10 Key Facts About Restrictive Covenants for Dentists (Non-Compete Agreements)

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

If you’re considering signing with a dental practice in the St. Louis area, chances are you’ll be asked to sign a Restrictive Covenant (also called a non-compete agreement).

Over the years, we’ve worked with many dentists facing these agreements—either at the start of employment or when preparing to leave and open their own practice. Here are 10 key facts every dentist should know:

1. Will I have to sign one?

Almost always. Most private practices include a Restrictive Covenant in their Employment Contract. All DSOs require one.

2. Why do they exist?

Employers want to prevent an associate from leaving and opening nearby, drawing patients away.

3. What’s considered “normal”?

In Greater St. Louis: typically, 10 miles and 5 years.
In outstate or rural areas: 15–20 miles may be common.

4. Are they enforceable?

Yes—if the terms are considered reasonable.

5. What does “reasonable” mean?

It varies by state and location. The goal is to restrict you from practicing where your employer draws patients.

6. How are they enforced?

If you violate the agreement, your former employer can seek an injunction preventing you from practicing.

7. Can they be negotiated?

Sometimes. Even some DSOs will negotiate terms, depending on circumstances.

8. What if my employer has multiple offices?

You should only be restricted at the location where you primarily practice.

9. What happens if the practice is sold?

  • Illinois: Employment contracts are generally assignable, so your Restrictive Covenant likely applies to the new owner.

  • Missouri: Less clear – outcomes can vary.

10. What else should I know?

Every situation is different. For legal interpretation, consult your attorney. For practical insight, give us a call—we’re happy to share what we’ve seen work in real-world cases.

Bottom line: Restrictive Covenants are a major factor when deciding whether to purchase your own practice or sign on as an associate. Understanding your rights and limitations upfront can save you headaches later.

I have worked with Otten-Rey Sales as a “buyer” for two separate practice purchases in recent years. From the buyer’s perspective- I have found Kim very easy to communicate with and very accommodating to any requests I may have had while doing my due diligence. Kim has been a great resource and when the time comes to consider selling, I would absolutely feel comfortable asking her to represent me as a seller as well.

My transition experience was truly smooth and easy from start to finish. Kim made what could have been a stressful process feel very manageable. She was always quick to respond, proactive in communication, and genuinely cared about making sure everything went right. I felt supported and informed every step of the way, which gave me a lot of peace of mind during such a big change. It was a wonderful experience overall, and I’m very happy with how everything turned out. I would absolutely recommend Kim to any dentist going through a practice sale or transition — she really goes above and beyond.

Dr. Hetal Patel Clayton, MO Practice

We consider ourselves lucky to have known and worked with Kim Rey for so many years. She was involved in our purchase 19 years ago and has been a supportive, positive presence in our office management since that time, up until the successful sale of our practice. We feel like our timeline was truly understood when meeting with Kim about our needs and our goals for our practice and our family. She helped to guide us each step of the way with those goals in mind. We feel like the communication was clear and consistent with her management and care of our sale. We always felt like a priority to her and it truly made the sale of our practice an exciting and enjoyable process. I would highly recommend Kim Rey to anyone looking to buy or sell a dental practice.

Dr. Patrick Murphy Arnold, MO Practice

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.

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.

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!
