I get to join the club now, couple hours ago I chipped around of quarter of one of my front teeth straight off after a snag. Got to take an early trip to the dentist tomorrow morning.
Please change your strings when they get old and grippy.
Edit: It DID leave a nice ding in the SS ring of the bimetal I was using too, surrounded by some nice teeth fragments / dust. I’d definitely say the ss won though.
