More people are heading to the emergency room with dental problems. The increase people going to the emergency room with dental problems is largely driven by young adults who do not have dental benefits, according to the ADA Health Policy Resources Center. The number of dental emergency room visits in the U.S. increased from 1.1 million in 2000 to 2.1 million in 2010, according to the National Hospital Ambulatory Medical Care Survey. The survey also showed dental ER visits as a percent of total ER visits increasing from 1.06 percent in 2000 to 1.65 percent in 2010—a change HPRC cites as statistically significant.
