Laughing Gas, Now We're Getting to a Happy Ending

Laughing gas was discovered by an English chemist, Joseph Priestley in 1772. No one used it as an anesthetic until 1844 when Horace Wells inhaled the gas while operating on himself. The very next day he sat down in his own operating chair and inhaled theGas until he lost consciousness then a colleague extracted a wisdom tooth. They joined back up with the ADA to form the National Dental Association in 1897. And finally in 1922, when all was forgiven, the ADA became the ADA again. That's cannot imagine the 30 years of bullshit that went on to get it back there.
