3 Big Mistakes New Buyers Make When Evaluating a Dental Practice

by PracticeCFO | November 21, 2025
A modern dental office features a blue dental chair, overhead light, and tools against a gray wall. A potted plant adds a touch of nature.

Buying a dental office should be the moment your career shifts into a higher level of income and control. But that only happens when you choose the right practice. A strong office can give you predictable production, a steady patient base, and a better work-life. The wrong office can keep you stuck at associate-level income while carrying a large loan.

Most buyer setbacks come from misreading the practice they are trying to purchase. These three mistakes are common, costly, and completely avoidable when you know what to look for.

1. Judging a Practice Only by Last Year’s Collections

Many new buyers focus on one number: the seller’s recent revenue. This is one of the worst ways to judge a practice. The seller’s production reflects the seller’s skills, speed, treatment style, and clinical habits. None of these may match yours.

Several issues hide behind high collection numbers:

• The seller may have completed most of the profitable work already

Some sellers produce a heavy volume of crowns, implants, or larger cases. If every patient has fresh restorative care, there is nothing left for you to diagnose. You step in and suddenly numbers drop because your hands have nothing to do.

• You cannot assume you can repeat the seller’s treatment pattern

If a seller is extremely aggressive or extremely fast with crown placement, you may not match their pace. Your income then falls short of the financial reports you reviewed.

• Collections tell you the past, not your future

You should be asking:
What will the practice produce once I own it?

That answer rarely matches last year’s statement.

• Production mix can create fake confidence

A year with many crowns looks strong, but those cases do not repeat yearly. A year with under-diagnosed hygiene patients looks weak, yet may carry more long-term potential for you.

A financial statement is a starting point. It is not a guarantee of your income.

2. Ignoring Patient Base Quality Instead of Patient Count

Most buyers look at patient count. Few look at patient value. This is a major mistake.

A practice might have 1,000 active patients and still be a weak buy. Another practice might have 1,200 or 1,800 patients and be a far better long-term fit. The transcript gives a clear example that shows why:

Scenario A: 1,000 patients and 1,000 crowns in a year

This often means the seller has already completed nearly every major restorative procedure. The patient base is fully restored. You walk into an office where patients need cleanings, occasional fillings, and not much more.

Your production potential drops right away.

Scenario B: 2,000 patients and only 200 crowns in a year

This is a high opportunity practice. Many older sellers reduce their treatment planning over time. They do not provide full care. They only treat the tooth that hurts.

When you review charts, you often find:

  • Untreated decay
  • Fractured teeth
  • Crowns that should have been recommended
  • Restorations that have been ignored for years

This gives the buyer a natural path to growth without advertising or long marketing campaigns.

Why this matters:

A practice with weak seller production can outperform a “high production” practice once you step in with proper diagnosis.

Opportunity matters more than last year’s collections.

3. Forgetting That Post Close Numbers Change

The seller’s financials do not match your financials. This is one of the biggest misunderstandings buyers face.

Once you close, several major expenses shift right away.

• Rent may increase

If the seller owns the building, they may be paying themselves below market rent. You will not have that arrangement.
Your rent may double or rise significantly.

• Payroll may look very different

If the seller’s spouse was the office manager, you now need a paid employee. If a family member was underpaid, you need a replacement at the market rate.
Your payroll can climb immediately.

• You now have a loan payment

The seller often has no practice loan during the final years. You do. That payment reduces your take-home income each month.

• Insurance reimbursement may drop

You may not qualify for the same plans the seller accepted.
Delta Premier is a common example. Some sellers are paid far more per crown than new owners will be.
Your fees may be lower for the same work.

• Taxes change once you own the practice

Your tax structure shifts from associate pay to owner income with overhead, payroll, and debt to consider.

This is why the smart buyer does not ask, “How much did the seller take home?”
The real question is, “What will I take home after overhead, debt, and taxes under my name?”

Final Thoughts

Buying the right dental practice can double your income and give you more control over your schedule. Buying the wrong one can leave you stuck, frustrated, and unable to grow.

You avoid these outcomes by:

  • Looking past last year’s revenue
  • Studying the true condition and opportunity within the patient base
  • Adjusting the financials for what they will look like after closing

When you evaluate a practice with these points in mind, you give yourself a much safer and stronger path into ownership.
