History of Dentistry

Dentistry got its start in the Indus Valley of India and Pakistan. This was also the first appearance of dental assistants. The first explanation of causes of tooth decay was the tooth worm, first noted by the Sumerians around 5000 BC. The hypothesis was that tooth decay was the result of a tooth worm.

The idea of the tooth worm has been found in the writings of the ancient Greek philosophers and poets, as well as those of the ancient Indian, Japanese, Egyptian, and Chinese cultures.

The first society which used dental bridges and appliances were the Etruscans.

Until the 16th century, there weren’t dentists and dentistry was practiced by general physicians and barbers. The staple procedure of these early dentists was the extraction, which was used to alleviate pain and halt tooth decay. Over the years, a number of tools were invented for performing this procedure.

In the 20th century, the key was replaced by the forceps, which are still in use today.

In 1723, French surgeon Pierre Fauchard published The Surgery Dentist. He is considered to be the father of modern dentistry because his book was the first to describe a comprehensive system for caring and treating the teeth.

The first dental foot engine was built by John Greenwood. It was made from a foot-powered spinning wheel.

In 1871, George F. Green invented the first electrical dental engine.

1790 was a big year for dentistry, as this was also the year when the first specialized dental chair was invented.

Dentist Horace Wells from Connecticut was the first who discovered that nitrous oxide could be used as anesthesia. After using it with success on several of his patients, he attempted to demonstrate its effects in public.

Charles Land devised the porcelain jacket crown.

In 1905, Alfred Einhord, a German chemist, discovered Novоcain.

In 1938, the first tooth brush with synthetic nylon bristles hit the market.

In 1945, the water fluoridation era began when the cities of Newburgh, NY and Grand Rapid, MI decided to add fluoride to the public water supply. In 1950, the first fluoride toothpastes were marketed.

In 1957, John Borden invented the first high speed electric hand drill.

In 1960s, the first dental lasers were developed and used for soft tissue procedures.

In 1960s the first electric toothbrush was invented.

The 1990s marked the beginning of the era of cosmetic dentistry, with the increased popularity of veneers, bleaching, and dental implants.
