What are the Illinois rules for dental advertising?
Illinois dental advertising is governed by Section 45 of the Illinois Dental Practice Act (225 ILCS 25/45) and the department's rule at 68 Ill. Adm. Code 1220.421. Ads must be truthful and not misleading. Dentists may not claim superior quality, advertise pain-free dentistry, or offer gifts. Because Illinois issues specialty licenses, specialty words require a license or a disclaimer. Ads must be kept for 3 years.
- Illinois licenses specialties: terms such as "orthodontist" or "periodontist" may be used only by dentists who hold an Illinois specialty license.
- Disclaimers are mandatory: general dentists using specialty-type language, including "cosmetic dentistry" or "implant dentistry", must disclose that they are licensed as general dentists.
- Five outright bans: superior-quality claims, "painless" claims, undisclosed paid referral services, gifts as inducements, and "sedation dentistry" without a permit.
- Records rule: keep a copy of every ad for 3 years; TV, radio and internet ads must be prerecorded, approved and retained.
- Every practice welcome — retainers from $499/mo, Goals-Driven engagements, Performance-Linked Payout Models available.

“They were able to get all my ideas and work with me over a period of three to four months and create this amazing website. It's super customized, very modern, and it incorporates all the elements that I had wanted — the patient portal, nice pictures, a very interactive website, patient reviews. I would highly recommend their company to anyone who wants to make an excellent website.”
Which Illinois laws govern dental advertising?
Two layers apply. Section 45 of the Illinois Dental Practice Act (225 ILCS 25/45) sets what dentists may advertise and lists unlawful practices. The Illinois Department of Financial and Professional Regulation (IDFPR) adds detail in 68 Ill. Adm. Code 1220.421, last amended effective September 10, 2024. Both apply to every medium, including websites and social media.
Section 45 says its purpose is to give the public "a sufficient basis upon which to make an informed selection of dentists" while protecting against false or misleading ads. The Act itself was due to sunset on January 1, 2026. The current compiled text now shows a repeal date of January 1, 2031, after Public Act 104-151. Section 45 was last amended by P.A. 103-628, effective July 1, 2024.
What Illinois dental ads may contain
- Services offered, the dentist's name, title, office hours, address and phone.
- Area of specialization, including appropriate board certification or limitation of practice.
- Schools attended, hospital affiliations, professional society memberships and foreign languages (Rule 1220.421(b)).
- Credit arrangements and acceptance of Medicare or Medicaid patients.
- Usual and customary fees for routine services, with a note that fees may be adjusted for complications or unforeseen circumstances.
- Office features such as accessibility and parking, and any other information a reasonable person might find relevant.
This summary reflects the text we reviewed in October 2026. Confirm current wording with your counsel before launching a campaign.
What can an Illinois dentist not say in an ad?
Section 45 makes five practices unlawful. Dentists may not use claims of superior quality of care, advertise dentistry "without causing pain", pay an undisclosed dental referral service, offer gifts to secure patients, or use "sedation dentistry" without a current anesthesia or sedation permit. False claims, guarantees and appeals to vanity or fear are also barred.
| Common ad phrase | Illinois status | Safer alternative |
|---|---|---|
| "The best dental care in Chicago" | Superior-quality claim, unlawful under § 45(1) | "Same-week appointments and evening hours" |
| "Painless dentistry" | Unlawful under § 45(2) | "We explain comfort and numbing options before treatment" |
| "Sedation dentistry available" | Lawful only with a general anesthesia, deep sedation or moderate sedation permit under § 8.1 | Name the permit holder, or describe other comfort options |
| "Free electric toothbrush with every new-patient visit" | Gift as an inducement, unlawful under § 45(4) | A free exam, with no charge for other services that visit |
| "Guaranteed results" | Guarantee of success, barred by § 45 and Rule 1220.421(d)(2) | Describe the process and what to expect |
| "Don't let a crooked smile ruin your life" | May play on fears or vanity | Neutral benefit language |
The free-exam rule
Illinois explicitly allows free examinations and free dental services. The catch is strict: a dentist may not charge a new patient for any dental service provided at the time of the free exam or free service. If the free exam turns into same-day X-rays or a cleaning, those must also be free.
Rule 1220.421(d) adds that misleading content includes omitting material facts, creating unjustified expectations, exaggerating quality of care, and advertising services the dentist is not licensed to provide.
How do specialty licenses change Illinois dental marketing?
Illinois issues separate dental specialty licenses on top of the general dental license. Under 225 ILCS 25/11(b), no dentist may hold out as a specialist unless licensed in that specialty. Words such as "specialist", "practice limited to" or "limited to specialty of", with a specialty name, are prima facie evidence of holding out as a specialist.
Titles reserved for specialty license holders
Rule 1220.421(f) lists words a dentist cannot use unless licensed in that specialty: Endodontist, Pedodontist, Pediatric Dentist, Periodontist, Prosthodontist, Orthodontist, Dentist Anesthesiologist, Oral and Maxillofacial Radiologist, and Oral and Maxillofacial Surgeon.
Three disclaimer rules
- Specialty services by a general dentist: Section 45 requires any ad announcing endodontics, pediatric dentistry, periodontics, prosthodontics, orthodontics, oral surgery or oral and maxillofacial radiology by a dentist not licensed in that specialty to state that the dentist does not hold that specialty license.
- Specialist-style wording: a general dentist using words customarily used by specialists must include a prominent disclaimer that he or she is licensed only as a general dentist (Rule 1220.421(f)).
- Non-recognized "specialties": Rule 1220.421(h) says language suggesting a specialty not recognized in Rule 1220.310 needs a disclaimer. Its examples are family, cosmetic, restorative, preventive, hospital and implant dentistry, TMJ and craniomandibular dentistry.
That third rule surprises many practices. A homepage headline reading "Cosmetic and Implant Dentistry" needs a disclaimer stating the specialties the dentist is licensed in, or that the dentist is licensed as a general dentist in Illinois. "Board certification" may be advertised, but only where it is accurate and does not imply an Illinois specialty license the dentist lacks.
What extra rules apply to Illinois group practices and DSOs?
A practice operating under a fictitious or assumed name must designate a licensed Illinois dentist at each location who is responsible for all advertising. That dentist's name, office address and phone must appear in all advertising. Owners' names must appear too, if they differ from the designated dentists.
The Rule 1220.421(e) requirements
- A designated, Illinois-licensed dentist at each practice location takes responsibility for advertising in Illinois.
- The designated dentists' names, office address and office phone appear in all ads for the entity.
- Owners' names appear in all ads if the owners are not the designated dentists.
- A list of all dentists who perform services is displayed prominently at each location.
- If the entity offers general dentistry and a licensed specialty, specialty ads name the licensed specialist who performs that service.
For multi-location groups, Section 45 also requires practices enrolled in a managed care network to verify, electronically or in writing, whether each provider is accepting new patients at each listed location. Keep plan directories accurate, since outdated listings send patients to the wrong office.
Record-keeping for digital ads
Section 45 requires a copy of every ad for 3 years, showing the accurate date and place of publication. Rule 1220.421(c) adds that TV, radio and internet ads must be prerecorded and approved by the dentist, with a recording kept for at least 3 years. The dentist must supply a copy within 7 working days of a written request.

How do Illinois rules apply to referral services, lead generation and non-dentist advertisers?
Section 45(3) makes it unlawful for a dentist to pay a dental referral service, or a third party that advertises one, unless all of that service's advertising makes clear that dentists pay a fee for the referral. Section 45 also says the Act does not authorize advertising of dental services when the offeror is not a dentist.
What that means for lead generation
- Directory and booking platforms: if a platform presents itself as helping patients "find a dentist" and you pay per lead or per booking, check whether its advertising discloses that dentists pay. If it does not, the risk sits with you as the paying dentist.
- Third-party landing pages: "find a local implant dentist" pages run by lead sellers can look like referral services. Ask how they disclose payment before you buy leads.
- Your own ads: paying for Google Ads or Meta ads in your own name is ordinary advertising, not a referral service.
Management companies and DSOs
Because Section 45 does not authorize advertising by a non-dentist offeror, the conservative approach is that a management company should not appear as the advertiser of record for dental services. Ask counsel how this applies to your structure. The ads should run under the practice, with the designated dentist named as Rule 1220.421(e) requires. Review who owns the ad accounts, whose name appears in the ads and who approves copy.
Superiority claims in reviews and AI answers
Section 45(1) bars claims of superior quality used "to entice the public". A patient review that says "best dentist in Naperville" is the patient's opinion. But if the practice puts that quote in an ad headline, it becomes the practice's claim. Keep review quotes factual when you use them in paid ads, and keep practice pages free of "best" language that AI engines may repeat.
What should an Illinois dental practice check across its website, ads, GBP and social?
Use the checklist below before anything goes live. The specialty disclaimer and the 3-year archive are the two items that are easiest to overlook. For profile setup, see our dental Google Business Profile guide. To compare another state's approach, read the Virginia Board of Dentistry advertising guide.
| Channel | Check | Illinois basis |
|---|---|---|
| Website | Specialist titles only for specialty license holders; general-dentist disclaimer on cosmetic, implant and other specialty-style pages | 225 ILCS 25/11(b); Rule 1220.421(f)-(h) |
| Website and ads | No "best", "painless" or "guaranteed" claims | § 45(1), (2); Rule 1220.421(d) |
| Fee ads | Routine-service fees carry the "may be adjusted" note unless fees never vary | § 45(d); Rule 1220.421(b)(9) |
| Offers | No gifts; free exams mean no charge for other services that visit | § 45(4) |
| Sedation pages and ads | Permit verified before using "sedation dentistry" | § 45(5); § 8.1 |
| Google Business Profile | Name and categories match the licensed scope; disclaimer in the description if specialty-type terms appear | Rule 1220.421(f)-(h) |
| Social and video | Internet video approved and archived for 3 years; date and place recorded | § 45; Rule 1220.421(c) |
| Assumed-name entities | Designated dentist and owners named in every ad | Rule 1220.421(e) |
Testimonials are not addressed by name in Section 45 or Rule 1220.421, as far as we found. They still must not create unjustified expectations, and the FTC rule on reviews and testimonials applies nationwide. Use real, authorized reviews only.

Common questions
Can a general dentist in Illinois advertise orthodontics or implants?
Yes, with a disclaimer. Under 225 ILCS 25/45, an ad announcing orthodontics or another listed specialty by a dentist not licensed in it must state that the dentist does not hold that specialty license. Rule 1220.421(h) also requires a disclaimer for terms like "implant dentistry" or "cosmetic dentistry". Confirm wording with counsel.
Are free exams allowed in Illinois dental advertising?
Yes. Section 45 of the Illinois Dental Practice Act allows dentists to advertise free examinations or free dental services. However, a dentist may not charge a new patient for any dental service provided at the time of the free exam or free service. Gifts offered as an inducement to secure patients remain unlawful.
Can an Illinois dentist advertise "sedation dentistry"?
Only with the right permit. Section 45(5) makes it unlawful to use "sedation dentistry" or similar terms unless the advertising dentist holds a valid, current IDFPR permit to administer general anesthesia, deep sedation or moderate sedation under Section 8.1 of the Act. Check the permit status before publishing any sedation page or ad.
How long must Illinois dentists keep copies of advertisements?
Three years. Section 45 requires a copy of all advertisements for 3 years, each showing the accurate date and place of publication. Rule 1220.421(c) adds that TV, radio and internet ads must be prerecorded and approved, with recordings kept at least 3 years and supplied within 7 working days of a written request.
Is the Illinois Dental Practice Act still in force after its 2026 sunset date?
Yes, based on the current compiled statutes we reviewed. The Act was scheduled for repeal on January 1, 2026, but Public Act 104-151 moved the repeal date to January 1, 2031, and the compiled sections now show the 2031 date. Section 45 on advertising remains in effect. Confirm current status on the General Assembly site.
