DentaQuest Reports 2026 Data Breach Exposing Personal Data

DentaQuest, a company that administers dental benefits and manages oral health coverage for millions, reported a cybersecurity incident to the Vermont Attorney General on September 28, 2026. This notification confirms an unauthorized compromise of its network infrastructure, impacting individuals whose information it maintains.

The compromised data categories include Full Name, Date of Birth, Social Security Number, Health Insurance ID Number, Dental Treatment History, Diagnosis and Provider Information, Billing and Claims Records, and Home Address. When such a wide range of sensitive personal and health-related data is exposed, individuals face elevated risks of identity theft, various forms of fraud, and other long-term financial complications.
