Are Non-Competes Enforceable for Dentists and Dental Staff in Illinois?
Illinois' Freedom to Work Act sets earnings floors and paperwork rules for dental covenants signed after January 1, 2022 — here is what holds up against an associate, hygienist or assistant.
Yes — an Illinois dental practice can enforce a non-compete against an associate dentist, hygienist or assistant, but the Illinois Freedom to Work Act (820 ILCS 90) decides who can be asked to sign one at all, and it sets consideration, notice and reasonableness conditions for covenants signed after January 1, 2022.
An employee who defeats an enforcement suit recovers attorney's fees, so how you draft matters as much as whether you use one.
Rules vary by state and change
This guide explains federal rules and the state rules it names, as of the date above.
Employment law and dental-practice rules differ by state and are revised often, so confirm current requirements with your state dental board, labor agency or employment counsel before you act on them.
It is general information, not legal advice.
The short answer for Illinois
Yes, but only above an earnings line.
Under section 10(a) of the Illinois Freedom to Work Act (820 ILCS 90), no employer may enter into a non-compete with an employee whose actual or expected annualized earnings are $75,000 or less, and that floor rises to $80,000 on January 1, 2027.
The Act measures the employee's actual or expected annualized rate of earnings, and it applies to any employee.
An associate dentist, a hygienist, an assistant and a front-desk hire all stand under the same line: the earnings number decides, not the job title.
Above the line, the covenant still has to clear the rest of the Act: adequate consideration, written advice to consult an attorney with at least 14 calendar days to review, and five validity conditions — with attorney's fees waiting if the employee defeats an enforcement suit.
The governing statute or case law
Illinois law here is statutory.
The Illinois Freedom to Work Act, 820 ILCS 90, holds the thresholds, the paperwork and the reasonableness test in one place.
Its thresholds and notice rules apply to covenants entered into after January 1, 2022 (Public Act 102-358); a covenant signed before that date is not governed by those rules — have counsel review any pre-2022 agreement before you rely on it.
| Provision | What it requires or bars |
|---|---|
| 820 ILCS 90/10(a) | No non-compete unless earnings exceed $75,000 ($80,000 from January 1, 2027). |
| 820 ILCS 90/10(b) | No customer or employee non-solicit unless earnings exceed $45,000 ($47,500 from January 1, 2027). |
| 820 ILCS 90/5 | Defines adequate consideration; excludes sale-of-business covenants. |
| 820 ILCS 90/20 | Void without written advice to consult an attorney and 14 calendar days to review. |
| 820 ILCS 90/15 | Illegal and void unless the five validity conditions are met. |
| 820 ILCS 90/25 | Employee who defeats an enforcement suit recovers all costs and reasonable attorney's fees. |
| 820 ILCS 90/35 | Court may reform or sever; extensive rewriting may be against public policy. |
No federal rule banning employee non-competes overrides any of this.
The Federal Trade Commission's 2024 attempt at one was set aside in court before it took effect, and the agency removed the rule from the Code of Federal Regulations on February 12, 2026, so state law governs what your Illinois agreements can do.
How the states compare is covered in our guide to non-competes for dental staff nationally.
Dentist- and healthcare-specific rules
Illinois has no dentist-specific non-compete rule.
The Act's only healthcare-specific provision, section 10(f) effective January 1, 2025, makes covenants unenforceable with respect to the provision of mental health services to veterans and first responders — dentistry is not covered by it.
So an associate dentist here is simply an employee: the earnings thresholds and the same five validity conditions decide the covenant, exactly as they do for a hygienist, an assistant or a front-office hire.
The Act holds no buyout formula or mileage cap for dental roles to borrow from.
One provision does put a dentist in a different position: selling.
Under section 5, a "covenant not to compete" does not include an agreement made by a person purchasing or selling the goodwill of a business or otherwise acquiring or disposing of an ownership interest.
A selling dentist's covenant with the buyer sits outside the Act's definition of a covenant not to compete, so the pay thresholds do not apply — it is transaction paperwork to draft with counsel.
What courts require (time, area, legitimate business interest)
Section 15 makes a covenant not to compete — or not to solicit — illegal and void unless all five of these hold:
- Adequate consideration. Defined in section 5: at least 2 years of employment after signing, or other professional or financial benefits adequate to support the covenant.
- Ancillary to a valid employment relationship.
- No greater than required to protect a legitimate business interest.
- Not unduly harsh on the employee.
- Not injurious to the public.
Time and area live inside the third condition.
The statute states its test as conditions rather than a table of numbers, so the term and area you pick are evidence in an argument — that the restraint is no greater than the interest it protects.
Name the interest, and size the covenant to it.
Two provisions price the drafting.
A court may reform or sever an overbroad covenant rather than void it, but the Act cautions that extensive judicial rewriting may be against public policy — don't draft wide and count on a trim.
And an employee who defeats your enforcement suit recovers all costs and reasonable attorney's fees, so overreach is the expensive option.
Non-solicitation and confidentiality clauses
The Act's lower threshold belongs to the clause to lean on.
Section 10(b) bars customer or employee non-solicitation covenants for employees earning $45,000 or less a year, rising to $47,500 on January 1, 2027 — and for a dental practice, those customers are your patients.
Above that line, the same consideration and notice rules and the same five conditions apply to a covenant not to solicit as to a covenant not to compete.
How these clauses are built is covered in our guide to patient and staff non-solicits.
Confidentiality runs on a separate federal track.
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 a compilation such as a patient list qualifies only if you took reasonable measures to keep it secret and it has independent economic value from not being generally known.
A DTSA injunction cannot bar a new job outright: conditions on new employment must rest on evidence of threatened misappropriation, not merely on what the person knows.
What Illinois dental practices should do instead or in addition
The Act is workable once you treat it as a checklist:
- Check the earnings line first. $75,000 or less means no non-compete; $45,000 or less also means no non-solicit — both floors rise on January 1, 2027, to $80,000 and $47,500.
- Build the paperwork into the offer. Written advice to consult an attorney, and the covenant in hand with at least 14 calendar days to review before employment starts.
- Plan the consideration. A covenant handed over at exit, with nothing new given in return, has no two years of post-signing employment behind it — it needs other professional or financial benefits adequate to support it.
- Use the narrower tools. A patient-and-staff non-solicit above the threshold, written confidentiality terms, and — if you fund training — a repayment clause, which carries its own limits; see our guide to training repayment agreements.
- Hire with covenants in view. Ask candidates from other practices whether they are bound by one, and confirm licensure separately — starting from dentist licensure in Illinois.
- Keep people instead of litigating. A non-compete only restricts where they may work if they leave; a schedule people can plan around gives them reasons to stay.
Reading your own agreement rather than drafting one?
The worker's side is covered in our guide to dentist non-competes.
Whichever side you are on, have Illinois employment counsel review the document.
Before you hand an Illinois hire a covenant
- Check actual or expected annualized earnings: $75,000 or less means no non-compete; $45,000 or less means no patient or staff non-solicit either.
- Remember both floors rise on January 1, 2027 — to $80,000 for non-competes and $47,500 for non-solicits.
- Advise the employee in writing to consult an attorney and give at least 14 calendar days to review.
- Line up adequate consideration: two years of employment after signing, or professional or financial benefits adequate to support the covenant.
- Name the legitimate business interest, and keep the term and area no greater than it requires.
- Have Illinois employment counsel review the final document before anyone signs.
Questions employers ask
Can a dental hygienist or assistant in Illinois be asked to sign a non-compete?
It depends on earnings, not the job title.
Under 820 ILCS 90/10(a), no employer may enter into a non-compete with an employee whose actual or expected annualized earnings are $75,000 or less, rising to $80,000 on January 1, 2027.
Above that line a covenant is possible, but it still needs adequate consideration, the written attorney-consult notice with 14 days to review, and all five validity conditions.
Do the Illinois thresholds apply to a covenant signed before 2022?
No. The Freedom to Work Act's thresholds and notice rules apply to covenants entered into after January 1, 2022 (Public Act 102-358).
An older agreement is not governed by those rules, and how it holds up depends on the law that applied when it was signed — have Illinois employment counsel review any pre-2022 covenant before you rely on it or try to enforce it.
What happens if my practice sues to enforce a non-compete and loses?
Under 820 ILCS 90/25, an employee who defeats an employer's suit to enforce a non-compete or non-solicit recovers from the employer all costs and all reasonable attorney's fees.
That fee-shifting is why screening matters more than the signature: check the earnings threshold, the consideration, the notice and the five validity conditions before you file.
Does Illinois have a special non-compete rule for dentists?
No. The Act's only healthcare-specific provision, 820 ILCS 90/10(f) effective January 1, 2025, concerns mental health services to veterans and first responders.
An associate dentist is treated like any other employee: the earnings thresholds, consideration, notice and validity conditions decide the covenant.
Where a dentist's position does shift is a sale of the practice — see the next question.
Can I require a selling dentist not to compete after I buy the practice?
Yes — a selling dentist's covenant is not a "covenant not to compete" under the Act.
Under 820 ILCS 90/5, a covenant not to compete does not include an agreement made by a person purchasing or selling the goodwill of a business or otherwise acquiring or disposing of an ownership interest, so the pay thresholds do not apply to a selling dentist's covenant with the buyer.
It is transaction paperwork; have counsel draft and review it.
Are patient non-solicits enforceable against Illinois dental staff?
Only above the earnings line.
Illinois bars customer or employee non-solicitation covenants for employees earning $45,000 or less a year, rising to $47,500 on January 1, 2027 — and for a dental practice, those customers are your patients.
Above the threshold, the same notice and validity rules apply.
Separately, a patient list can qualify as a trade secret under federal law only if you took reasonable measures to keep it secret.
