There are no opening credits although there is an end intertitle part way through. In close up, teeth are cleaned with a brush. Recovery after an apicectomy operation (to remove part of the tooth's root) follows with intertitles indicating the date range; 24 hours, 48 hours, 4 days, 10 days, 2 weeks, 18 days and 4 weeks.
