Are Non-Competes Enforceable for Dentists and Dental Staff in Missouri?

A non-compete signed by an associate dentist, a hygienist or a dental assistant is enforceable to the extent it is narrowly tailored geographically and temporally, and only to protect the practice's trade secrets or customer contacts.

• Case law, not a statute. The governing test comes from Healthcare Servs. of the Ozarks v. Copeland, a 2006 Missouri Supreme Court decision; the statute beside it, RSMo § 431.202, covers non-solicitation covenants and expressly does not affect covenants not to compete.
• The burden is yours. Under Copeland, the employer must substantiate an asserted trade-secret interest with specific evidence, not general assertions.
• No federal backstop either way. The FTC's 2024 non-compete rule was set aside in court, never took effect, and was removed from the Code of Federal Regulations on February 12, 2026, so non-competes for dental staff nationally live or die on state law.

Missouri non-compete law is case law.

In Healthcare Servs. of the Ozarks, Inc. v. Copeland, 198 S.W.3d 604 (Mo. banc 2006), the Missouri Supreme Court held non-competes enforceable to the extent narrowly tailored geographically and temporally, and not enforceable to protect an employer from mere competition by a former employee.

The statute that does exist points elsewhere.

RSMo § 431.202, effective July 1, 2001 (Senate Bill 288), governs written covenants not to solicit, recruit or hire employees, and subsection 431.202.3 provides that the statute is not intended to create, or to affect the validity or enforceability of, employer-employee covenants not to compete.

Your non-compete therefore stands or falls on Copeland, not on a statutory formula.

What the statute does supply is a safe harbor for non-solicits: under § 431.202.2, a covenant covered by its non-solicitation subdivisions is conclusively presumed reasonable if it lasts no more than one year after employment ends.

Nothing equivalent attaches to a non-compete.

The leading Missouri case is itself a healthcare case — Copeland arose from a home health care business — and its framework turns on tailoring and protectable interests, not the industry or the license behind the signature.

The same test covers the associate dentist, the hygienist, the chairside assistant and the front desk.

On the statutory side, this research found no Missouri statute specifically restricting non-competes for dentists, dental staff or other health care workers as of October 2026, so a dental covenant is judged on the general rule.

Legislation moves — confirm any healthcare non-compete bill with the Missouri Legislature before relying on the point.

Neither is there an income gate under the Missouri law this research verified: the Copeland test and RSMo § 431.202 key enforceability to tailoring and the interest behind the covenant, not to what the employee is paid.

The license behind the signature is its own matter — our guide to dentist licensure in Missouri covers that path.

The interest.

Copeland protects two interests: trade secrets and customer contacts.

For a practice, the covenant has to point at something specific — the relationships and information the clinician actually touched — not a general wish to thin the local hiring market.

Time and area.

The covenant must be narrowly tailored geographically and temporally, and the verified Missouri law supplies no preset term or radius for a non-compete.

The nearest reference point is Copeland itself, where the covenants at issue — 100 miles and two years — were not challenged as unreasonable in time or distance.

Not challenged is not the same as endorsed: draft to the practice's actual footprint rather than to a number.

The evidence.

Under Copeland, the burden of proof rests on the employer to substantiate its asserted interest in its trade secrets with specific evidence, not general assertions.

Name the systems, records and referral information you mean, and identify the patient relationships the clinician actually handled.

Missouri's statute does the work here.

Under RSMo § 431.202.1(3), a reasonable written covenant not to solicit, recruit or hire employees is enforceable when it protects confidential or trade-secret information, or customer relationships, goodwill or loyalty.

Subdivision (4) goes further: the covenant is enforceable even without those protectable interests so long as it lasts no more than one year after employment ends — but not for employees who provide only secretarial or clerical services.

A purely clerical front-desk hire's clause needs subdivision (3)'s protectable interest behind it.

Confidentiality terms do the complementary work.

Under the Defend Trade Secrets Act, the owner of a misappropriated trade secret related to a product or service in interstate commerce can sue in federal court — but business information, including a compiled patient list, is a trade secret only if you took reasonable measures to keep it secret and it has independent economic value from not being generally known.

Even a DTSA injunction cannot bar someone from a new job — conditions must rest on evidence of threatened misappropriation, not merely on what the person knows.

The leverage is in how you use the room Missouri gives you:

• Draft narrow on purpose. Keep the duration short and the area tight to the locations where the clinician actually treated patients — you will have to defend both as narrowly tailored under Copeland.
• Build the evidence file now. Name the trade secrets and customer contacts you mean — systems, records, referral relationships, the patients the clinician actually saw — and keep proof; general assertions are what Copeland discounts.
• Put the statutory non-solicit in writing at one year. Subdivisions (3) and (4) plus the one-year conclusive presumption give a Missouri practice its most predictable covenant; remember the clerical exception.
• Lock the patient list down. Limited logins and no personal exports are the kind of reasonable measures the DTSA requires; without them a patient list is not a trade secret, whatever it is worth.
• Where you fund training, a training repayment agreement is a separate tool — our guide to training repayment agreements covers how they work.
