DentaQuest data breach

Clerk's notes

DentaQuest, a major administrator of dental benefits, formally reported a cybersecurity incident to the Vermont Attorney General on September 28, 2026. As a company that manages oral health coverage for millions, DentaQuest handles extensive volumes of sensitive personal and health information.

The reported breach exposed critical personal identifiers and health-related data. The compromised information includes 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. Such comprehensive data allows for potential identity theft and various forms of fraud, which can have long-lasting consequences for affected individuals.

Companies like DentaQuest are legally obligated by regulations such as HIPAA to protect electronic protected health information. The occurrence of a data breach involving such sensitive categories of data raises questions about the security protocols and safeguards that were in place to prevent unauthorized access to these records.

If you have received an official data breach notification letter from DentaQuest, it confirms that your confidential information was part of this security incident.
