Although this form of one or another form already exists in dentistry from the primitive human age, painless tooth extraction was not available until the 1830s. At the beginning, the teeth were removed with a hard rocking chisel and mallet. Thousands of years later, chisels and mallet methods were abandoned in favor of tweezers during the peak of the great Greek and Roman civilizations.
In the 1890s, a British chemist began to try nitrous oxide as an analgesic, noting its most famous side effect, laughing. He created the popular nickname "joke" for narcotics. For the next 50 years, natural gas has become very popular. In 1863, the combination of gas and oxygen became a major part of surgery.
Shortly after nitrous oxide was applied, local anesthetics were developed. Just before the twentieth century, cocaine was used, but once the characteristics of addiction were identified, a search for suitable alternatives began. Many alternatives were in the form of synthetic cocaine, but it was not until 1905 that German chemists discovered procaine (what he called Novocain) for success. This anesthetic is very popular among dental professionals and the public feels comfortable in "painless dental" voices.
