Usually not, for a med spa. A dentist’s license covers dentistry as your state defines it, generally the mouth, jaws and their adjacent structures. A med spa medical director directs the practice of medicine across your whole menu and delegates it to NPs, PAs and RNs. Tennessee’s med spa rule requires an MD or DO. Florida’s clinic statute lists physician licenses, and dentistry is not among them.
Two licenses, two definitions
Every state defines dentistry by anatomy and purpose. Florida’s definition is typical: dentistry is “the healing art which is concerned with the examination, diagnosis, treatment planning, and care of conditions within the human oral cavity and its adjacent tissues and structures” (Fla. Stat. 466.003(3)). Tennessee’s 2003 definition, as quoted by its Attorney General, reaches “diseases, disorders and/or conditions of the oral cavity, maxillofacial area and/or the adjacent and associated structures.”
A med spa medical director does something else. The director approves protocols, delegates treatments to nurses and advanced practice clinicians, and answers for the clinical program. Neurotoxin in the forehead, a laser on the legs and a weight-management prescription all sit inside that program. The nurse practitioner vs physician page explains the same distinction for NPs. The logic for dentists is the same: the question is what the license covers.
Injecting and directing are separate questions
Most searches on this topic blur two things. Whether a dentist may inject neurotoxin or filler is a dental scope question, and several states answer yes within the oral and maxillofacial region. Whether a dentist may direct a med spa is a question about who may authorize medical treatment by other people.
The second question turns on the nurses’ licenses as much as the dentist’s. In Florida, the practice of professional nursing includes administering treatments “as prescribed or authorized by a duly licensed practitioner authorized by the laws of this state to prescribe such medications and treatments” (Fla. Stat. 464.003). A dentist is authorized to order dental treatment. An order for a treatment outside dentistry has no dental authority behind it, and the nurse who carries it out is exposed along with the dentist.
Tennessee: the med spa rule names MD or DO
Tennessee answers the director question in its med spa rule. Rule 0880-02-.24 says the medical director or supervising physician “must be a medical doctor or osteopathic physician with an active Tennessee license and an active medical practice in Tennessee,” and that physician attests to responsibility for the cosmetic medical services at the spa. The Board of Medical Examiners’ FAQ adds that active practice means a physical location in Tennessee, “not a solely telemedicine practice.” A dentist cannot hold the registration. The Tennessee registry post covers what the public listing shows.
On injecting, Tennessee is more open than its med spa rule suggests. Attorney General Opinion 14-51 (April 2014) concluded that the dental practice definition is broad enough to cover neurotoxin and filler injected into the oral cavity, maxillofacial area and adjacent structures by a trained dentist, for therapeutic or cosmetic purposes, and that the Board of Dentistry may permit it by rule. The Board’s specialty rule, 0460-02-.06(9)(c), lists “Lip augmentation” and “Botox injections or future FDA approved neurotoxins” among oral and maxillofacial surgery procedures, and (9)(d) makes performing them without the qualifications grounds for discipline.
Florida: the clinic statute lists four physician licenses
Florida’s dental definition stops at the oral cavity and its adjacent tissues and structures. Its definition of oral and maxillofacial surgery covers “the functional and esthetic aspects of the hard and soft tissues of the oral and maxillofacial regions” (466.003(14)). We found no Florida Board of Dentistry rule or declaratory statement on cosmetic neurotoxin or filler by general dentists.
For the director role, the clinic statute is direct. A “medical director” is a physician licensed under chapter 458, 459, 460 or 461 (Fla. Stat. 400.9905(5)): allopathic, osteopathic, chiropractic and podiatric physicians. Chapter 466, dentistry, is not on the list. The same subsection allows a “clinic director” only where the clinic does not provide services under those physician practice acts, and it adds that a practitioner “may not serve as the clinic director if the services provided at the clinic are beyond the scope of that practitioner’s license.” Under 400.9935(1), whoever holds the role accepts legal responsibility in writing for licensure checks, records and billing review. See Florida clinic licensure for which businesses need the license at all.
One Florida detail you may hear: section 464.012(3) lists a practitioner licensed under chapter 466 among those who may maintain supervision of an APRN protocol. That lets a dentist supervise an APRN. It does not appear to enlarge what the dentist may supervise. Florida medical director requirements cover the physician route.
Arizona and Maryland: dental boards that have spoken
Arizona wrote dental injectables into statute. A.R.S. 32-1202 defines the practice of dentistry to include “administering botulinum toxin type A and dermal fillers to the oral maxillofacial complex for therapeutic or cosmetic purposes.” That is the clearest authorization we found, and it is still bounded by anatomy.
Maryland’s Board of Dental Examiners took the definition route. Its August 2012 bulletin says a dentist may use prescribed drugs “as long as the treatment is within the aforementioned scope of practice,” meaning the Health Occupations 4-101 definition tied to a tooth, gum, jaw and associated structures, and that the dentist must be competent under COMAR 10.44.32. Neither state’s text turns a dentist into the director of a medical practice.
| State | May a dentist inject neurotoxin or filler? | Who may direct a med spa | Authority |
|---|---|---|---|
| Tennessee | Oral and maxillofacial surgery specialty rule lists Botox and lip augmentation; AG says the Board may extend it to trained general dentists by rule | MD or DO, active Tennessee license and in-state practice | Rule 0880-02-.24; Rule 0460-02-.06(9); AG Op. 14-51 |
| Florida | No board rule located; definition stops at the oral cavity and adjacent structures | Medical director licensed under ch. 458, 459, 460 or 461; dentists not listed | Fla. Stat. 466.003; 400.9905(5); 400.9935 |
| Arizona | Yes, to the oral maxillofacial complex, therapeutic or cosmetic | Not addressed by the dental statute | A.R.S. 32-1202 |
| Maryland | Only within the dental definition, with documented competence | Not addressed by the bulletin | Board bulletin (2012); H.O. 4-101; COMAR 10.44.32 |
As of October 2026. Dental scope moves by statute and board rule, so confirm the current text in your state.
Where MDside stands
Florida’s list includes chiropractic and podiatric physicians. MDside places only MD and DO physicians as med spa medical directors, in every state. Your menu runs on prescription drugs, physician delegation and good faith exams, and we want the director’s license to cover every line of it without an argument. A dentist on your team can still inject within dental scope where the state allows. The physician directs the rest.
What this means for you
If a dentist is named as your med spa’s medical director, replace that arrangement with an MD or DO before your next registration or renewal. In Tennessee, the registry entry itself must name a physician. In Florida, check whether your clinic needs an AHCA license and confirm that the named director holds one of the listed physician licenses. If a dentist injects at your spa, document that the work falls within that state’s dental scope, and keep the dentist off the protocols that govern your nurses. MDside supplies physician medical directors and the delegation paperwork for med spa owners.

Frequently asked questions
Can a dentist be a medical director of a med spa?
Generally no. A dentist’s license covers dentistry, defined by each state around the oral cavity, jaws and adjacent structures. A med spa medical director authorizes and delegates medical treatment across the whole menu. Tennessee requires an MD or DO for the role, and Florida’s clinic statute defines a medical director by physician licenses that do not include dentistry.
Can a dentist be a medical director in Tennessee?
Not for a med spa. Tennessee rule 0880-02-.24 requires the medical director or supervising physician to be a medical doctor or osteopathic physician with an active Tennessee license and an active Tennessee practice. The Board of Medical Examiners says active practice means a physical location in the state, not a solely telemedicine practice. The physician attests to responsibility for the spa’s cosmetic services.
Can a dentist be a medical director in Florida?
Florida’s clinic statute defines a medical director as a physician licensed under chapter 458, 459, 460 or 461. Dentistry is chapter 466 and is not listed. A clinic director may serve only where the clinic provides no services under those physician acts, and never where the clinic’s services exceed that practitioner’s license.
Can a dentist do Botox outside the mouth?
It depends on the state, and the boundary is anatomical. Arizona’s statute allows neurotoxin and filler to the oral maxillofacial complex for therapeutic or cosmetic purposes. Tennessee’s Attorney General read its dental definition to cover the maxillofacial area and adjacent structures. Maryland ties any use to the dental definition and documented competence. None extends to the rest of the body.
