The study from University of Iowa researchers looked at California, which decided to end adult dental coverage under Medicaid in mid-2009. Some 3.5 million low-income adults in the Golden State lost dental benefits.
The researchers found those adults made more than 1,800 additional visits annually to hospital emergency departments for dental care after losing the benefit. In all, California spent $2.9 million each year in Medicaid costs for dental care in emergency departments, up from $1.6 million before the state eliminated the adult dental care benefit. That's a 68 percent increase in costs, when factoring inflation.
