The high suicide rate among dentists is one of the darker clouds in the industry. By asking this question, the interviewers are not only trying to ensure that you're aware of this fact, but they're also trying to ensure that you have a high level of emotional intelligence (EQ). From their website, 'emotional intelligence - that indefinable something more that people expect in a doctor, such as being ethical, sympathetic, and caring in their relationships, as well as comfortable with themselves and others in their environment.'
Show that you are fully prepared to handle the pressures associated with a career in dentistry. Discuss the ways you cope with the stress and maintain a work /life balance. This could include meditation, working out at the gym, going for a hike now and then, or diving into a hobby.
