Adult Medicaid dental coverage is optional, creating a 50-state patchwork

While Medicaid is required to cover dental care for children, adult dental coverage is entirely optional for states. As a result, the dental benefits available to a low-income adult depend entirely on which state they live in. Some states offer comprehensive coverage. Others cover only emergency extractions. A few cover almost nothing at all. A Medicaid recipient who moves from a state with full dental coverage to one with emergency-only coverage loses access to cleanings, fillings, and root canals overnight. The human cost is staggering. Adults on Medicaid in states with limited dental coverage face a cruel choice: live with dental pain, pay out of pocket with money they do not have, or wait until the problem becomes an emergency that qualifies for extraction. The result is widespread tooth loss among low-income Americans. By age 65, adults in the lowest income bracket have lost an average of 25% more teeth than higher-income adults. Missing teeth affect nutrition, employment prospects, and self-esteem. Employers admit in surveys that they judge candidates partly on their smile. The structural reason this persists is that state budgets are perpetually strained, and adult dental Medicaid is one of the first line items cut during fiscal downturns. Dental coverage was trimmed or eliminated in many states during the 2008 recession and never fully restored. Federal legislation to mandate adult dental Medicaid coverage has been introduced repeatedly but never passed, because the CBO scores it as a significant new federal expense and there is no powerful constituency lobbying for it.
