Before you send a deposit to any dental clinic abroad, verify the specific surgeon who will perform your procedure through the national credential registry. Every country has one. Every one is publicly searchable. Skipping this step is the #1 preventable mistake in dental tourism.
Country-by-country credential registries
Colombia — ReTHUS
ReTHUS (Registro Único Nacional del Talento Humano en Salud) at rethus.gov.co is the national health talent registry. Every dentist licensed to practice in Colombia is listed. Search by surgeon name to confirm license status, specialty certifications, and any disciplinary history.
How to use it: Enter the surgeon's first and last name in the "Consultar" search box. The system returns license status (active/inactive/suspended), profession, and specialty. Colombia is our #1-ranked destination partly because this registry is so accessible and thorough.
Mexico — CFEO + state dental colleges
Mexico's federal Comisión Federal para la Protección contra Riesgos Sanitarios (COFEPRIS) regulates clinical facilities. Individual surgeon credentialing is handled at the state level through professional dental colleges (colegios dentales). For Los Algodones/Baja California clinics: Colegio Dental de Baja California. For Cancún: Colegio Dental de Quintana Roo.
Turkey — TDA / Türk Dişhekimleri Birliği
Turkey's dental association maintains member registries, but public access from outside Turkey is limited. Ask the clinic directly for the surgeon's TDA member number and their Turkish diploma number, then request that they email you a copy of both.
Costa Rica — Colegio de Cirujanos Dentistas
Costa Rica's dental college publishes a searchable member registry. English-friendly interface. Strong regulatory framework with enforceable disciplinary process.
Hungary / Poland — EU regulatory framework
EU member countries share credentialing framework. Hungarian dentists appear in MFE (Magyar Fogorvosok Egyesülete); Polish dentists in NIL (Naczelna Izba Lekarska dentistry section). Both are publicly searchable.
Thailand — Dental Council of Thailand
Thailand's Dental Council maintains a searchable licensure database. JCI-accredited hospitals (Bumrungrad, Bangkok Hospital) also publish their staff credentialing publicly.
The four warranty red flags that mean walk away
If the clinic only provides warranty terms verbally or only in the local language, you have no enforceable claim. Written warranty in English, signed before the deposit, is non-negotiable.
Some clinics include clauses voiding the warranty if any dental work is done by another provider after the procedure — including emergency care in your home country. This makes the warranty functionally useless for a foreign patient.
Some clinics assign the specific surgeon on the day of the procedure. This makes credential verification impossible in advance. Every reputable clinic will name and credential the specific surgeon before you book.
Legitimate clinics don't need to close you on the initial call. Any "book today for 20% off" pressure is a sales tactic imported from a different industry. Dental work isn't a limited-time offer.
The five questions to ask before you book
- Who is the specific surgeon performing my procedure? (get full name)
- What is their national credential registry number? (verify independently)
- What is your written warranty in English? (get PDF before deposit)
- Which country's courts have jurisdiction if I need to enforce the warranty?
- What is your protocol if I need to return for adjustments? (who pays for what?)
Frequently Asked Questions
Can I verify a US-trained surgeon working abroad?
Yes — check both the US board (ABMS or state dental board for the state they trained in) AND the foreign country's registry. A US-trained surgeon practicing in Colombia should show up on both. If they claim US credentials but don't appear on any US registry, that's a red flag.
What if the clinic won't provide the surgeon's full name for verification?
Walk away. Any clinic that refuses to name the operating surgeon in advance is either hiding a credentialing issue or delegating your case to whoever's available. Both are disqualifying.
How do I know if a surgeon's specialty certification is real?
Every country's dental specialty certification is registered through a national body — Colombia's ACO (Asociación Colombiana de Odontología) tracks specialty certifications separately from base licensure. Ask the clinic for the specialty certification number, then verify it through the appropriate national specialist body.
