Happened to you with a hamburger too, huh?
I wonder if it was the same molar.
I guess I never gave the tooth guard enough of a chance, but it had a weird taste and I couldn't get used to sleeping with something in my mouth.
I've learned my lesson, though, and once the tooth is fixed I will start using it.
Otherwise my teeth are in pretty good condition, I do take care of them except for the grinding thing, which causes a lot of problems.
