The first recorded use of anesthesia in a medical procedure was performed by a dentist.
On December 11, 1844, Dr. Horace Wells, a dentist from Hartford, Connecticut, demonstrated the use of nitrous oxide—commonly known as laughing gas—for pain-free tooth extraction. After observing its effects at a public demonstration, Wells recognized its medical potential and volunteered to have his own tooth extracted under its influence.
The procedure was successful, marking a turning point in medical history and the beginning of modern anesthesia.
Wells’ discovery paved the way for the widespread use of anesthesia, transforming both dentistry and surgery. His pioneering work laid the foundation for modern pain management, making medical procedures safer, more humane, and more comfortable for patients worldwide.
Despite its impact, Horace Wells’ contribution is often underrecognized outside dentistry. His work proved, for the first time, that pain could be ethically and effectively controlled during medical procedures—forever changing the course of medicine.
