A dentist's office in Fukuoka, southern Japan, has people streaming in around the clock to be relieved of their pain or to improve their smile. Some of the patients include: a man who lost 3 of his front teeth in a fight back in high school; an older man who has had dentures since he was in his 40's; and a university student who says that getting her teeth fixed gave her a more positive outlook on life. Each chip, crack, cavity and missing tooth has a story behind it. For 3 days, we hear about some of the drama in these patients' lives.
