It’s Just Scary: The Dentist’s Foot Engine
By Sean O'Hara
I visited the local science museum recently and ran across this circa-1890, dentist’s “foot engine.” I realize now why people back in the 1800s had jacked up teeth” they didn’t want to go stare this thing down.
Basically, the drill is attached to one end of a rotary cable, which in turn is attached to the wheel via gearing and a belt. The dentist (or his assistant) mashes the pedal up and down to spin the drill.
I always thought the new-fangled super-high-rpm drills sounded like death, but the slow rickety noise this thing must have made must be way, way worse. So call me a sissy, but I’d probably have messed up teeth, too, if this was the only other option.

I just looked up that Einhorn synthesized Novocaine in 1905, so there is a 15 year window there where I definitely wouldn’t have wanted to get a filling.

On the other hand, Wikipedia says that prior to the discovery and synthesis of Novocaine, cocaine was the most commonly used anesthetic!!

The US Army still has these around for backup when the power fails or is unavailable.

I’ve gotten a few fillings without novacaine, and it’s actually not as bad as you’d think. Just last week my wife went through the same. She didn’t crush my hand too badly, which confirms my “it’s not that bad” declaration.
Still, I would not wanna have any work done via a foot-powered drill.
Also, is it me, or does that chair look like an execution chair?

Actually, cocaine is an excellent local anesthetic, and is probably what should be used. Lidocaine’s pretty common nowadays.
No, it doesn’t look like an execution chair.

[...] can afford it. You might even be able to find a foot-powered dental drill. These are now considered museum pieces, except in the Third World, where they are still in limited [...]
