The beginnings of dentistry in the United States came in the 1630s with the settlers of the Massachusetts Bay Colony, who were accompanied by barber-surgeons. One of the first dentists in America was English surgeon and dentist John Baker, who settled in Boston in 1763. Other immigrants to follow included Robert Wooffendale, who emigrated from England in 1766 and practiced in New York City, and Jacques Gardette, who moved from France in 1778, eventually settling in Philadelphia. In early colonial America, dental care was also rendered by artisans such as ivory turners. One such artisan was Isaac Greenwood, who began practicing dentistry in 1779 and is considered to be the first American-born dentist. Four of his six sons became dentists. The most prominent, John Greenwood, served as George Washington’s dentist. Other craftsmen performed a variety of dental services, the most well known being Paul Revere, who practiced dentistry for seven years in Boston. The first book on dentistry to be published in the United States appeared in 1801 and was written by Richard Cortland Skinner, a young immigrant from England.

By the first quarter of the 19th century, the United States had become the leading centre in the world for dental developments. From 1839 to 1840 three major events in dental practice facilitated the establishment of dentistry as a true profession. In 1839 the first dental journal, the American Journal of Dental Science, was launched; in 1840 the first dental school, the Baltimore College of Dental Surgery, was established; and in 1840 the first national society of dentists, the American Society of Dental Surgeons, was founded in New York City.

Great new advances in the field came about very quickly at this time. In 1844 American dentist Horace Wells discovered the anesthetic properties of nitrous oxide, which he promptly began using while performing tooth extractions. In 1846 another American dentist, William Thomas Green Morton of Boston, successfully demonstrated in public the effectiveness of ether anesthesia. Because Wells’s own public demonstration prior to Morton’s was unsuccessful, a controversy erupted over who deserved credit for the remarkable discovery of anesthesia. However, the two major health organizations in the United States—the American Dental Association and the American Medical Association—voted in favour of Horace Wells in 1864 and 1870, respectively.

Numerous advances in equipment, materials, and techniques followed one upon the other. In 1864 vulcanized rubber was introduced as a substitute for difficult and costly gold dentures, allowing dentists to supply dentures at a lower cost. The introduction of a foot-treadle drill in 1871 by American dentist James Beall Morrison of Missouri supplanted awkward handheld drills and gave dentists the ability to create intricate and aesthetic restorations.

New dental schools were being established in many parts of the nation. The first dental school to be affiliated with a university was that at Harvard University in 1867. Nevertheless, most dentists were still being trained by a system of preceptorship with an established dentist. The beginning of licensure in the United States came about in 1868, with the states of New York, Ohio, and Kentucky leading the way.

In 1890 American dentist Willoughby Dayton Miller published The Micro-organisms of the Human Mouth, in which he proposed the theory that dental caries were the result of bacterial activity. Miller’s publication led to a tremendous wave of interest in oral hygiene. In 1913 American dentist Alfred C. Fones opened the Fones Clinic for Dental Hygienists in Bridgeport, Conn., the first establishment for formal training, at the college level, of dental hygienists.

Dentistry in 19th-century Europe

In the 19th century in Europe, several technological developments were taking place. Chief among these developments was the introduction of porcelain teeth for dentures by Italian dentist Giuseppangelo Fonzi. Fonzi’s porcelain teeth provided an appealing alternative to traditional tooth replacement with the repugnant teeth from corpses.

In Britain, dentistry was also coming of age. In 1856 English dentist Sir John Tomes led the formation of the first dental organization in England, the Odontological Society. It was through the activity of this group that the Royal Dental Hospital of London was established in 1858. In opposition to the Odontological Society, a group of dental professionals formed the College of Dentists of England in 1857, seeking independence from the Royal College of Surgeons, which influenced the proceedings of the Odontological Society. The College of Dentists of England established the Metropolitan School of Dental Science, the forerunner of the University College Hospital Dental School. In 1878 the passage of the Dentists Act, which put dentistry under the General Medical Council, led to the authorization and formation of the Dental Register, a precursor to ultimate licensure that prescribed a curriculum for the training of dentists. This system remained in effect until 1921, when new laws provided for stricter requirements for examination and licensure. In 1880 the British Dental Association was established; it remains the most important dental organization in the United Kingdom.
