Dental Practice Valuations Explained: How Much Is Your Practice Really Worth?

Mid-America’s most trusted dental practice valuation and sales

One of the first questions dentists ask when considering retirement or a practice sale is, “How much is my practice worth?” While it might seem like there should be a quick formula to get an answer, the reality is that every dental practice is unique. A proper valuation takes into account far more than just last year’s collections.

At Otten-Rey Dental Sales, LLC, we’ve conducted hundreds of dental practice valuations and appraisals across Missouri and Illinois. Our Certified Valuation Analyst expertise ensures dentists receive accurate, fair market values they can trust – whether they’re selling, buying, or planning for the future. Here’s what you need to know about how dental practice valuations really work.

The Limitations of “Rule of Thumb” Valuations

It’s common to hear a general rule of thumb such as “your practice is worth 70% of last year’s collections.” While these formulas are widely repeated, they can be dangerously misleading.

Why they fall short:

  • They ignore overhead and profitability. Two practices with the same collections but vastly different expenses are not worth the same.
  • They overlook location and demand. A practice in suburban St. Louis or Metro East Illinois may sell faster and for more money than one in a rural area.
  • They don’t reflect qualitative strengths. Patient loyalty, staff stability, and updated technology all add value – none of which show up in a basic formula.

If you rely on a shortcut, you risk undervaluing your life’s work or scaring away potential buyers with an unrealistic asking price.

Key Factors That Determine Value

A professional valuation digs much deeper than collections alone. Here are some of the most important elements that shape a practice’s worth:

Location & Market Demand

Practices in high-demand urban and suburban areas often command higher values and sell more quickly than rural practices. Proximity to hospitals, schools, or population growth centers also influences demand.

Financial Performance

Consistent revenue growth and strong profit margins give buyers and lenders confidence. Declining collections, on the other hand, may lower perceived value.

Patient Base

The size, loyalty, and demographics of your active patient base play a major role. Strong recall systems and steady new patient flow are big selling points.

Staff and Systems

A stable, experienced staff reduces risk for the buyer. Well-established systems for scheduling, billing, and patient communication also increase value.

Facilities and Technology

Modern equipment, digital records, and an updated office environment make your practice more attractive. Outdated technology or deferred maintenance may lower value.

Why Certified Valuations Are Critical

An accurate valuation is not just a number – it’s the foundation for a successful transition. As Certified Valuation Analysts, we bring professional, recognized expertise to the process. Our approach includes:

  • In-person evaluation. We visit the practice to understand the space, systems, and overall condition.
  • Detailed financial analysis. We review tax returns, profit and loss statements, and patient data.
  • Customized reporting. Every practice is unique, and our reports reflect the specific strengths and weaknesses of each office.
  • Fairness for both sides. Whether we’re working with buyers, sellers, or associates, our goal is always an accurate fair market value.

This process gives everyone involved confidence that the valuation reflects reality – not a guess.

Valuations for Buyers vs. Sellers

Both buyers and sellers benefit from certified valuations, but for different reasons:

  • For sellers: An accurate valuation ensures you don’t leave money on the table or price yourself out of the market. It also helps with retirement planning and tax strategy.
  • For buyers: A valuation gives assurance that you’re paying a fair price and helps secure financing with lenders.

When both sides have confidence in the valuation, negotiations move forward more smoothly.

When Should You Get a Valuation?

You don’t have to wait until you’re ready to sell to find out what your practice is worth. In fact, there are several situations where a valuation is beneficial:

  • 3–5 years before retirement. This gives you time to address weaknesses and improve marketability.
  • Considering an associate buy-in. A valuation establishes a fair price for both sides.
  • Mergers or acquisitions. Accurate valuations are critical for combining practices.
  • Financing. Lenders often require certified valuations for loan approvals.

Missouri and Illinois Market Considerations

The Midwest market has unique dynamics compared to coastal regions. In Missouri and Illinois, dental practices often sell for 45–70% of the previous year’s collections, depending on the factors above.

Desirable areas like St. Louis County, St. Charles County, and Metro East Illinois tend to see faster sales. Rural practices may take longer to sell but can still attract buyers when priced correctly and marketed well.

Final Thoughts

Your dental practice is likely one of your most valuable assets – and selling it may be the single largest financial decision of your career. Don’t rely on shortcuts or outdated rules of thumb.

A certified, individualized valuation ensures your practice is accurately priced, attractive to buyers, and set up for a successful transition.

At Otten-Rey Dental Sales, LLC, we’ve helped dentists across Missouri and Illinois determine their true market value and navigate smooth sales. If you’re thinking about selling – or just want to plan for the future – a professional valuation is the best place to start.

Dentist Testimonials

Kim with Otten-Rey Dental Sales truly made what I thought would be a stressful process extremely easy and painless. From our first meeting all the way until closing, Kim was always reliably there for me through out the process. I trusted her system and it was simple and seamless. I would definitely choose Kim again for my transition if l had to do it all over again.

Glenn R. Edwards DMD

When I decided to buy a dental practice, I quickly learned that practice brokers represent the seller. As a buyer, that posed some challenges. Of all the brokers I worked with in St. Louis, Kim was the only one who managed to make me feel that she was actively trying to find a practice for me to buy. Not only did she help me find a practice I loved, but she still represented her seller well and was fair throughout the entire process. Because of her, I am now the owner of a great dental practice that I love and I truly believe she made that happen for me. Thanks Kim.

Thank you both, Kim & Bill. This has been a great adventure. All is going great with the merger of Dr. Berger’s practice. Overall, I would say it is a great success. And I couldn’t have done it without both of you.

I felt my practice purchase went smoothly and efficiently with the help of Otten-Rey Dental Sales. As a buyer, I felt comfortable with the fair appraisal that Otten-Rey put on the practice and both Kim and Bill were very accommodating getting any requested info to help me do my due diligence…Otten-Rey is known in the St. Louis Dental community for being easy to work with and I strongly recommend either buyers or sellers use them in the process of your dental transition. Having their expertise, experience and organization really made things a lot less stressful.

Kim’s understanding of all aspects of a transition was invaluable. She has comprehensive knowledge of both the financial and clinical aspects of a dental office. She also provided the guidance and understanding of the legal aspects necessary to close the transaction. Thanks Kim!

Dan Twillman DMD

Kim Rey was my broker in representing me when I sold my pediatric dentistry practice. From my standpoint, Kim brought a great amount of stability to the whole process. I appreciate her insight and her levelheaded guidance on what my expectations should be, what the normal accepted practice and standards are when dealing with a buyer. The process was longer than I anticipated, but Kim kept me focused and on the right track until the transaction was completed. Throughout the process, she always made me feel like I could rely on her and that in turn gave me a great deal of comfort. I would highly recommend Kim Rey to anyone looking to buy or sell a dental practice.

Several of my friends used Kim and Bill to sell their practices and had highly recommended them. I was pleased with the thorough process of valuation and the explanation of the report. They provided frequent updates and the guide for printing the necessary reports for the valuation. They found a buyer that fit our needs. I would recommend them to the other dental offices needing the same services.
