There is a cavity epidemic among preschoolers in this country. According to the CDC, for the first time in 40 years tooth decay is on the rise. In fact, it is not unusual for young kids at all income levels to have cavities in half or even more of their teeth. We look at challenges in pediatric dentistry and what you can do to prevent tooth decay with the University of Iowa head of pediatric dentistry, Dr. Rebecca Slayton.
