Los Algodones, the small border town many patients call "Molar City," sits about three minutes from the Andrade crossing near Yuma, Arizona. Thousands of US and Canadian patients cross each year for cleanings, crowns, root canals, and implants at a fraction of US prices. The most common question we hear is simple: how do I know my dentist is actually licensed?
The good news is that Mexico publishes this information for free, and you can check it yourself in about ten minutes. Here is the step-by-step process.
What a cédula profesional actually is
A cédula profesional is the official license number Mexico issues to a person who has completed a recognized university degree. For a dentist, the base cédula shows the degree Cirujano Dentista (Dental Surgeon), which is the Mexican equivalent of a DDS or DMD. It is issued and tracked by the SEP, Mexico's federal education ministry.
Specialists hold a second cédula for their specialty. An endodontist, periodontist, or oral surgeon should have a separate specialty cédula. This matters: Article 272 Bis of Mexico's General Health Law requires a specialty cédula plus a current certificate from the relevant specialty council before a dentist may legally perform specialty procedures. If someone offers you a surgical extraction, a gum graft, or an implant without a specialty cédula, ask questions.
Step 1: Ask for the full name of the dentist who will treat you
Not the clinic name, and not the owner's name if a different dentist will be working on you. Ask for the full legal name, exactly as it appears on the diploma, of the person who will place the crown, do the root canal, or drill for the implant. A reputable clinic will give it to you without hesitation, by email if you prefer.
Step 2: Open the official SEP portal
Go to cedulaprofesional.sep.gob.mx, the SEP Registro Nacional de Profesionistas. It is free, requires no account, and is the only official source. Avoid third-party "verification" sites that charge a fee or ask for personal data.
Step 3: Search by name, CURP, or cédula number
You can search by full name, CURP, or cédula number. For older records, a name search usually works better than a number search. Enter the dentist's full name as given, including both surnames if provided. Mexican names typically use two surnames (paternal and maternal), so "Ana López García" is more precise than "Ana López."
Step 4: Read the result carefully
The record should show the person's name, the degree earned, the institution, and the cédula number. Confirm three things:
- The name matches the dentist who will treat you.
- The degree reads Cirujano Dentista (or the specialty you were quoted).
- If a specialty procedure was recommended, a separate specialty cédula is listed.
Since 26 September 2025, the portal also lets you download a Constancia de Situación Profesional, a printable official confirmation you can save for your records.
Step 5: Confirm the clinic's COFEPRIS notice
Dental clinics in Mexico must file a sanitary notice, called an aviso de funcionamiento (form COFEPRIS-05-036), with COFEPRIS, Mexico's federal health regulator. That filing requires the treating dentist's cédula and title, so a clinic that has filed properly has already documented its dentists. You can ask the clinic for its COFEPRIS registration details, and you can ask whether the dentist you verified is the one listed.
Why this matters for your wallet, not just your safety
Verification protects you from unlicensed work, but it also protects your savings. Los Algodones prices are low because overhead is low, not because standards are low. A quick comparison from the official 2026 Los Algodones dental price list shows the gap:
| Treatment | Los Algodones (USD) | Typical US price (USD) |
|---|---|---|
| Consultation | Free | $150 |
| Regular cleaning | $30 | $140 |
| Composite filling | $60 | $165 |
| Root canal | $280 (partner promo from $180) | $1,000 |
| Porcelain-fused-to-metal crown | $180 | $1,250 |
| Zirconia crown | $350 (partner promos from $250) | $1,600 |
| Titanium implant + crown and abutment | About $1,300 total | About $3,900 total |
| All-on-4 (per arch) | $8,500 (partner promo $7,500 all-inclusive) | $27,000 |
Prices vary by clinic and by case, so always get a written quote before treatment begins. If your quote involves implants, read our guide to dental implants in Los Algodones; for full-arch cases, see All-on-4. For a broader cost picture, including crowns, root canals, and dentures, the full price list is the best starting point.

Frequently asked questions
Is the SEP cédula lookup really free?
Yes. The Registro Nacional de Profesionistas at cedulaprofesional.sep.gob.mx is free and requires no account. Avoid any site that charges for the same check.
What if the dentist's name does not appear?
Ask the clinic to confirm the exact spelling and both surnames, then search again. If it still does not appear, ask for another dentist or another clinic. A licensed dentist should be easy to find.
Does a cédula guarantee good work?
No. It confirms the dentist is legally licensed and holds the stated degree. Combine it with a written quote, photos of previous cases, and clear answers to your questions.
Do specialists need a second cédula?
Yes. Under Article 272 Bis of Mexico's General Health Law, specialty procedures require a specialty cédula plus a current specialty council certificate.
How far is Los Algodones from Yuma?
About three minutes from the Andrade border crossing near Yuma, Arizona, which makes a same-day verification visit practical.
