"Impressions"...is this still a thing?
The dentist (or orthodontist) would fill a metal dish with this pink putty, and they'd jam it into your mouth, pressing it against your teeth. The idea was it made an impression that can be used to create a mold of your teeth, but that goop had a tendency of rolling out of the dish, down towards the throat. I gagged on that goop every time! 😝
