Preschool Mouths: Dental Disaster Zones - ABC News: Just this morning, Dr. Jonathan D. Shenkin, a pediatric dentist in [fluoridated] Augusta, Maine, found six small cavities between the teeth of a 4-year-old girl during her first-ever appointment with a dentist, who should have been seen by her first birthday. The girl’s mother was at a loss to account for all the decay in her daughter’s mouth, telling Shenkin that she thought she had her children doing everything right: “We don’t drink soda. They brush their teeth twice a day.”
