Crown Fell Off
This happens quite often. Usually the result of chewing on something sticky which loosens the crown. Once loosened the crown will fall out. Well, what to do? If possible replace it without any cement (glue). Just put it back on the tooth and press or bite down. It should reseat. Call the office to have it evaluated and recemented. If it doesn’t stay on the tooth then leave it off and call the office. This is not truly a emergency.
