OMG. Sorry that happened to you. Doesn't sound like any fun. I remember one time one of my co-workers and I were out to lunch and I bit into a sandwich and the crown on my front tooth came off. I was mortified. Luckily, it was just my friend and I and not a whole group of people, and especially lucky, I didn't swallow the dumb thing. Stuck it back on, called the dentist who said he was just on the way out to play golf. I told him I thought he could wait a little while and fix my tooth. He was nice about, glued it back on and I haven't had any trouble since, thank Heavens.
