I seem to have a bit of a problem. I have had a crown on my tooth for around 5 years, and last night I ran into a bit of trouble, one thing led to another, and I seem to have swallowed my crown, this was about 12 hours ago. I am afraid to go to the toilet and am afraid to smile. What will happen? Should I go to an emergency room? Will I digest it? if I don’t will it damage me on the way out? What can I expect?
