He encouraged tooth transplantation from animals over humans, stating the latter to be "inhumane" and "attended with too many difficulties". Pierre Fauchard shared his experience in tooth transplantation in the acclaimed "Le Chirurgien Dentiste" (""The Surgeon Dentist""), published in 1728. In it, he detailed transplanting a canine from a soldier to a Captain in an army. The donor tooth was too wide and long for the Captain and Fauchard resorted to reducing its size to fit into the receiver's socket. This resulted in a cavity on the tooth which Fauchard filled once the tooth stabilized. The filling was removed the next day however, as it caused extreme pain. Fauchard saw the patient eight years later who had lost the donor tooth by then but the Captain insisted that the tooth had lasted him six years before being extracted due to caries. Philipp Pfaff, credited as Germany's first "state-appointed dentist", published "Abhandlung von den Zähnen des menschlichen Körpers und deren Krankheiten", (Treatise on The Teeth of the Human Body and Their Diseases) in 1756. He was not fond of tooth transplantation from corpses but emphasized the importance of preserving periodontal ligaments of the transplanted tooth and sealing the apical foramen with lead or wax. John Hunter documented successful transplantation between humans in 1772, at the peak of the procedure's popularity, stating that it is "without great difficulty, Nature assisting the operation, if it is done in such a way she can assist". Hunter appreciated that the tooth transplanted should ideally be smaller than the socket, and if not, should be adjusted to fit the socket. Hunter is guilty however, of not acknowledging the significance of tooth transplantation in spreading syphilis to seven of his patients following the procedure. Benjamin Bell wrote in 1785 on tooth transplanting in his book, "A system of surgery (volume 5)," pp. 76, on how the transplanted tooth must be "free from scurvy and the lues venera" thereby appreciating the significance of the procedure in the transmission of various infections. Following Nicholas Dubois de Chemant's development of "mineral paste dentures", which he patented in 1788, allotransplantation was gradually replaced by dentures that at that time were claimed to not decay in the mouth. Towards 1950, autotransplantation began to appear in dental literature, renewing interest in tooth transplantation.
