Buy or Build? The Real Economics of Dental Practice Ownership in New York & New Jersey

By Spiro Leunes, CPA | CEO, MRL Advisory Group New Jersey & New York Dental CPAs

For many dentists, practice ownership is the single largest financial decision of their career. Eventually, every dentist who wants ownership reaches the same crossroads: do you buy an existing practice or build one from scratch?

In New York and New Jersey, that decision carries significantly more financial risk than it does in lower-cost parts of the country. Aggressive competition, high occupancy costs, staffing pressures, PPO reimbursement compression, and increasing DSO activity leave very little margin for error.

The right answer depends on the individual dentist. Cash flow timing, market conditions, risk tolerance, location, and long-term goals all play a role in determining whether an acquisition or de novo makes more financial sense.

The Appeal of De Novo Dental Practices

De novos have obvious appeal. New technology, modern branding, no legacy staffing issues, no inherited reputation problems, and complete control over the patient experience all sound attractive. On paper, building exactly what you want seems ideal.

In the New York and New Jersey market, however, building from scratch is extraordinarily expensive and the ramp-up period is often underestimated.

A modern four to six operatory practice in Northern New Jersey, Westchester, Long Island, or the outer boroughs can easily require $750,000 to more than $1 million in startup capital once construction, equipment, technology, working capital, legal fees, and marketing are included. And that is before the practice has established meaningful patient momentum.

The buildout cost is only part of the challenge. The larger issue is the amount of time required to create consistent patient flow in highly competitive Northeast markets.

Dentists routinely underestimate patient acquisition costs, staffing expenses, marketing requirements, and the time required to build a productive hygiene base. Many de novos require eighteen to thirty-six months before they truly stabilize financially. During that period, personal income expectations often collide with substantial monthly loan payments and operating costs.

Why Dental Practice Acquisitions Often Produce Faster Financial Results

In many New York and New Jersey markets, acquisitions offer a more predictable financial path.

When acquiring an existing practice, you are purchasing cash flow, patient relationships, an established hygiene program, trained staff, and an existing patient base. A properly structured acquisition can allow a dentist to step into meaningful income relatively quickly, even after debt service.

That does not mean acquisitions are easy. Quality practices in desirable suburban New Jersey and New York markets remain highly competitive. Sellers understand that DSOs are active buyers, and many practices are priced aggressively.

At the same time, price alone does not determine whether a deal is good. I have seen practices sell at premium valuations that still performed extremely well financially because the fundamentals were strong , stable patient counts, productive hygiene, favorable PPO reimbursement, strong collections, modern systems, and clear opportunities for growth.

Some of the most successful acquisitions occur when the buyer introduces procedures the previous owner referred out for years. Even modest growth in services such as clear aligners, implants, or periodontal treatment can materially increase production and profitability. Two additional clear aligner cases per month alone can add six figures of annual production.

The Biggest Mistake Buyers Make

Many buyers focus too heavily on what they are paying rather than what they are actually buying. Operational quality matters more than headline purchase price.

Two practices collecting $1.4 million annually can have dramatically different economics depending on payer mix, staffing structure, lease terms, doctor and hygiene production, collections, and patient attrition risk.

In the New York and New Jersey market, relatively small differences in PPO reimbursement rates, payroll costs, hygiene productivity, and occupancy expenses can materially impact profitability.

When a De Novo Dental Practice Makes Sense

Despite the risks, de novos can become highly successful long-term businesses.

De novos tend to work best when acquisition inventory is limited, the dentist has strong liquidity, the demographics are compelling, and there is a clearly defined growth strategy.

The most successful de novos are typically built around differentiated services and positioning. Fee-for-service models, implants, clear aligners, periodontal treatment, and other procedures less dependent on PPO reimbursement pressure can create substantial long-term value.

In the right suburban growth market, a well-executed de novo can absolutely outperform an acquisition. But execution matters enormously.

Ownership Decisions Should Be Modeled, Not Guessed

Ownership decisions should not be made emotionally.

Becoming emotionally attached to a town, office space, seller, or vision and then attempting to justify the economics afterward is the wrong approach.

Before signing an LOI, negotiating a lease, or taking on construction debt, the numbers should be modeled realistically using actual New York and New Jersey market assumptions. That analysis should include PPO reimbursement realities, staffing costs, occupancy expenses, debt service, procedure mix, collection trends, and projected owner compensation.

The difference between a great opportunity and a stressful one is often visible in the numbers long before closing.

Final Thoughts

For many dentists in the New York and New Jersey market, a well-run acquisition still represents the faster and lower-risk path to strong income and long-term wealth creation.

That said, a carefully planned de novo in the right market, combined with strong execution, can also create tremendous long-term value.

The key is understanding what you are truly buying or building before committing.

Before signing a letter of intent or committing to a buildout, perform proper due diligence and run the numbers carefully.
