result of living in indiana too long?

is this from living here too long, or, more likely, another "symptom" of pregnancy. well, although it would seem to be the first, really it's more likely the second. i ALWAYS have something major happen to my teeth when i'm pregnant. i was thinking i was going to get away with nothing happening this time. SILLY ME. i had noticed that this crown was a little loose and i was chewing gum when it just popped out. i'm hoping it just needs to be re-cemented but i'm not feeling much up there to cement it to. talk about embarrassing! Drrr!
