The Patient Protection and Affordable Care Act may have mandated dental insurance for children, but the new law does not address coverage for adults.

In fact, experts say it could actually significantly disrupt the dental benefits market if employers drop coverage for their workers or workers opt out of duplicative plans for themselves to pay for their children's benefits.

Meanwhile, charitable oral care is on the rise to address the continued need for adults without dental insurance or access to dentists in underserved markets, as well as children whose families—for whatever reason—don't take advantage of dental insurance.
