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

Yes, with a judge between you and the covenant.

The research for this guide found no Iowa statute that voids staff non-competes outright — and none that blesses them either.

What governs is the framework the Iowa Supreme Court applies to any employment covenant: a non-compete is enforced if it is reasonably necessary to protect the employer's business, not unreasonably restrictive of the employee's rights, and not prejudicial to the public interest.

That framework does not sort your staff by role.

An associate dentist, a hygienist and a chairside assistant all stand before the same test — nothing in the case law this research found separates them by license, title or pay.

This page is the Iowa employer's view.

If you are a dentist weighing a covenant you have been handed, that is the worker's side of the question — see our guide to dentist non-compete agreements.

The federal picture is settled for now: the Federal Trade Commission's 2024 Non-Compete Clause Rule was set aside in court and never took effect, and in a final rule published February 12, 2026 the FTC removed it from the Code of Federal Regulations — so as of October 2026 there is no federal rule banning employee non-competes at a dental practice.

How other states treat dental covenants is covered in our guide to non-competes for dental staff nationally.

In Iowa, the research behind this guide found no general statute governing employee non-competes — which leaves case law.

That is what this review found, not an exhaustive certification of the Iowa Code; have Iowa employment counsel confirm the current state of the law before you rely on it.

Three Iowa Supreme Court decisions do the work a statute would:

• Iowa Glass Depot, Inc. v. Jindrich, 338 N.W.2d 376 (Iowa 1983) — states the test your covenant has to pass.
• Ehlers v. Iowa Warehouse Co., 188 N.W.2d 368 (Iowa 1971) — establishes that, absent employer bad faith, a court may enforce an overbroad covenant in part rather than not at all.
• Dental Prosthetic Services, Inc. v. Hurst, 463 N.W.2d 36 (Iowa 1990) — a dental-business covenant case, and a drafting lesson in both directions.

No Iowa statute singling dentists out — in either direction — was found by this research: nothing restricting non-competes for dentists at private employers, nothing creating a special enforcement rule for dental practices, and no separate rule for hygienists or assistants.

Whatever protects or limits you is the general case-law framework, applied to the facts of the departure.

The test also has no earnings trigger: as the Iowa Supreme Court states it, enforceability turns on necessity, reasonableness and the public interest — not on what the employee is paid.

An income gate is another state's creation: Illinois bars non-competes against employees earning $75,000 a year or less (rising to $80,000 on January 1, 2027) — and none was found for Iowa in this research, though the hardship half of the framework still asks whether enforcement is fair to the employee.

Contrast Texas, which writes the shape of a compliant dentist covenant into its statute — among other conditions, a buyout no greater than the dentist's total annual salary and wages at termination, a one-year term and a five-mile radius measured from where the dentist primarily practiced.

Iowa offers nothing comparable as far as this research found.

Iowa Glass Depot gives the test summarized above — necessity, reasonableness, public interest — and adds this: you carry the initial burden of proving the covenant is reasonably necessary to protect your business.

What does necessary look like to an Iowa court?

The cases lean on an employee's close proximity to customers combined with knowledge gained through employment that could be used to take those customers — the hygienist who treats your recall patients visit after visit, the associate your patients ask for by name.

The closer someone sits to your patient relationships, and the more of your operation they know, the stronger your showing.

On time and area: as far as the research for this guide found, no Iowa statute sets a mileage radius or a year cap, so the question is whether your numbers are reasonable under the case law.

The covenant in Hurst barred a similar business within 50 miles for three years — those were that agreement's terms, not numbers Iowa sets — and what decided the case was the agreement's silence about former customers and the court's reading of its words.

Draft to your patient draw and the lifespan of the relationships you protect — not to a magic number.

If the clause is too broad, Ehlers is the good news: absent employer bad faith, Iowa courts enforce non-competes to the extent reasonably necessary to protect the employer without imposing undue hardship on the employee, when the public interest is not adversely affected — an overbroad covenant may come back trimmed, not dead, a deliberate break with Iowa's older refusal to modify covenants.

Do not bank on the trim: the court's version protects what a judge thinks your business needed, not what you drafted.

Hurst is the case to read before you sign off on covenant language.

A dental laboratory barred its production manager from a similar business within 50 miles for three years — but the agreement contained no language prohibiting contact with former customers or accepting work from them.

When the former employee began serving dentists in the area who contacted him, the Iowa Supreme Court held he had not violated it.

The court also construed any ambiguity in the term "business" against DPS, the party that drafted the agreement.

If your clause can be read more than one way, Hurst shows how an Iowa court can resolve that ambiguity: against the drafter.

Say exactly what you mean.

So be explicit: if patient relationships are the point, say so in a dedicated patient non-solicit — a clause restricting who the former employee may contact, not where they may work — instead of expecting a general "similar business" ban to do work it was never written to do.

For how these clauses are structured, see our guide to patient and staff non-solicits.

One caveat: Hurst involved a dental laboratory, not a patient panel, and this research found no Iowa decision squarely on a dental patient non-solicit — treat it as a drafting direction, and have counsel review the clause.

Confidentiality is the quieter protection.

Under the federal Defend Trade Secrets Act, a 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 — measures such as access controls and signed confidentiality terms are the kind of record you would point to.

The DTSA lets the owner of a misappropriated trade secret related to a product or service in interstate commerce sue in federal court, but an injunction cannot prevent a person from entering into an employment relationship: conditions on new employment must rest on evidence of threatened misappropriation, not merely on what the person knows.

None of this argues against covenants in Iowa — it argues for writing them for the test they will actually face.

• Draft narrow, and say what you mean. Tie the restricted area to your patient draw and the term to how long the protected relationships last — the trim a court may apply is its judgment of what your business needed, not yours.
• Build the necessity record. You carry the initial burden, so know your proof before you need it — which patients the person treated, and what confidential pricing or scheduling knowledge they hold.
• Add an express patient non-solicit. Hurst shows what a silent agreement does not stop.
• Price training separately. If the real concern is recovering the cost of specialized training, training repayment agreements are a different tool with their own rules — see our guide to training repayment agreements.
• Confirm licensure at hire. A covenant only matters if the person can practice — our guide to dentist licensure in Iowa covers what Iowa requires.
• Have Iowa employment counsel review the final language before it goes into an offer packet, not after a court has been asked to enforce it.
