid were responsible for dental decay, and also suggested that tumors surrounding the teeth, in the gums, could appear in the later stages of tooth decay. Fauchard was the pioneer of dental prosthesis, and he discovered many methods to replace lost teeth. He suggested that
