Nitrous oxide has been used for anaesthesia in dentistry since December 1844, where Horace Wells made the first 12–15 dental operations with the gas in Hartford. Its debut as a generally accepted method, however, came in 1863, when Gardner Quincy Colton introduced it more broadly at all the Colton Dental Association clinics, that he founded in New Haven and New York City. Hospitals administer nitrous oxide as one of the anaesthetic drugs delivered by anaesthetic machines. Nitrous oxide is a weak general anaesthetic, and so is generally not used alone in general anaesthesia. In general anaesthesia it is used as a carrier gas with oxygen for more powerful general anaesthetic drugs.Medium size empty blue coloured cylinder with rounded base and painted white neck once containing Nitrous Oxide.

The advent of anaesthesia posed immediate problems for the oral surgeons and dentists who were used to operating on awake patients with intact airway reflexes. Early anaesthetics were very light and often created an uncooperative patient. Dentists were quick to complain they had trouble opening the mouth quickly enough and dental props soon made an appearance. Gags and tongue depressors proliferated, all initially devised to improve surgical and anaesthetic access, not to protect the airway. Other instruments for opening the jaws included the somewhat fearsome devices known as mouth openers. Heister's mouth opener was incorporated in anaesthetic practice but was not designed for this purpose. Lorenz Heister (1983 - 1758) used his device for mouth inspection and for operations on the palate, tonsils and teeth in the pre-anaesthesia era. He was not impressed with the way it was used by others in his life time and believed that it overstretched the jaw when used inappropriately. Despite its apparent brutality, the Heister mouth gag was still advertised for sale in 1983 and its useful mechanism has been incorporated into modern surgical retractors. This Heister heavy patterned mouth opener was acquired from an Italian Army medical unit at Tobruk in 1941 and donated to the museum in 1946.Scissor-like metal device with a screw mechanism at the top which allows for the open or closed position to be locked.heister, lorenz, mouth opener, gag, heavy patterned
