The Dentist’s Office modelled here is based on a turn of the century (1800 - 1900) Dentist’s Office at the Western Development Museum in North Battleford, Saskatchewan, Canada. While dentists were able to offer improvements in service, few anesthetics were available to ease patient's pain. In the early days, equipment was manually operated. Imagine a pedal-operated drill at work in your mouth! Polys 70.
