Dental History Timeline
Ancient origins
7000 BC - Evidence of ancient dentistry has recently been found in a Neolithic graveyard in ancient Pakistan. Teeth dating from around 7000 to 5500 BC show evidence of holes from dental drills. The teeth were found in people of the Indus Valley Civilization.
5000 BC - A Sumerian text of this date describes “tooth worms” as the cause of dental decay. Evidence of this belief has also been found in ancient India, Egypt, Japan, and China. The legend of the worm is also found in the writings of Homer, and as late as the 1300's AD the surgeon Guy de Chauliac still promoted the belief that worms cause tooth decay.
2600 BC - Death of Hesy-Re, an Egyptian scribe, often called the first “dentist.” An inscription on his tomb includes the title “the greatest of those who deal with teeth, and of physicians.” This is the earliest known reference to a person identified as a dental practitioner.
1800 BC - In the 18th century BC, the Code of Hammurabi referenced dental extraction twice as it related to punishment. Examination of the remains of some ancient Egyptians and Greco-Romans reveals early attempts at dental prosthetics and surgery.
1700-1550 BC - An Egyptian text, the Ebers Papyrus, refers to diseases of the teeth and various toothache remedies.
500-300 BC - Hippocrates and Aristotle write about dentistry, including the eruption pattern of teeth, treating decayed teeth and gum disease, extracting teeth with forceps, and using wires to stabilize loose teeth and fractured jaws.
100 BC - Celsus, a Roman medical writer, writes extensively in his important compendium of medicine on oral hygiene, stabilization of loose teeth, and treatments for toothache, teething pain, and jaw fractures.
166-201 AD - The Etruscans practice dental prosthetics using gold crowns and fixed bridgework.
Middle ages & The Renaissance
500-1000 - During the Early Middle Ages in Europe medicine, surgery, and dentistry, are generally practiced by monks, the most educated people of the period.
700 - A medical text in China mentions the use of “silver paste,” a type of amalgam.
1130-1163 - A series of Papal edicts prohibit monks from performing any type of surgery, bloodletting or tooth extraction. Barbers often assisted monks in their surgical ministry because they visited monasteries to shave the heads of monks and the tools of the barber trade—sharp knives and razors—were useful for surgery. After the edicts, barbers assume the monks’ surgical duties: bloodletting, lancing abscesses, extracting teeth, etc.
1210 - A Guild of Barbers is established in France. Barbers eventually evolve into two groups: surgeons who were educated and trained to perform complex surgical operations; and lay barbers, or barber-surgeons, who performed more routine hygienic services including shaving, bleeding and tooth extraction.
1400's - A series of royal decrees in France prohibit lay barbers from practicing all surgical procedures except bleeding, cupping, leeching, and extracting teeth.
1530 - The Little Medicinal Book for All Kinds of Diseases and Infirmities of the Teeth (Artzney Buchlein), the first book devoted entirely to dentistry, is published in Germany. Written for barbers and surgeons who treat the mouth, it covers practical topics such as oral hygiene, tooth extraction, drilling teeth, and placement of gold fillings.
1563 - Batholomew Eusttachius published the first accurate book on dental anatomy, 'Libellus de dentibus'
1575 - In France Ambrose Pare, known as the Father of Surgery, publishes his Complete Works. This includes practical information about dentistry such as tooth extraction and the treatment of tooth decay and jaw fractures.
1683 - Antony van Leeuwenhoek identified oral bacteria using a microscope.
1685 - The first dental textbook written in English "The Operator for the Teeth" written by Charles Allen.
18th Century
1746 - Claude Mouton describes a gold crown and post to be retained in the root canal. He also recommends white enameling for gold crowns for a more esthetic appearance.
1760 - John Baker, the earliest medically-trained dentist to practice in America, immigrates from England and sets up practice.
1764 - First lectures on the teeth at the Royal College of Surgeons, Edinburgh by James Rae.
1768 - 1770 - Paul Revere places advertisements in a Boston newspaper offering his services as a dentist.

19th Century
1801 - Richard C. Skinner writes the Treatise on the Human Teeth, the first dental book published in America.
1820 - Claudius Ash established his dental manufacturing company in London.
1825 - Samuel Stockton begins commercial manufacture of porcelain teeth. His S.S. White Dental Manufacturing Company establishes and dominates the dental supply market throughout the 19th century.
1830’s-1890’s The 'Amalgam War' conflict. The Crawcours (two brothers from France) introduce amalgam filling material in the United States under the name Royal Mineral Succedaneum. The brothers are charlatans whose unscrupulous methods spark the “amalgam wars,” a bitter controversy within the dental profession
over the use of amalgam fillings.
1831 - James Snell designed the first reclining dental chair.
1839 - The American Journal of Dental Science, the world’s first dental journal, begins publication.
1839 - Charles Goodyear invents the vulcanization process for hardening rubber. The resulting Vulcanite, an inexpensive material easily molded to the mouth, makes an excellent base for false teeth, and is soon adopted for use by dentists. In 1864 the molding process for vulcanite dentures is patented, but the dental profession fights the onerous licensing fees for the next twenty-five years.
1843 - First British Dental Journal was published.
1844 - Horace Wells, a Connecticut dentist, discovers that nitrous oxide can be used as an anesthesia and successfully uses it to conduct several extractions in his private practice. He conducts the first public demonstration of its use as an anesthetic in 1845 but the demonstration is generally considered a failure after the patient cries out during the operation. In 1846, another dentist (and a student of Wells), William Morton, takes credit for the discovery when he conducts the first successful public demonstration of the use of ether as an anesthesia for surgery. Crawford Long, a physician, later claims he used ether as an anesthetic in an operation as early as 1842, but he did not publish his work.
1855 - Robert Arthur originates the cohesive gold foil method allowing dentists to insert gold into a cavity with minimal pressure. The foil is fabricated by annealing, a process of passing gold through a flame making it soft and malleable.
1858 - Dental Hospital of London opened, the first clinical training establishment for dentists in Britain.
1859 - Twenty-six dentists meet in Niagara Falls, New York, and form the American Dental Association.
1864 - Sanford C. Barnum, develops the rubber dam, a simple device made of a piece of elastic rubber fitted over a tooth by means of weights, which solves the problem of isolating a tooth from the oral cavity.
1869 - Dr. Robert Tanner Freeman, graduating from Harvard University Dental School, becomes the first African-American to earn a dental degree.
1871 - A tooth coloured filling material, silicate cement, was introduced.
1871 - James B. Morrison patents the first commercially manufactured foot-treadle dental engine. Morrison’s inexpensive, mechanized tool supplies dental burs with enough speed to cut enamel and dentin smoothly and quickly, revolutionizing the practice of dentistry.
1871 - The American George F. Green receives a patent for the first electric dental engine, a self-contained motor and handpiece.
1877 - The Wilkerson chair, the first pump-type hydraulic dental chair, is introduced.
1880’s - The collapsible metal tube revolutionizes toothpaste manufacturing and marketing. Dentifrice had been available only in liquid or powder form, usually made by individual dentists, and sold in bottles, porcelain pots, or paper boxes. Tube toothpaste, in contrast, is mass-produced in factories, mass-marketed, and sold nation-wide. In twenty years, it becomes the norm.
1880 - British Dental Association founded.
1884 - Cocaine was introduced as a local anaesthetic by Carl Koller
1887 - Stowe & Eddy Dental Laboratory, the first successful industrial-type laboratory in the U.S., opens in Boston, marking the ascendancy of the modern commercial dental laboratory. The earliest known dental laboratory in the U.S. was Sutton & Raynor which opened in New York City around 1854.
1890 - Willoughby Miller an American dentist in Germany, notes the microbial basis of dental decay in his book Micro-Organisms of the Human Mouth. This generates an unprecedented interest in oral hygiene and starts a world-wide movement to promote regular toothbrushing and flossing.
1895 - Wilhelm Roentgen (1845 - 1923),
a German physicist, discovers the x-ray.
In 1896 prominent New Orleans
dentist, C. Edmond Kells, takes the
first dental x-ray of a living person
in the U.S.
1896 - Greene Vardiman Black, a leading reformer and educator of dentistry establishes the principles of cavity preparation. In 1908 (see below) he publishes his two-volume treatise: Operative Dentistry .
1899 - Edward Hartley Angle classifies the various forms of malocclusion. Credited with making orthodontics a dental specialty, Angle also establishes the first school of orthodontics (Angle School of Orthodontia in St. Louis, 1900).
20th Century
1900 - Federation Dentaire Internationale (FDI) is founded.
1901- Novocaine was introduced as a local anaesthetic by a German chemist, Alfred Einhorn. In 1905 Einhorn formulates the local anesthetic procain, later marketed under the trade name Novocain.
1903 - Charles Land devises the porcelain jacket crown.
1907 - William Taggart invents a “lost wax” casting machine, allowing dentists to make precision cast fillings.
1908 - G. V. Black publishes his monumental two-volume treatise Operative Dentistry, which remains the essential clinical dental text for fifty years. Black later develops techniques for filling teeth, standardizes operative procedures and instrumentation, develops an improved amalgam, and pioneers the use of visual aids for teaching dentistry.
1913 - Alfred C. Fones opens the Fones Clinic For Dental Hygienists in Bridgeport, Connecticut, the world’s first oral hygiene school. Most of the twenty-seven women graduates of the first class are employed by the Bridgeport Board of Education to clean the teeth of school children. The greatly reduced incidence of caries among these children gives impetus to the dental hygienist movement. Dr. Fones, first to use the term “dental hygienist,” becomes known as the Father of Dental Hygiene.
1924 - American Dental Assistants Association is founded by Juliette Southard and her female colleagues. Female dental assistants were first hired in the 19th century when “Lady in Attendance” signs were routinely seen in the windows of dental offices. Their duties included chair-side assistance, instrument cleaning, inventory, appointments, bookkeeping, and reception.
1930–1943 - Frederick S. McKay, a Colorado dentist, is convinced that brown stains (mottling) on his patients’ teeth are related to their water supply. McKay’s research verifies that drinking water with high levels of naturally occurring fluoride is associated with low dental caries and a high degree of mottled enamel. By the early 1940s, H. Trendley Dean determines the ideal level of fluoride in drinking water to substantially reduce decay without mottling.
1938 - The nylon toothbrush, the first made with synthetic bristles, appears on the market.
1937 - Alvin Strock inserts the first Vitallium dental screw implant. Vitallium, the first successful biocompatible implant metal, had been developed a year earlier by Charles Venable, an orthopedic surgeon.
1940’s - 22,000 dentists serve in World War II.
1945 - The water fluoridation era begins when the cities of Newburgh, New York, and Grand Rapids, Michigan, add sodium fluoride to their public water systems.
