From the October 9, 1902 Brooklyn Daily Eagle:

“Cleveland–Frank Buettner, a well known contractor of this city, died early to-day as the result of an operation performed to remove a set of false teeth which it was supposed he had swallowed while asleep Monday night. Just as his esophagus had been opened its entire length a relative of Buettner’s rushed into the operating room with the missing set of teeth, which had been found in Buettner’s bed. It was then learned that Buettner was suffering from acute laryngitis. The pain in his throat led him to believe he had swallowed his teeth.”
