Boolean search strings for dentists: DDS and DMD, residencies, specialty boards and the NPI Registry

A dentist search works when the string carries both degree spellings, DDS and DMD, the setting the client hires for, and a residency, board or procedure term that only a practicing dentist writes. Search "dentist" on its own and you get hygienists, dental assistants, office managers, dental students, DSO operations staff and the recruiters who place all of them. Licensure is also still state by state as of November 2026, so the license state belongs in the search plan from the start.

Below are ten strings by setting and specialty, the official sources behind each credential term, and what LinkedIn, Indeed and Google support as of November 2026. For the operators themselves, see Boolean search strings for recruiters; for the first call, see the dentist screening questions.

Degrees, residencies and boards that change what a dentist search finds

• DDS and DMD. The ADA's MouthHealthy page on DDS and DMD says the two degrees mean the same thing and use the same curriculum requirements, and that each university decides which one to award, as of November 2026. Put both, plus "doctor of dental surgery" and "doctor of dental medicine", in one OR block.
• Residencies. The Commission on Dental Accreditation's program search lists Advanced Education in General Dentistry (AEGD) and General Practice Residency (GPR) programs beside the specialty programs. They matter more in some states than others: New York's Office of the Professions says that since January 1, 2007 every applicant for initial licensure must complete an approved dental residency of at least one year.
• Exams. JCNDE says the Integrated National Board Dental Examination (INBDE) is accepted in all U.S. states and territories as all or part of the written licensure requirement. Experienced dentists rarely list it, so use it only in new-graduate searches.
• Specialties and boards. The National Commission on Recognition of Dental Specialties and Certifying Boards recognizes 12 specialties, from dental anesthesiology to prosthodontics, and lists the recognized certifying boards, such as the American Board of Endodontics and the American Board of Orthodontics. The BLS Occupational Outlook Handbook says specialty training is usually a 2- to 4-year residency, and longer for oral and maxillofacial surgery.
• AGD awards. The Academy of General Dentistry's awards page says Fellowship (FAGD) takes 500 hours of approved continuing education and the Fellowship Exam, and Mastership (MAGD) at least 1,100 hours. Both point to a committed general dentist, not to a specialty.

Ten Boolean strings by setting and specialty

Swap in the specialty, procedures and metro from your own intake; these are examples. None of them uses graduation years, names or any other proxy for age or another protected characteristic, and yours should not either.

General and group practice

1. Associate general dentist — LinkedIn general search
("general dentist" OR "associate dentist" OR "family dentist") AND (dds OR dmd OR "doctor of dental surgery" OR "doctor of dental medicine") NOT ("dental hygienist" OR "dental assistant" OR "dental student" OR recruiter)

2. DSO or group practice dentist — LinkedIn Recruiter, Job titles + Keywords filters
("general dentist" OR "associate dentist" OR "lead dentist") AND (dso OR "dental support organization" OR "group practice" OR "multi-location") NOT ("office manager" OR "regional manager" OR recruiter)

3. Dentist who keeps molar endo and extractions — Indeed Smart Sourcing
title: (dentist OR "general dentist") AND skill: ("molar endo" OR "molar root canals" OR "surgical extractions" OR "implant placement") NOT (hygienist OR assistant)

Residency, community health and sedation

4. GPR- or AEGD-trained dentist — LinkedIn general search
(dentist OR dds OR dmd) AND ("general practice residency" OR gpr OR "advanced education in general dentistry" OR aegd) NOT ("ground penetrating radar" OR "dental student")

5. Community health center dentist — LinkedIn general search
("staff dentist" OR "general dentist" OR "dental director") AND (fqhc OR "community health center" OR "federally qualified health center" OR "public health dentistry") NOT ("dental hygienist" OR "dental assistant")

6. Sedation-trained general dentist — Indeed Smart Sourcing
title: (dentist OR "general dentist") AND skill: ("iv sedation" OR "oral conscious sedation" OR "moderate sedation" OR "nitrous oxide") NOT ("surgical assistant" OR "sedation assistant")

Specialists

7. Endodontist — LinkedIn Recruiter, Job titles filter
(endodontist OR "endodontic specialist") AND ("american board of endodontics" OR diplomate OR "board certified" OR "board eligible") NOT ("endodontic assistant" OR "dental student")

8. Orthodontist — LinkedIn general search
(orthodontist OR "orthodontics and dentofacial orthopedics") AND ("american board of orthodontics" OR invisalign OR "clear aligners" OR "orthodontic residency") NOT ("orthodontic assistant" OR "treatment coordinator" OR sales)

9. Pediatric dentist — Indeed Smart Sourcing
title: ("pediatric dentist" OR "pediatric dentistry") AND skill: ("hospital dentistry" OR "general anesthesia" OR "behavior guidance" OR "space maintainers") NOT ("pediatric dental assistant" OR hygienist)

Search-engine X-ray

10. Public profiles by specialty and city — Google X-ray
site:linkedin.com/in "oral and maxillofacial surgeon" "phoenix" -jobs -recruiter -assistant

The X-ray reaches only public, indexed pages; treat what it returns as names to check against the state board.

What LinkedIn, Indeed and Google actually support

As of November 2026, LinkedIn's Boolean help page requires AND, OR and NOT in capitals, supports quotes and parentheses, drops stop words such as "by", "in" and "with", and does not support wildcards, so "dentist", "dentistry" and "dental" have to be written out separately. LinkedIn Recruiter's Boolean page lists Job titles, Companies, Skills and Assessments, Schools and Industries among the filters it treats as Boolean, and warns that too many facets in one query can cause a search result issue. Keep specialty titles in Job titles and procedures in Keywords.

Indeed's healthcare Boolean guide shows a skill: field for the skills section and the fieldofstudy: and school: education fields, and its advanced search post documents title: for a candidate's most recent title and anytitle: for any title they have held. Strings 3, 6 and 9 use title: so that "dentist" has to be the person's own job title, not a word somewhere else on an assistant's resume.

Google's search operators page documents quotes, site:, the minus sign, filetype:, before: and after:, but not OR. That makes an X-ray a one-variant search: run string 10 once for each specialty title rather than joining them with OR.

One official source sits outside the job sites. The NPPES NPI Registry lists providers with their taxonomy and practice location, and CMS's data dissemination page describes it as a query-only database updated daily, with no charge to view it. Its taxonomies include "Dentist, General Practice" and the dental specialties, which makes it a quick way to confirm that a candidate practices where the profile says. It shows nothing about license status or interest in a move.

Narrowing by license state, setting and procedure mix

Start with the license. The BLS says dentists must be licensed in the state in which they work, and the Dentist and Dental Hygienist Compact says that although 13 states have enacted it and it has reached activation status, compact privileges are not yet being issued, as of November 2026. A dentist licensed in a neighboring state may need months to get the client's license, so ask at intake whether the client will wait. If not, keep the location filter on the client's state.

Setting comes next. DSO dentists write about several offices, production targets and lead dentist roles; community health center dentists write about Medicaid, sliding fees and same-day emergencies. One setting block usually changes the list more than any credential term.

Procedure mix decides the rest. If the client keeps molar endo and third molars in house, put those procedures in a required block, as string 3 does, and ask for monthly numbers on the call.

False positives worth excluding with NOT

• Hygienists and assistants. They share the vocabulary and the software. Exclude "dental hygienist", RDH and "dental assistant"; for their own searches, see the dental hygienist strings and the dental assistant strings.
• Office and DSO operations staff. Office managers, treatment coordinators and regional managers write about dentists' production and schedules. Exclude them by title.
• Students, and the DMD collision. Dental students carry every clinical term, so exclude "dental student" for practicing roles. DMD is also the abbreviation for Duchenne muscular dystrophy. Do not answer that with condition words in a NOT block, which can screen people out for a disability-related reason; pair dmd with dentist or dental terms instead, as strings 1 and 4 do.
• Sales, labs and recruiters. Dental supply and implant sales reps, dental lab technicians and dental recruiters mention dentists constantly. Exclude "sales", "dental lab" and "recruiter".
• GPR outside dentistry. GPR is also ground penetrating radar. Spell out "general practice residency" or exclude "ground penetrating radar", as string 4 does.

A worked example: three passes on a community health center search

An invented search, shown as it actually gets narrowed.

The setting words did the narrowing; the procedure words separated the dentists who do the work from the ones who refer it.

What a search cannot verify

A string can find someone whose profile shows the right degree, residency and setting. It cannot confirm that a license, DEA registration or sedation permit is current in the client's state, show what the dentist produces in a day, or tell you how they present a treatment plan to an anxious patient. The dentist screening questions cover license path, permits, procedure mix and production; the license verification guide shows how to record each check; the interview guide for dental roles covers the rest of the practice team; and the 30-60-90 day plan for dentists gives the hire's first quarter a shape.
