Sanders and Khanna have introduced legislation that would establish a 5% wealth tax on billionaires to fund a $4.4 trillion expansion of social programs, including Medicare dental, vision, and hearing coverage and reversal of recent Medicaid cuts.

This is a direct counterattack on Trump-era cuts enacted under the One Big Beautiful Bill Act. While the wealth tax mechanism faces steep political headwinds in a GOP-controlled Congress, the dental expansion proposal captures momentum from states that have unilaterally expanded Medicaid adult dental coverage in recent years—including Tennessee, which now covers roughly 600,000 low-income adults. The bill signals Democratic priorities heading into budget negotiations and establishes a legislative marker for future negotiations. For dental practices serving Medicaid patients, this represents a potential shift in payer landscape; Medicare dental coverage would create an entirely new revenue stream for practices willing to contract with CMS.

The implications are significant but timeline-dependent. A wealth tax faces constitutional and political challenges and will not advance in the current Congress. However, the dental expansion component could resurface in future reconciliation bills or as a standalone policy proposal if Democrats regain legislative power. Dental practice owners should monitor state-level Medicaid expansions separately, as those are moving now regardless of federal action. The real opportunity lies in preparing infrastructure (credentialing, fee schedules, patient management systems) for potential Medicare participation if coverage expands.

What to watch: Congressional budget negotiations over the next 12 months and state-level Medicaid coverage decisions in 2026, which will indicate real near-term revenue shifts for dental practices before any federal action materializes.
