A 50-year-old man comes to the office for an emergency visit complaining that an old, large silver filling fell out of his tooth this morning while he was eating breakfast. He can feel the vold in his tooth and can
see it when he opens his mouth and looks in the mirror, and the tooth is sensitive to cold. His concern is
that he does not have time to stay for a long appointment today as he has a flight to catch in a few hours

can do quickly to make him comfortable over the next week until he returns from his trip. What can be
done?
