How to choose a dentist
The vetting playbook: what the letters after a dentist's name actually mean, how to check a Tennessee license and discipline record in a few minutes, how to read reviews without getting played, whether a corporate chain or an independent office serves you better — and the questions that reveal how a practice really treats its patients.
Start with the license, not the logo: verify any Tennessee dentist free at the state's Licensure Verification portal before you book. DDS and DMD are the same degree, only 12 specialties are officially recognized, and “cosmetic dentist” is a marketing label, not a credential. Then judge the office by how it answers your questions.
How this page works: every rule, number, and requirement below is cited to its source — the ADA, the Tennessee Board of Dentistry, the FTC, or attorney-general and ethics records. Where the evidence is genuinely two-sided, we say so. Where we couldn't verify something, we left it out rather than dress it up.
Credentials decoded: what the letters actually mean
Dentistry uses a small alphabet of credentials, and a few of them mean less than they sound. Here's the whole set — what each one proves, what it doesn't, and how to check it.
DDS vs. DMD — there is no difference
This is the question patients ask most, and it has a clean answer. The American Dental Association's official position: “The DDS and DMD are the same degrees. Dentists who have a DMD or DDS have the same education. It's up to the universities to determine what degree is awarded, but both degrees use the same curriculum requirements.” DDS stands for Doctor of Dental Surgery; DMD for Doctor of Dental Medicine. The two names come from university tradition, not different training — the first DDS was awarded in 1840, and Harvard coined the DMD when it founded its dental school in 1867, following its Latin degree-naming custom. Roughly a third of U.S. dental schools award the DMD (an estimate; the rest award the DDS).
What actually guarantees the training is the accreditor behind the school. There is exactly one: the Commission on Dental Accreditation (CODA). Every accredited school must meet the same academic and clinical standards whichever degree it grants, all graduates must pass the same National Board examinations, and state licensing boards accept either degree as equivalent. So when you're comparing two dentists, ignore the letters and look at the license, the specialty training, and the track record.
| Credential | What it actually means | How to check it |
|---|---|---|
| DDS or DMD | The dental degree itself. Identical education and curriculum requirements; the university picks the name. Says nothing by itself about skill or specialty training. | Confirm the school was CODA-accredited — then verify the license below, which is the check that counts. |
| Tennessee dental license | The legal permission to practice dentistry in Tennessee, issued by the Tennessee Board of Dentistry. To earn it by examination, a dentist must pass a regional clinical exam (with prosthetic, periodontal, endodontic, and restorative components), the National Board examination, and the Board's own Ethics and Jurisprudence exam. | The state Licensure Verification portal — see the walkthrough in the next section. |
| Specialty training | Completion of an accredited residency in one of the 12 recognized specialties listed below — extra years of focused training beyond dental school. | Ask where the residency was done and in which specialty. The specialty should be one of the 12. |
| Board certification | A separate, voluntary credential: after residency, the specialist passed the certifying board's examinations demonstrating advanced clinical competency. It is not the same as being a specialist — a dentist can practice a recognized specialty without it. | The specialty's certifying board (listed in the table below) — most keep a public “find a diplomate” directory. |
| Sedation / anesthesia permit | Tennessee requires any dentist who uses conscious sedation, deep sedation, or general anesthesia to hold a Board permit — and the facility where it's given needs its own permit too. More in the sedation section below. | Ask the office who holds the permit and when the facility was last inspected. |

The 12 recognized specialties — the complete list
Specialties are recognized by the National Commission on Recognition of Dental Specialties and Certifying Boards (NCRDSCB). There are exactly twelve. If a dentist advertises a specialty that isn't on this list, the title is marketing, not a recognized credential.
| Specialty | What they do | Certifying board |
|---|---|---|
| Dental Anesthesiology | Sedation and pain control for dental procedures | American Dental Board of Anesthesiology |
| Dental Public Health | Community and population oral health — programs, prevention, policy (rarely chairside care) | American Board of Dental Public Health |
| Endodontics | Root canals and the inside of the tooth (the pulp) | American Board of Endodontics |
| Oral and Maxillofacial Pathology | Diagnosing diseases of the mouth and jaws — biopsies, lesions, sores that don't heal | American Board of Oral and Maxillofacial Pathology |
| Oral and Maxillofacial Radiology | Interpreting dental imaging — X-rays, 3D CBCT scans | American Board of Oral and Maxillofacial Radiology |
| Oral and Maxillofacial Surgery | Extractions, jaw surgery, implants, facial trauma | American Board of Oral and Maxillofacial Surgery |
| Oral Medicine | Medical conditions that show up in the mouth, and dental care for medically complex patients. The newest specialty — recognized in March 2025 | American Board of Oral Medicine |
| Orofacial Pain | Jaw-joint (TMJ/TMD) disorders, facial pain, and related headaches | American Board of Orofacial Pain |
| Orthodontics and Dentofacial Orthopedics | Braces, clear aligners, bite alignment | American Board of Orthodontics |
| Pediatric Dentistry | Dental care for infants, children, and adolescents | American Board of Pediatric Dentistry |
| Periodontics | Gums and the bone supporting the teeth; also places implants | American Board of Periodontology |
| Prosthodontics | Crowns, bridges, dentures, and full-mouth reconstruction — the specialty with formal esthetic (cosmetic) training | American Board of Prosthodontics |

“Cosmetic dentist” is not a specialty
It appears nowhere on the list above, which means any dentist — with any level of training — can put it on a sign or a website. That doesn't make the work bad; plenty of general dentists do excellent cosmetic work. It means the label itself proves nothing. If cosmetic results are what you're buying (veneers, a smile redesign), ask what training and how many cases stand behind it — or look for a prosthodontist, the recognized specialty whose residency covers exactly this work.
Check the license: a five-minute walkthrough
Every Tennessee dentist's license status, expiration date, and disciplinary history is public, free, and searchable. This is the single most useful vetting step on this page — do it before the first appointment, not after a bad one.
- Open the portal. Go to the Tennessee Department of Health's Licensure Verification portal: internet.health.tn.gov/Licensure.
- Set the profession. Choose “Dentist” (the same portal covers dental hygienists and registered dental assistants — useful if you want to check the rest of the team).
- Search. You can search by name, by city, or by license number. If a name search finds nothing, try the last name only — the system needs an exact spelling match, and hyphenated or suffix-bearing names often trip it up.
- Open the record and check three things. (1) License status — you want “active.” (2) Expiration date — in the future. (3) Disciplinary history — past Board actions are shown on the record. A clean record is the norm; a decades-old resolved action with context is different from a recent one.
- Make sure it's the right person. Match the city and, if the office gave you one, the license number. Common names have namesakes — confirm you're reading your dentist's record, not a stranger's.
What keeps that license current
Tennessee dentists must complete 40 hours of continuing education every two years to renew — the cycle runs January 1 of an odd-numbered year through December 31 of the next even-numbered year. At least 2 of those hours must cover chemical dependency, and all licensees must keep current CPR certification. Dentists holding sedation permits owe extra training on top (see the sedation section).

If something goes wrong
Complaints about a Tennessee dentist go to the Department of Health's Office of Investigations: (800) 852-2187. The Tennessee Board of Dentistry itself is at 665 Mainstream Drive, Nashville, TN 37243, (615) 532-3202 — the Board's page is at tn.gov/health/dentistry-board.
One honest limit: a license check tells you a dentist is legal and whether the Board has acted. It cannot tell you whether their crown margins are beautiful. That's what the rest of this page is for.
Reading reviews without getting fooled
Reviews are genuinely useful — for patterns. They are nearly useless one at a time. Here's how to extract the signal and ignore the theater.
First, some ground rules that are now law. The FTC's rule on fake reviews and testimonials took effect October 21, 2024 (16 C.F.R. Part 465). It bans fake or AI-generated reviews, reviews from people who never used the business, buying or selling reviews tied to a positive or negative sentiment, insider reviews from owners and staff without disclosure, and review suppression — burying or filtering out negative reviews while presenting the rest as the full picture. Violations can draw civil penalties of roughly $52,000–$53,000 per violation. The law helps, but enforcement lags; your own reading habits still matter.
| Signal | How to read it |
|---|---|
| The same theme, over and over | The most reliable signal in any review profile. Fifteen strangers independently mentioning gentle hygienists, surprise bills, or 45-minute waits are telling you something true about how the office runs — whatever the star average says. |
| Nothing but five stars, zero criticism | A reason for skepticism, not confidence. Real practices accumulate a few unhappy reviews over hundreds of patients. The FTC treats suppressing unfavorable reviews as deceptive — a spotless profile can mean good care, aggressive filtering, or both. |
| One furious review | Low weight on its own — every practice has one, and you can't verify the story. It only starts to matter when it rhymes with others. |
| Reviews on more than one platform | Cross-check Google against at least one other source (Yelp, Healthgrades, your insurer's directory). A theme that survives across platforms with different review pools is much harder to manufacture. |
| How the office answers criticism | A calm, specific reply that invites the patient to call is a good sign. A defensive or copy-pasted reply — or silence on every negative review while thanking every positive one — tells you how complaints get handled when they're yours. |
The FTC points are from the rule itself (16 C.F.R. Part 465, effective October 21, 2024). The reading guidance is standard consumer advice — ours, labeled as such, not a sourced finding.
Corporate chain or independent practice? The honest version
Neither model guarantees a good or bad dentist. What differs is who controls the business — and what pressure that puts on the person holding the drill. Here's what the record shows, including the parts that don't fit a simple story.
Many branded dental offices are supported by a dental service organization (DSO) — a management company that handles scheduling, billing, HR, marketing, and purchasing for practices that are nominally owned by individual dentists. Tennessee law is unusually direct here: under T.C.A. § 63-5-121, the owner of an active dental practice must be a Tennessee-licensed dentist, and a dentist generally can't practice as an employee of an entity that isn't primarily engaged in dentistry. That's why the chain model runs through dentist-owners plus management contracts — and why the name on the building often doesn't tell you who actually runs the place. Asking “Who owns this practice?” is a fair question with a checkable answer.
| Figure | Value | What it means |
|---|---|---|
| U.S. dentists affiliated with a DSO, 2024 | 16.1% | Roughly 1 in 6 dentists — more than double the share in 2015. |
| Dentists within 10 years of graduating who are DSO-affiliated, 2024 | 26.5% | Newer dentists are joining chains at the highest rate — expect the model to keep growing. |
| Dentists who own their practice | 84.7% → 72.5% | Share fell from 2005 to 2023 as employment models spread. |
| Dentists affiliated with private-equity-backed groups | 6.6% → 12.8% | Share rose from 2015 to 2021, per ADA research. |
These are national figures. Tennessee-specific DSO penetration wasn't available from the ADA data we reviewed, and we won't extrapolate a national number onto Tennessee.
The case against the chain model — from the record
Two attorney-general cases define the documented risk. In New York (2015), the AG investigated Aspen Dental Management after more than 300 consumer complaints — quality of care, billing, misleading advertising, upselling — and found the management company coached dentists on patient care, paid bonuses to office managers and hygienists to sell more treatments, scolded offices that missed revenue targets, and shared in clinic profits. Aspen paid a $450,000 civil penalty.
In California, the AG's settlement reached $2.3 million over allegations that included $50–$100 incentive payments to hygienists for clear-aligner sales, deceptive marketing, and a non-practicing “straw” dentist-owner who lived out of state. California responded with SB 351 (effective January 1, 2026), which bars private-equity firms and hedge funds from imposing patient quotas, restricting the procedures dentists may offer, or limiting dentist–patient time.
The pattern to notice isn't the brand name — it's sales incentives attached to clinical staff. That can exist in any ownership model, but it is what regulators found when they looked hardest at chains.
The honest upside — and the independent trade-offs
The DSO model's legitimate advantage is real: centralized administrative support takes scheduling, billing, insurance paperwork, and compliance off the dentist's plate, which can mean more chair time and less chaos. Chain offices also tend to have standardized systems behind them.
Independent practices offer a different kind of accountability: the dentist whose name is on the door owns the clinical decisions and the business, answers for both, and usually plans to see you for decades. The trade-off is that a solo office has thinner coverage when the dentist is away and fewer in-house resources for complex cases.
Our bottom line: vet the dentist and the office's incentives, not the category. A chain dentist who explains options and tolerates “let me think about it” beats an independent who pressures you — and the reverse is equally true.
Questions to ask at a first visit
The ADA's own consumer guidance starts one step earlier than most people expect: schedule consultation time to meet the dentist and staff before booking treatment, bring your records and a written list of questions, and notice whether the office is welcoming, comfortable, and neat. Then ask these.
- “Will you teach me how to prevent problems?” The ADA's first screening question: does this dentist explain ways to prevent dental disease and provide dental-health instruction — or only fix what's broken?
- “How do emergencies work after hours?” Ask how the dentist and staff handle emergencies outside of office hours. A real answer names a phone number, an on-call rotation, or a partner office — not a shrug.
- “Do you know my benefit plan, and what are my payment options?” Is the staff familiar with your dental plan, and do they offer financial options for treatment costs? Offices that bill insurance daily will answer fluently.
- “Will my history go into a permanent file?” Your medical and dental history should be recorded and kept in a permanent record. It's the baseline of a practice that tracks you over time.
- “I'm anxious — how do you handle that?” Say it plainly. The ADA encourages patients to share past dental experiences and concerns, including anxiety, and to expect the dentist to listen and answer every question. Watch whether they rush you or slow down.
- “If I need sedation, who holds the permit?” In Tennessee, sedation beyond a minimal level requires a Board permit for the dentist and a permit for the facility. An office with its paperwork in order will answer without blinking.
- “Can this plan be phased?” Ask what is urgent now, what can wait a year, and what you're simply watching. A dentist who sorts a plan into “now / later / watch” is thinking like your partner, not a salesperson.
The ADA's standard for what you're looking for
In the ADA's words, choose a dentist who can be “a coach to motivate you, a trusted advisor to turn to when health issues arise and a partner to make dental care decisions with.” Hold the first visit to that standard — including if you've stayed away for years and feel embarrassed about it. Sharing that concern out loud, and being met with listening instead of a lecture, is itself one of the most reliable tests on this page.
Red flags: upselling and overtreatment
The ADA's ethics code is unusually blunt about this, and it applies to every dentist in every practice model. Section 5.B.6, “Unnecessary Services”: “A dentist who recommends or performs unnecessary dental services or procedures is engaged in unethical conduct… regardless of the type of practice arrangement or contractual obligations.” That last clause covers employed and chain dentists explicitly. These are the patterns that should slow you down.
A “specialty” that isn't one of the 12
“Cosmetic dentist,” “implantologist,” and similar titles are marketing labels, not recognized credentials. Real specialty training means an accredited residency in one of the 12 specialties in the table above. When a title can't be matched to the list, ask what training stands behind it.
A huge plan at a first visit, with pressure to start today
A new dentist who has never seen your history presenting a five-figure plan — and urgency to begin immediately — is the classic overtreatment setup. Get a second opinion before committing, especially when the new plan finds many problems a previous dentist never mentioned.
Staff who sell
When hygienists or office managers are paid bonuses tied to selling treatment, recommendations stop being pure clinical judgment. That incentive structure is exactly what the New York and California attorneys general documented at a major chain. If the pitch comes from everyone in the building, ask why.
Won't show you the evidence
You are entitled to see your own X-rays and have the dentist point at the tooth and explain what's being treated. Vague findings (“lots of decay everywhere”) with nothing shown on the image is a flag — honest diagnoses survive being pointed at.
Fees that grow because you have insurance
The ADA ethics code (§5.B.1) calls it unethical to raise a fee solely because a patient has a benefits plan — and §5.B.4–5 do the same for misdescribed procedures or incorrect dates on claim forms. If two quotes for the same work differ wildly depending on how you pay, ask for both in writing.
Undisclosed financial interests
Under §5.C of the ADA ethics code, dentists must disclose monetary conflicts of interest. If a dentist steers you to one specific product, lab, or financing product, you're entitled to ask whether they have a financial relationship with it.
The practical defense
None of this requires an argument in the chair. Ask for the diagnosis and plan in writing, take your X-rays (they're your records), and get a second opinion on any large non-emergency plan. A dentist confident in a diagnosis expects that on big cases — and a treatment plan that can't survive a second pair of eyes wasn't one you wanted anyway.
If sedation matters to you: levels and Tennessee's rules
For anxious patients, sedation is often the difference between care and avoidance — so know what the levels mean and what Tennessee requires of the offices offering them. No sedation is risk-free; the point of the rules below is that the risk is managed by trained, permitted people in inspected facilities.
| Level | What it means (ADA definitions) | Common example |
|---|---|---|
| Minimal sedation | You respond normally to verbal commands; airway, breathing, and cardiovascular function are unaffected. | Nitrous oxide (“laughing gas”) alone |
| Moderate sedation | You respond purposefully to verbal commands, alone or with light touch; no help is needed to keep your airway open, breathing is adequate, and cardiovascular function is usually maintained. | Oral or IV sedation |
| Deep sedation / general anesthesia | Deeper levels on the same continuum, where responsiveness and airway protection are progressively reduced and monitoring demands rise sharply. | Hospital-grade anesthesia settings and advanced surgical cases |
One caution from the ADA's own guidelines: nitrous oxide combined with sedative drugs can produce moderate sedation, deep sedation, or even general anesthesia — combinations are not automatically “just nitrous.” For scale: about 70% of dental practices that offer sedation use nitrous oxide (Academy of General Dentistry, citing the ADA).
What Tennessee requires — ask about these
- A permit for the dentist. Under T.C.A. § 63-5-108(g), any Tennessee dentist who uses general anesthesia, deep sedation, or conscious sedation must hold a Board permit.
- A permit for the facility, inspected every 5 years. The office itself needs a facility permit, which expires five years from issuance; the Board inspects the facility's equipment and drugs before an initial permit, and all sedation facilities are inspected once every five years.
- Emergency readiness. Permit holders must maintain required emergency equipment and medications, keep current ACLS certification (a pediatric dentist may substitute PALS), and complete at least 4 hours of anesthesia/sedation continuing education each renewal cycle.
So the two questions from the first-visit list — who holds the permit, and when was this facility last inspected? — are not small talk. They're the whole safety structure in one sentence.
Questions people actually ask us
The ones that come up when someone is choosing a dentist — asked the way people actually ask them.
Nothing that matters to you as a patient. The ADA's position is that the DDS (Doctor of Dental Surgery) and DMD (Doctor of Dental Medicine) are the same degree, with the same education and the same curriculum requirements — the university decides which name to award. Every U.S. dental school is accredited by the same body, the Commission on Dental Accreditation (CODA), and graduates of both programs take the same National Board examinations.
Use the Tennessee Department of Health's Licensure Verification portal at internet.health.tn.gov/Licensure. Search by the dentist's name, city, or license number and open the record: you want to see an active license with an expiration date in the future, plus the disciplinary history. If a search finds nothing, try the last name only — the system needs an exact spelling match. To report a concern, contact the Department of Health's Office of Investigations at (800) 852-2187.
No. Cosmetic dentistry is not one of the 12 specialties recognized by the National Commission on Recognition of Dental Specialties and Certifying Boards, so any dentist can use the label regardless of training. If you want formal esthetic training, look for a prosthodontist — that's the recognized specialty whose training covers crowns, veneers, and smile reconstruction.
It means the dentist finished specialty residency training and then passed the certifying examinations of that specialty's board — for example, the American Board of Orthodontics for orthodontists. It's a voluntary credential that goes beyond completing a residency, and it's separate from being licensed. A dentist can legally practice a recognized specialty without board certification, so it's a positive signal, not a requirement.
Not automatically — but the incentives deserve a look. Attorneys general in New York (2015) and California documented cases where a large chain's management company pressured offices toward revenue targets and paid staff bonuses to sell more treatment. Tennessee law requires a dental practice to be owned by a Tennessee-licensed dentist, but management companies still run the business side of many branded offices. Ask who actually owns the practice, and judge the individual dentist in front of you.
Look for patterns, not individual reviews. Since October 21, 2024, the FTC's rule on fake reviews has banned bought reviews, AI-written fakes, and businesses suppressing negative ones, with penalties of roughly $52,000–$53,000 per violation. Even so, treat a profile with nothing but five stars and zero criticism as a yellow flag, and weight themes that recur across many reviews and more than one platform.
A good one won't — and finding out is part of the first visit. The ADA's consumer guidance is to tell the dentist about past experiences and concerns, including anxiety and embarrassment, and to expect them to listen and answer your questions. If the first appointment feels like a scolding or a sales pitch, that's information: you can take your records to another office.
No. You can ask questions, decline any item, get the diagnosis and plan in writing, and phase treatment — urgent work now, the rest later. The ADA's ethics code (Section 5.B.6) states that recommending or performing unnecessary services is unethical for any dentist, whatever the practice arrangement. For any large, non-emergency plan, a second opinion is a normal, reasonable step.
Ask two questions: who holds the permit, and when was the facility last inspected? In Tennessee, a dentist who offers conscious sedation, deep sedation, or general anesthesia must hold a Board permit, the facility needs its own permit, and facilities are inspected once every five years. Permit holders must keep current ACLS certification (pediatric dentists may substitute PALS) and complete at least 4 hours of anesthesia and sedation continuing education each renewal cycle. No sedation is risk-free, and nitrous oxide combined with other sedatives can go deeper than “just laughing gas.”
