A dental therapist is a provider licensed state by state to deliver a state-set subset of dental care — in Minnesota, Maine, Arizona and Connecticut, the states whose supervision rules this page draws on, always under a dentist's supervision or a written agreement with one.
A dentist is state-licensed for the broader list — decay, damaged teeth, dental appliances, prescriptions.
Training, scope, supervision, where each role is licensed and pay all differ.
Here's the comparison.
Dental therapist vs dentist at a glance
A dentist and a dental therapist are both licensed to treat teeth, but they are not two versions of one job.
The training routes, the legal scope, the supervision structure and the settings each may work in are set differently — and for therapists, they are set separately by each state.
| Dentist | Dental therapist | |
|---|---|---|
| License | State dental license — usually a DDS or DMD from an accredited program plus written and clinical exams; requirements vary by state | A state dental-therapy credential: its own license in Minnesota, a Dental Therapist credential in Colorado, or an authority added to a hygiene license, as in Maine |
| Training | DDS or DMD from an accredited program; most programs require at least a bachelor's degree and science courses to apply | CODA's dental therapy standards set a floor of at least three academic years of full-time postsecondary instruction (adopted February 6, 2015) |
| Scope | BLS's typical duty list runs from removing decay and filling cavities to prescribing medications and making models for dentures | A shorter, state-set list — in Maine, listed procedures including simple cavity preparations and restorations and simple extractions |
| Supervision | Licensed in the state where they work | Under a dentist in Minnesota, Maine, Arizona and Connecticut: Minnesota requires supervision by a Minnesota-licensed dentist under a written collaborative management agreement, capped at five therapists per dentist |
| Where | Licensure applies wherever they practice, state by state | A growing number of states, including Minnesota, Maine and Colorado, frequently with setting limits |
| Pay data | BLS publishes wages — a $170,950 median for general dentists, May 2025 | No federal wage series in our research |
One asymmetry runs through the whole table: the dentist column describes a single licensure model applied state by state, while the therapist column is a patchwork — state statutes that do not agree with each other, plus one accreditor's national standard.
That is why each therapist entry names its source: a state's law or the accreditor's standard, not a rule that reads the same everywhere.
What can a dentist do that a dental therapist can't?
Start with the dentist's list, because it is the broad one.
Typical dentist duties listed by BLS include removing decay and filling cavities, repairing or removing damaged teeth, placing sealants, administering anesthetics, prescribing antibiotics or other medications, examining x-rays, and making models and measurements for dental appliances such as dentures.
A dental therapist's list is defined state by state, and it is shorter.
In Maine, a dental therapist may perform listed procedures — including simple cavity preparations and restorations and simple extractions — in limited practice settings under a written practice agreement and the general supervision of a Maine-licensed dentist.
Arizona's statute also names what therapists may not do: dispense or administer narcotic drugs, or independently bill any individual or third-party payor.
The prescribing line shows how the carve-up works — the dentist's list includes prescribing antibiotics or other medications, while Arizona's therapist statute puts narcotics off-limits by name.

And pairings matter: dentist vs hygienist is a different comparison with a different gap, and if the question is really hygienist vs therapist, that page owns it.
How the training paths differ
The therapist path runs through dedicated dental therapy education.
CODA's Accreditation Standards for Dental Therapy Education Programs — adopted February 6, 2015 — require at least three academic years of full-time postsecondary instruction or its equivalent.
State licensure then adds its own gates: Arizona requires graduation from a dental therapy program accredited (or initially accredited) by the ADA's Commission on Dental Accreditation, and Minnesota applicants must pass a comprehensive, competency-based clinical exam approved by the board plus a Minnesota jurisprudence exam.
The route, including the hygiene-license bridges Maine and Connecticut build in, is laid out in our guide to becoming a dental therapist.
The dentist path is the longer one, and it is layered.
Licensure usually requires a DDS or DMD from an accredited program plus written and clinical exams, with requirements varying by state — and most dental programs require applicants to arrive with at least a bachelor's degree and certain science courses before the professional program even starts.
Can a dental therapist become a dentist?
The licensure description in our sources is one route for every applicant — usually a DDS or DMD from an accredited program plus written and clinical exams, with each state adding its own requirements — and nothing in it branches by the license you hold today.
That includes the entry gates: most dental programs want applicants to arrive with at least a bachelor's degree and certain science courses before the DDS or DMD program even starts.
A therapist heading toward dentistry should plan on the full route, and confirm with individual programs and the state board how prior education counts.
Supervision: who works under whom
In Minnesota, Maine, Arizona and Connecticut — the states whose supervision rules this page draws on — a dental therapist's authorization is built on a named relationship with a dentist.
Minnesota requires dental therapists to practice under the supervision of a Minnesota-licensed dentist, mainly in settings serving low-income, uninsured and underserved patients or in a dental health professional shortage area, under a written collaborative management agreement — and one dentist may collaborate with no more than five dental therapists or advanced dental therapists.
Maine requires a written practice agreement with a licensed dentist.
The dentist's side of that relationship is spelled out too.
In Arizona, a dental therapist must complete 1,000 hours of clinical practice under a dentist's direct supervision before entering a written collaborative practice agreement, and a dentist may hold no more than four such agreements.
In Connecticut, a dentist may not hold collaborative agreements with more than two dental therapists at once — and is professionally responsible and legally liable for the therapist's authorized services.
The dentist's own license carries none of that architecture.
Dentists must be licensed in the state where they work — and the therapist statutes above route a therapist's authority through a dentist instead.
Where dental therapists are licensed
Dental therapy is authorized in a growing number of states, including Minnesota, Maine and Colorado — Colorado's dental board roster, for example, carries a Dental Therapist credential type.
No current national count of therapist states was verified for this article; the totals circulating online trace to secondary 2024 reporting and were not checked against statutes here, so this page names states rather than printing a number.
The authorization models also do not agree with each other, which matters when you compare the two careers across state lines.
Minnesota licenses dental therapists outright and restricts where they practice — mainly settings serving low-income, uninsured and underserved patients or shortage areas.
Maine runs therapy through the hygiene license as a "dental hygiene therapy" authority.
Connecticut goes a step further in that direction: a dental therapist there is a licensed dental hygienist authorized to practice dental therapy under a collaborative agreement, in a public health facility, under a dentist's general supervision.
For the role on its own terms — credential models, settings, day to day — the dental therapist career guide holds the detail.
And if you are mapping the state-licensed roles that sit around the dentist, dentist vs denturist is the neighboring comparison.

Dental therapist vs dentist salary
On the dentist side there is a federal number: BLS reported a May 2025 median annual wage of $170,950 for general dentists.
On the therapist side we found nothing equivalent — no separate dental therapist occupation in BLS wage data, and no federal dental therapist pay series.
A national dental-therapist salary figure you run across is therefore not a number to set beside the BLS median; our research found no federal series behind one.
For employers in therapist states, the practical consequence of that gap is that no federal benchmark anchors a dental therapist offer — job postings and local compensation data do the work a wage series otherwise would.
Our guide to hiring a dental therapist takes the employer side from there.
As a career decision, the comparison comes down to what each license unlocks.
The dentist path is longer — most dental programs want applicants to arrive with at least a bachelor's degree and certain science courses before the accredited program starts — and ends with the broader BLS duty list, prescriptions and dental appliances included.
The therapist path's accreditation floor is three academic years, and its scope and settings are what one state's statute says they are.
If you are weighing dentist careers against staying on the therapy side, browsing what practices actually post is the fastest reality check.
