Millions of Americans cannot find or afford a dentist, and FRONTLINE teams with the Center for Public Integrity to ask why. The film opens with the case of a woman who died from an untreated tooth infection, then widens into an investigation of dental corporations, private equity ownership, and the business incentives that shape which patients get treated and how. Interviews with dentists, former employees, and families follow children suffering preventable decay because routine care was out of reach, alongside examinations of Medicaid reimbursement gaps and corporate dental chains accused of pushing unnecessary procedures to hit revenue targets. Reporters trace how ownership structures obscure who actually controls clinical decisions, and how oversight has failed to keep pace with the industry's consolidation. The film treats dental health as a case study in what happens when a basic medical need gets run like any other retail business, with real patients absorbing the cost of that arrangement.
