We caught up with Dr. Careswell, who tells us that there was even more to that day than what you see on TV. "Mary never spent a lot of time at the dentist as a child, so she didn't know what to expect," says Dr. Careswell, who sat down with Mary before cameras were rolling to make sure she was comfortable. "The original injury, when she lost her front tooth and broke the tooth beside it, was really traumatic for her. For her, to think about dental work was just overwhelming. These fears were holding her back from pursuing the dentistry that she needed for many years."
