I have re-adopted my night guard with nearly religious zealotry, thanks. I had gone a couple of months without it, and I'm pretty sure that this was the result. I'd never heard the term "bruxe" before - I see "bruxism" is what I'm doing; thanks for the lead.
Right now I'm happy to have a crown which is shaped like a real tooth, glued in there permanently, and unlikely to end up in my bacon, like the last one did. I like my bacon crunchy, but not that crunchy.
