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 void 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 and will be away on business for the next week. The patient asks whether there is anything the dentist can do quickly to make him comfortable over the next week until he returns from his trip.
What can be done?
