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

Our research found no general non-compete statute in South Carolina — the state polices non-competes through its courts, and the rule comes from the South Carolina Supreme Court's decision in Poole v. Incentives Unlimited, 345 S.C. 378 (2001): a covenant not to compete is enforceable if it is not detrimental to the public interest, is reasonably limited as to time and territory, and is supported by valuable consideration.

As far as our research found, the test applies with equal force to the associate dentist, the hygienist and the assistant at your front desk — what changes by role is how you draft, not which law applies.

And there is a trap built in: South Carolina courts will not repair an overbroad covenant, so the agreement has to be right when it is signed.

There is no federal rule to fall back on either: the Federal Trade Commission's Non-Compete Clause Rule was set aside in court and never took effect, and in a final rule published February 12, 2026, the Commission removed it from the Code of Federal Regulations — so as of October 2026 there is no federal rule banning employee non-competes, including for dental practices.

Poole v. Incentives Unlimited, 345 S.C. 378 (2001), is the anchor.

There the Supreme Court quoted the test from S.C. Fin. Corp. of Anderson v. West Side Fin. Co. (1960): a covenant not to compete is enforceable if it is not detrimental to the public interest, is reasonably limited as to time and territory, and is supported by valuable consideration.

When the covenant gets signed matters as much as what it says.

Under Poole, a covenant entered into after employment has begun needs separate consideration beyond continued at-will employment to be enforceable — such as a raise or a promotion.

For a dental practice that is a scheduling instruction: hand the covenant over with the offer letter, or attach it to a genuine raise or promotion.

Two later decisions define what happens when the drafting misses, and the headline is simple: the restrictions stand or fall on their own terms, and a court will not insert a geographic limit the parties left out.

Start with the caveat: our research for this page found no South Carolina statute specific to non-competes for dentists, dental hygienists or other health care workers as of October 7, 2026, so the general case-law test is the law your covenants live under.

Treat that as a research finding rather than settled law — the S.C. Code was not searched exhaustively for a health care provision, and South Carolina's dental-specific case law was not researched for this page.

A South Carolina employment attorney can confirm both before you rely on the point.

The statutory route does exist elsewhere: Texas has a statute that specifically addresses non-competes relating to the practice of dentistry.

South Carolina has no equivalent as far as our research found, which is why the case-law reasonableness test — and the drafting discipline below — does all the work here.

It also means every role in the practice — associate dentist, hygienist, assistant, front desk — stands on the same footing: as far as our research found, no statute hands any of them an exemption, and none gives you a formula either.

Poole gives you the checklist: no detriment to the public, limits on time and territory that are reasonable, and valuable consideration underneath.

Because the rule is case law rather than a statute, our research located no maximum term or mileage radius written down to aim at — reasonableness is judged from the covenant itself.

Three decisions turn that checklist into drafting rules:

• Nothing gets rewritten. In Poynter Investments v. Century Builders, 387 S.C. 583 (2010), the Supreme Court held that the restrictions in a non-compete cannot be rewritten by a court or limited by the parties' agreement — they must stand or fall on their own terms. An overbroad covenant is not trimmed to fit; it fails.
• No territory, no covenant. The same line of cases — Stonhard v. Carolina Flooring Specialists (2005) — held that a court will not insert a geographic limit into a covenant that lacks one, because that would add a term the parties never negotiated. Name the territory yourself, in the contract.
• No "any capacity" bans. Poynter describes Faces Boutique v. Gibbs (1995), where a covenant barring an esthetician from being associated in any capacity with a competing business was held overbroad. Aim the same wording at a hygienist or assistant and you have reproduced the red flag: tie the restriction to the clinical or patient-facing work the person actually did.

No source we reviewed gives you a number — no approved term in months, no safe radius in miles.

Set the shortest term and the tightest territory that actually protect the practice's patient base, and have a South Carolina employment attorney judge the result before you hand it over.

A non-solicit restrains different conduct than a non-compete: it stops a departing team member from targeting your patients or your staff, not from working.

Our research for this page covered South Carolina's non-compete case law; how a particular patient or staff non-solicit fares in a South Carolina court is a separate question those sources do not settle, so put the clause in front of employment counsel.

The mechanics, and how states around the country treat these clauses, are in our guide to patient and staff non-solicits.

Confidentiality gives you a second tool, and this one is federal.

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 — and business information, a patient list included, qualifies as 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 then, a DTSA injunction cannot bar someone from taking a new job: conditions on the new employment must rest on evidence of threatened misappropriation, not merely on what the person knows.

That last condition is the operational one: the reasonable-measures requirement looks at the measures you have actually taken to keep the information secret.

Limited logins, no unlogged exports, and confidentiality terms in the agreement itself are the kinds of measures that leave trade-secret law something to protect — put them in place before a departure, not after.

South Carolina's no-rewrite rule makes covenant drafting a one-shot exercise, so spend the effort where it counts:

• Draft narrow the first time. A defined term, a named territory, and restricted activities tied to the clinical work the person actually performs — written to be reasonable as signed, because there is no edit pass.
• Time the signature to the consideration. The covenant goes in the offer packet at hire, or rides on a genuine raise or promotion; continued employment alone does not carry one signed mid-stream.
• Protect the relationships, not just the map. Patient and staff non-solicits and a genuinely guarded patient list reach the two assets that actually walk out the door.
• Recover training spend separately. Where you fund a course or credential for a hygienist or assistant, our guide to training repayment agreements covers how they work and where states restrict them.
• Write the operational terms into the agreement. Notice periods, patient-record handling on departure, schedule handover — continuity should not depend on the covenant holding up.

Before signature, confirm the clinician's credential — our guide to dentist licensure in South Carolina covers what an associate needs — and have a South Carolina employment attorney review the covenant against the current case law.
