Could you clean teeth for a living? Looks simple right? It's not! This week's guest, Dorothy Smith, demystifies a profession we have all experienced up-close and personal (after all, their hands are inside your mouth for about 30 minutes). Having done this for 28 years, Dorothy tells us what is required to be trained and certified in this field, how posture and ergonomics play into this physically taxing job, how she was a little grossed out a few times, and what she does to make her patients comfortable. But beyond all that, Dorothy also shares how she overcame an accident that halted her life for about a year and left her with a badly injured dominant hand. However, Dorothy explains, "I've always been stubborn," and that stubborn streak drove her to emerge from a dark time to pursue - and obtain - a nursing degree that she hopes will soon position her to work in a hospital operating room. A surprising career shift? Not at all, since Dorothy's favorite TV show as a young girl was the surgery channel!
