RETHUS (Registro Único Nacional del Talento Humano en Salud) is Colombia's official government registry for licensed healthcare providers, including dentists — and checking it directly is one of the simplest, highest-value verification steps available to any patient.
What RETHUS actually confirms
A RETHUS listing confirms a provider holds an active, legitimate license to practice in Colombia — verified by the government, not self-reported by the clinic. This is a baseline credential check, distinct from (and complementary to) specialty certifications a dentist might also hold.
A legitimate clinic will have no hesitation providing the full name their dentist is registered under, so you can check RETHUS independently. Reluctance to share this basic information is itself a meaningful red flag.
What to ask for specifically
- The treating dentist's full legal name, as registered
- Their RETHUS registration number, if available
- Any additional specialty certifications relevant to your specific treatment (implantology, periodontics, cosmetic dentistry)
What RETHUS doesn't tell you
RETHUS confirms licensure, not quality or specific experience with cases like yours. Pair this check with the more specific questions covered in our red flags guide for a fuller picture before booking.
Why this matters more for dental tourism specifically
Because dental treatment is often staged across multiple visits and involves permanent modifications to your teeth, verifying you're working with a genuinely licensed provider — not just a well-marketed clinic — is a foundational, non-negotiable first step.
