DentaQuest Data Breach: Lawsuit Investigation

DentaQuest Security Incident: What Happened?
DentaQuest, a nationwide dental and vision insurance provider, has experienced a data breach involving the sensitive information of potentially millions of Americans.
According to a notice posted to its website on July 16, 2026, DentaQuest detected on May 20, 2026 that unauthorized individuals had accessed certain data on its computer network. The company eventually determined following an investigation with independent cybersecurity experts that the breach occurred between May 17, 2026 and May 20, 2026, resulting in the acquisition and publishing of information online.
The online notice states that the information affected by the DentaQuest data breach included names, addresses, Social Security numbers, member identification numbers, Medicaid and Medicare numbers, as well as dental or vision health information, including provider names, diagnoses, treatments and billing information.
DentaQuest began sending affected individuals notice of the data breach, a sample of which can be seen below, on July 17, 2026.
Though the total count has not been publicly disclosed, reports submitted to state government offices have preliminarily indicated that the body of affected individuals includes approximately 522,000 Massachusetts residents, 3,973,000 Texas residents and 17,100 South Carolina residents.
