DentaQuest in 2026
DentaQuest enters the second half of 2026 as one of the largest dental and vision benefits administrators in the United States — and also as the company behind the largest healthcare data breach reported to the US government so far this year. The Massachusetts-based company, now part of Sun Life U.S., has spent nearly a quarter-century building a Medicaid and CHIP-focused dental benefits business that now touches tens of millions of American lives, while more recently expanding into direct patient care through a growing network of oral health centers aimed at rural and underserved communities.
That growth story took a serious hit in 2026 when a cyberattack discovered on May 20 exposed sensitive personal and dental health data belonging to millions of DentaQuest members, an incident that has continued generating fresh disclosures for months afterward. This report compiles the latest verified DentaQuest statistics for 2026 — covering the company’s patient base, revenue, employee headcount, provider network, and the full scope of this year’s data breach — drawing on company disclosures, federal breach filings, and independent business data aggregators current as of August 2026.

The two numbers that define DentaQuest’s 2026 are its $3.2 billion in annual revenue and the scope of the cyberattack that hit the company this spring. Multiple independent business data providers — RocketReach, ZoomInfo, and Datanyze — converge on the same $3.2 billion revenue figure, a rare point of consensus for a privately held company whose other metrics vary considerably depending on the source. DentaQuest describes itself as serving more than 33 million Americans through its dental and vision benefit plans, delivered through a network of roughly 140,000 providers spanning all 50 states, making it one of the largest Medicaid and CHIP dental benefits administrators in the country.
That scale is precisely what made this year’s cybersecurity incident so consequential. A cyberattack discovered on May 20, 2026 — with the unauthorized intrusion itself running from May 17 to May 20 — resulted in the theft of 234 gigabytes of data, and official breach notifications filed with federal regulators put the number of affected individuals at more than 15 million, though some security researchers have cited figures as high as 23.4 million. Whatever the precise final count, healthcare industry trackers have already labeled it the largest healthcare data breach reported to the US government so far in 2026 — a significant reputational and operational challenge for a company whose core business depends on securely handling exactly this kind of sensitive Medicaid and health information.

DentaQuest was founded in 2001 and built its business model around administering dental benefits for Medicaid and CHIP populations — a comparatively unglamorous but structurally durable corner of the insurance industry that has proven resilient even as the broader managed care sector consolidates. The company’s acquisition by Sun Life Financial on June 1, 2022 brought DentaQuest under the umbrella of a major Canadian-headquartered insurance and financial services group, giving it access to substantially deeper capital resources than its earlier, more thinly capitalized history — PitchBook records show the company had raised just $12 million from private equity backers Centerbridge Partners and FdG Associates prior to the Sun Life deal.
That capital backing helps explain how DentaQuest has sustained $3.2 billion in annual revenue in 2026 while simultaneously funding an expansion into direct-care oral health centers — a capital-intensive shift for a company that built its original business purely on benefits administration rather than care delivery. Against named competitors like Aetna, a subsidiary of the much larger CVS Health, and specialized dental plan administrators like LIBERTY Dental Plan and SkyGen, DentaQuest’s scale positions it among the largest dedicated dental benefits companies in the US, even though it remains far smaller than diversified health insurance giants that offer dental coverage as one product among many.

DentaQuest’s membership figures vary meaningfully depending on which source and measurement date is used, ranging from a commonly cited “more than 33 million” Americans across RocketReach and LeadIQ’s company profiles, up to a broader 35-to-37-million range reported by Bitscale.ai’s more recent May 2026 profile. This kind of variance is typical for privately held companies that don’t publish standardized quarterly membership disclosures the way publicly traded insurers do, and it likely reflects differences in how each tracker counts dental-only versus combined dental-and-vision enrollees, or how frequently their underlying data gets refreshed.
There’s also some disagreement in how DentaQuest’s market position gets described: the company’s own materials and most business trackers describe it as the largest Medicaid and CHIP dental benefits administrator in the country, while at least one industry publication covering the 2026 data breach specifically referred to DentaQuest as the “second-largest dental benefits administrator in the U.S.” Regardless of its exact rank, the underlying scale is not in dispute — tens of millions of Americans, delivered through a ~140,000-provider network spanning all 50 states, made DentaQuest’s 2026 data breach so consequential precisely because of how many people’s Medicaid enrollment and health data the company holds.

DentaQuest’s employee headcount is one of the most inconsistently reported metrics across business data providers, ranging from as low as 1,000 to as high as 2,500 depending on the source. The most methodologically detailed figure comes from Revelio Labs’ workforce intelligence platform, which tracked DentaQuest Group’s global headcount at 1,713 employees as of December 2025, down 4.6% from 1,795 in 2023 — a gradual, multi-year contraction rather than a single dramatic cut. Revelio’s data shows the decline wasn’t linear: headcount fell from 1,813 (2023) to 1,741 (2024), a 4.1% drop, before falling further to 1,713 in 2025, a smaller 1.6% decline, suggesting the pace of workforce reduction was slowing even before 2026 began.
Despite the overall downward trend in total headcount, DentaQuest’s hiring activity picked up substantially in 2025, with active job postings jumping 128.7% year-over-year to 83 — a signal that the company was actively recruiting in specific roles even while its total employee count continued to edge lower, a pattern often seen when organizations are simultaneously restructuring in some areas while expanding in others, such as DentaQuest’s continued build-out of new oral health centers. Revelio’s data also flagged that overall employee sentiment at the company was “negative and declining” as of mid-2026, a metric worth noting given the operational strain a major cybersecurity incident typically places on IT, legal, communications, and customer service staff in the months following disclosure.

The DentaQuest data breach unfolded over an unusually long disclosure timeline, even by the standards of major healthcare cyberattacks. The actual unauthorized network intrusion lasted just three days, from May 17 to May 20, 2026, when DentaQuest says it discovered the activity and took what it described as “immediate action to secure the network,” reporting the incident to law enforcement and engaging outside cybersecurity experts. Despite that swift initial response, the gap between discovery and full public disclosure stretched for weeks: the extortion group ShinyHunters claimed responsibility in late May, threatening to publish 234 gigabytes of stolen data after what security researchers describe as failed ransom negotiations, and DentaQuest didn’t publicly confirm the incident until early June, initially describing it only as “unauthorized access to a limited portion of our network” — a characterization that would later prove to significantly understate the eventual scope.
The gap between the May 20 discovery and the July 17 start of formal notification letters — nearly two full months — reflects the scale and complexity of the forensic investigation DentaQuest undertook with the help of Kroll, the investigation firm brought in to determine exactly whose data was affected across a member base of tens of millions. That drawn-out timeline is a recurring pattern in large-scale healthcare breaches, where the technical work of identifying every affected individual across sprawling enrollment and claims databases can take substantially longer than the initial containment of the attack itself. For broader context on how DentaQuest’s incident compares with the overall US cybersecurity landscape, the complete US data breach statistics report shows healthcare consistently ranked among the highest-risk sectors nationally, driven by the high black-market value of protected health information and the prevalence of legacy IT systems across the industry.
DentaQuest Data Breach: What Information Was Exposed
| Exposed Data Category | Detail |
|---|---|
| Names, addresses, phone numbers | Confirmed exposed |
| Social Security numbers | Confirmed — over 1.7 million found in leaked files |
| Member IDs, Medicaid numbers, Medicare numbers | Confirmed exposed |
| Dental/vision health information | Provider names, diagnoses, treatment, billing details |
| Unique email addresses (HaveIBeenPwned analysis) | 2.6 million |
| Files in leaked archive dating back to | At least 2009 |
| Credit monitoring offered to affected individuals | 24 months, complimentary |
Source: HaveIBeenPwned DentaQuest Breach Notice, June 2026; SecurityAffairs; TechRepublic
The range of data exposed in the DentaQuest breach is unusually sensitive even by healthcare industry standards, because it combines core identity theft risk factors — names, addresses, and Social Security numbers — with Medicaid and Medicare program identifiers and detailed dental and vision treatment records, including provider names, diagnoses, and billing information. Security researchers who analyzed the leaked archive found more than 1.7 million Social Security numbers, with a particularly troubling detail: many of those numbers are believed to belong to children in Texas, a population especially vulnerable to long-term identity theft risk since stolen child SSNs often go undetected for years, as minors rarely check their own credit reports.
The discrepancy between the different reported breach sizes reflects genuinely different measurements rather than simple reporting error: HaveIBeenPwned’s analysis found 2.6 million unique email addresses specifically within the leaked dataset that researchers could directly verify, while DentaQuest’s official breach notification filed with federal regulators cited more than 15 million affected individuals — a broader count based on the company’s own internal determination of whose records were potentially accessed, not just the subset whose data has been publicly confirmed in the leak. Some security outlets have cited even higher estimates approaching 23.4 million, illustrating how difficult it can be to pin down a single authoritative number in the weeks and months following a breach of this scale. DentaQuest has offered affected individuals 24 months of complimentary credit monitoring and identity theft protection, with notification letters continuing to go out on a rolling basis since mid-July.
DentaQuest Oral Health Centers and Provider Network Statistics in 2026
| Care Delivery Metric | Figure |
|---|---|
| Oral health centers operated directly | 70-75+ centers |
| States with direct-care centers | 6 |
| Focus population for direct-care centers | Rural and underserved communities |
| Total provider network (benefits administration) | ~140,000 providers |
| Recent leadership appointment | Dr. Ronke Ogunbameru, Dental Director for Texas (announced January 29, 2026) |

Beyond its core benefits administration business, DentaQuest has been steadily building out direct patient care capacity through a network of 70 to 75-plus oral health centers spread across six states, a strategy explicitly aimed at reaching rural and underserved populations who might otherwise struggle to find dentists willing to accept Medicaid patients — a chronic access problem in US dental care, since Medicaid reimbursement rates for dental services tend to run well below what private insurance pays. This direct-care expansion represents a meaningful strategic shift for a company that built its original business purely on administering benefits rather than delivering care, and it mirrors a broader industry trend of insurers and benefits administrators vertically integrating into care delivery to better control costs and outcomes.
Recent personnel moves reflect this continued regional expansion: in January 2026, DentaQuest announced the appointment of Dr. Ronke Ogunbameru as dental director for Texas, specifically providing clinical leadership in a state where the company’s oral health center network and Medicaid dental administration business both operate at significant scale — a state that, notably, also appears prominently in the 2026 breach disclosures given the large number of affected children’s records traced there. The tension between DentaQuest’s stated mission of expanding oral health access for underserved populations and the reality of exposing millions of those same vulnerable patients’ data this year captures the broader challenge facing healthcare organizations that combine deep social mission with the operational complexity of handling Medicaid-scale personal health information. For context on how significant unmet dental need remains across the broader US population that companies like DentaQuest are trying to serve, the full US dental health statistics report shows nearly 40% of high-poverty adults living with untreated tooth decay — exactly the population DentaQuest’s Medicaid-focused business model and oral health center expansion are designed to reach.
DentaQuest Ownership and Corporate Structure Statistics in 2026

| Ultimate parent company | Sun Life Financial |
| US division | Sun Life U.S. |
| Acquisition date | June 1, 2022 |
| DentaQuest’s own competitors named by trackers | Aetna, Navitus Health Solutions, Molina Healthcare, FCL Dental, United Healthcare Services |

Source: PitchBook DentaQuest Company Profile, 2026
DentaQuest’s position as a subsidiary of Sun Life Financial, acquired on June 1, 2022, places it within a large, diversified, publicly traded Canadian insurance group rather than operating as a standalone company — a structure that matters considerably for how DentaQuest is likely managing this year’s data breach fallout, since Sun Life’s substantially larger balance sheet and existing enterprise risk management infrastructure provide resources a standalone dental benefits company of DentaQuest’s size likely wouldn’t have on its own. PitchBook’s competitor analysis places DentaQuest alongside major managed care names including Aetna, Molina Healthcare, and United Healthcare Services, though DentaQuest’s specific focus on Medicaid and CHIP dental benefits differentiates it from these broader, multi-line health insurers.
That corporate backing sits within a healthcare workforce and access landscape under its own significant strain in 2026 — a dynamic directly relevant to DentaQuest’s core mission of expanding dental access for underserved Medicaid populations. The complete US doctor and surgeon shortage statistics document how over 8,400 primary care shortage areas now cover more than 92 million Americans nationwide, with dental health professional shortage areas alone affecting an estimated 58 million people — underscoring that even a well-capitalized, Sun Life-backed benefits administrator like DentaQuest operates within a broader US healthcare access crisis that no single company’s provider network, however large, can fully resolve on its own.
