Everybody was supposed to find oral surgeons in their first year and leave jars with them to collect teeth to use for our endodontic training. We would do our root canals on real, extracted teeth, including for our board exams.
There were quite a few students who found themselves in quite the bind without enough good teeth, so of course they purchased them from some random guy on the internet in Egypt.
When they were shipped, the teeth would be concealed as a piece of abstract art with the teeth glued onto a canvas to make flower designs. And they were packaged in many layers so as to avoid detection throughout the import process. It was the sketchiest thing ever, and I’m glad I never had to purchase any human remains.
