I used to crunch ice, which is a HUGE no-no/ can crack your teeth. Consequently, I have several crowns on back molars. Other than paying for them (and wishing I hadn't cracked my teeth in the first place), "it's OK." Really! It wasn't excessively painful or anything.
I have two gold ones and a porcelain (white) one. Hopefully that's it. I've quit crunching ice, but still tend to clench/ grind my teeth ...
(I do wear an oral 'appliance' at night to prevent some damage.)
