“Isaac Gagnon stepped off the school bus sobbing last October and opened his mouth to show his mother where it hurt. A dentist’s statement in his backpack showed he had received two pulpotomies, or baby root canals, along with the crowns and 10 X-rays — all while he was at school. ‘I was absolutely horrified,’ said Gagnon.’I never gave them permission to drill into my son’s mouth. They did it for profit.’ [Dental management-services companies like ReachOut] have been riding a boom in Medicaid outlays on dentistry, which rose 63 percent to $7.4 billion between 2007 and 2010, outstripping the 4.9 percent growth in other dental spending.”
