Women who weave or spin can get grooves in their front teeth where they bite off the threads. I would look for a possible occupational cause (perhaps a mouth guard on a helmet or balancing the edge of a shield for young warriors?) as another cause.
Anybody else remember all the jumping to conclusions in The Motel of the Mysteries?
"The Motel of the Mysteries"
Hilarious book, but so true! I had an archeologist tell me once that they operate in the realm of guess and speculation, not always provable fact.
Good point. These people weren't as stupid as the elitist academia makes them out to be. Grinding down your teeth for a show of some kind of prowess could be a death sentence back then.
Grinding them down during necessary tasks for the tribe's survival is another story.
that is a great book!
