One of my two ceramic teeth fell out. Ironically this happened as I brushed my teeth this morning. But it has been loose for weeks now, so it didn't come as a shock. I've even set aside a bit of money to get it fixed. You'd think gluing a tooth back on would take five minutes, but it will probably take days and cost a lot of money. Anyway, this was a synthetic tooth so there should be no immediate problems except looking ugly and speaking funny.
