East vs. West: Who Has a Bigger Sweet Tooth—And What it Means for DSO Revenue

When people think of East Coast vs. West Coast rivalries, they typically envision differences in sports, slang, or lifestyle. But what about dentistry? 

At Zuub, we analyzed 24.7 million insurance verifications across more than 350 payers to uncover surprising regional trends in dental care. What we found isn’t just trivia — it has direct implications for Dental Support Organizations (DSOs) and their ability to optimize patient engagement, operations, and revenue cycle management.

East Coasters Visit the Dentist 25% More Often for Cavities

Our data show that East Coast patients make 25% more cavity-related visits than West Coast counterparts — with fillings and composite restorations being the most common procedures.

Beyond Zuub’s proprietary dataset, national surveys highlight a similar story: according to the American Dental Association (ADA) Health Policy Institute, only about 43% of U.S. adults visited a dentist in 2021. That means utilization is far from universal nationwide.

However, in many Eastern states, coverage and utilization rates exceed the national average. For example, the CDC’s National Center for Health Statistics (NCHS) reports that in New England and the Middle Atlantic, adults are significantly more likely to have private dental coverage and among the least likely to skip a dental visit in a given year (CDC, NCHS Data Brief No. 336).

Why this matters:

• Fewer surprises: When patients come in earlier and more often, practices face fewer high-risk, last-minute cases.
• Stable operations: Consistent throughput helps stabilize staff utilization, reduces idle time, and smooths revenue.
• Lower costs over time: Preventive cultures catch issues early, reducing escalation and default risk down the line.

For a DSO with 100 practices, a 25% increase in cavity-related visits could represent tens of thousands of additional encounters annually — translating into steadier chair utilization and millions in more predictable revenue.

West Coasters Are Paying 16% More Per Visit

Meanwhile, when West Coast patients do seek cavity care, it costs 16% more per visit on average than their Eastern peers. This aligns with broader evidence of cost disparities: according to the CDC’s National Center for Health Statistics (NCHS), out-of-pocket dental procedure costs can vary by more than 100% between the lowest- and highest-cost states (CDC, NCHS).

To put this in perspective, CareCredit estimates the national average cost for a routine exam and cleaning at about $203, though prices vary widely depending on geography (CareCredit).

But more crucial are the hidden costs:

• Longer gaps between visits often mean more invasive, higher-priced procedures.
• Overhead in dense coastal metros (e.g., San Francisco, LA, Seattle) pushes fees upward.
• Lower benefit utilization or gaps in coverage awareness mean patients (or DSOs) shoulder more of the cost.

What this signals for DSOs:

• Greater AR risk: High-cost visits bring more patient sticker shock, higher bad-debt exposure, and unpredictable revenue.
• Stronger case management needed: Practices in the West must proactively manage case acceptance and financial counseling to protect margins.
• Revenue volatility: Compared to steadier East Coast throughput, West Coast “spikes” are harder to forecast without reliable, real-time intelligence.

For that same 100-practice DSO, a 16% higher average treatment cost could expose the organization to millions in additional AR risk each year — especially if patient out-of-pocket responsibility rises and case acceptance drops.
